Abstract:
In the last few decades, electrostatic precipitators (ESP) have been improvement and many new methods have been implemented to increase in term of Particles collection efficiency in the sub micrometer size range. electrostatic precipitators rely on corona discharge processes to remove airborne dust particles. To understand particle behavior and flow dynamics inside electrostatic precipitators, a precise measurement of the electric field and charge density distribution is required. The electric field and charge density distributions in the negative wire-to-duct electrostatic precipitator were calculated using Poisson and charge conservation equations. typical efficiency of ESP as a function of geometrical and operation factors. In this paper, ESP designed and simulated using COMSOL Multiphysics® 5.5. The effects of the distance between discharge-wires on collection efficiency was studied.

Abstract:
Hybrid electrostatic precipitators consisting of electrostatic precipitation (ESP) and a bag filter are potential devices for ultralow emissions. The ESP captures and charges the particles; subsequently, the charged particles that escape enter the bag filter. The charged particles can cause the electric field of the filter bag to develop, thereby enhancing the filtration efficiency due to the force of the electric field. Experiments based on the coupling-reinforced electrostatic–fabric integrated precipitator system were conducted to investigate the outlet total dust concentration, dust removal efficiency, pressure drop, energy consumption of bag filter, and hybrid electrostatic precipitators with various filter bags. The measured results demonstrate that the removal performance of filter bags with smaller fiber diameters was superior. However, the pressure drop and energy consumption were high due to the increased filtration resistance. Compared to bag filters, hybrid electrostatic precipitators had lower total and grade dust mass concentrations at the outlet, higher total and grade dust removal efficiencies, a minor average pressure drop variation per minute, and lower total energy consumption. Consequently, the quality factor was utilized to comprehensively evaluate the overall performance of dust collectors. The hybrid electrostatic precipitators had a significant greater quality factor; their overall performance was superior to that of bag filters. Overall, a smaller filter bag’s fiber diameter resulted in more effective dust removal capabilities. Hybrid electrostatic precipitators with various filter bags were significantly better than bag filters in terms of dust removal performance, cycle life, and energy consumption.

Abstract:
It has been difficult for the old ESP to meet the new dust emission standards, and the update of the equipment costs a lot of money, therefore, how to reach a higher cost performance becomes the focus of attention. After researches we found that the replacement of the industrial frequency power with the high-frequency inverter of the ESP power can greatly improve the collection efficiency, with a high cost performance and a good prospect of application. The core idea of electrostatic precipitators of high frequency inverter is to transfer three-phase working frequency power into DC power, make use of modernized power electronic technologies and transfer DC power inverter into high frequency AC for control. We can see from this article that electrostatic precipitators of high frequency inverter enjoy the following strengths: (l) Three-phase rectifier transfers three-phase AC power into DC power; the inverter transfers DC voltage into high frequency AC voltage. This method enjoys great flexibility in the control. (2) The output form of high frequency AC voltage square wave in the inverter transfers step-up transformer into high frequency transformer. (3) Compared with the traditional power supply of controllable silicon working frequency phase control electrostatic precipitators, the electrostatic precipitators power supply of high frequency inverter adopts full-controllable power component: IGBT which features swift switch-on/off speed and in case of flashover in the electrostatic precipitators, it is switched off immediately. Research has discovered that high frequency inverter can greatly upgrade the dust collection efficiency, enjoy favorable advancement and very high performance-price ratio and realize broad application prospect.

Abstract:
It is foreseeable that recovery boiler particulate emission limits in the United States and Canada will continue to get more stringent with time. Because of this, continued improvement of emission control equipment, as well as a better understanding of how operating parameters affect performance, are necessary. Although electrostatic precipitators (ESPs) are often viewed as a mature technology, many improvements in ESP technology continue to be developed. In recent years, academic efforts have improved the understanding of recovery boiler operating conditions on ESP performance. Additionally, advancements in materials, power supplies, and design continue to improve the efficiency and reliability of ESPs. This paper discusses how recovery boiler and electrostatic precipitator (ESP) operating factors affect ESP performance based on process simulations and practical experience, and how these learnings can be implemented to improve future operation of existing ESPs.

Abstract:
Recently, submicron particles have been discussed as a means to increase the bioavailability of poorly water-soluble drugs. Separation of these small particles is done with both fibre and membrane filters, as well as electrostatic precipitators. A major disadvantage of an electrostatic precipitator (ESP) is the agglomerate formation on the precipitation electrode. These agglomerates frequently show low bioavailability, due to the decreased specific surface area and poor wettability. In this work, a new melt electrostatic precipitator was developed and tested to convert submicron particles into a solid dispersion in order to increase the bioavailability of active pharmaceutical ingredients. The submicron particles were generated by spray drying and transferred to the ESP, where the collection electrode is covered with a melt, which served as matrix after solidification. The newly developed melt electrostatic precipitator was able to collect isolated naproxen particles in a molten carrier. A solid naproxen xylitol dispersion was prepared, which showed a reduction of the dissolution time by 82%, and a release of 80% of the total drug, compared to the physical mixture.

Abstract:
In thermal power stations, flue gases are let to the atmospheric air through the chimney. This exhaust gas contains some toxic elements like Suspended Particle Matter (SPM), SOX, NOX, Mercury etc. It causes air pollution in the atmosphere and affects the human beings and aquatic lives. The allowable limit of this flue gas dust emission to the atmosphere is about 50 mg/m3. In order to separate this dust particle from the flue gas, Electrostatic Precipitators (ESP) are used to collect those unwanted suspended particles before passing them to chimney. ESP requires high efficiency to extract those dust and hence, High-Frequency High Voltage (HFHV) power supply is applied to increase the efficiency of the collecting electrode of the electrostatic precipitator. The HFHV power supply provides a significant reduction in the size and weight of the complete ESP installation.

Abstract:
Gaseous exhausts from various industries pollute the environment with fly-ash generally filtered by electrostatic precipitators (ESPs) before being released to the atmosphere. This paper presents the development of a controller for ESP power supply. The controller maintains the voltage applied to ESP at its maximum average value by duty cycle control that results in an improvement in dust collection-efficiency. The limiting factor for the output voltage is the breakdown of gas (spark/arc) in the electrode gap of ESP. During a spark/arc condition, the duty cycle limit imposed by the controller causes a reduction in output voltage that leads to the prevention of spark/arc. The present design has a response faster than line frequency power supply controllers. The control circuit is simpler, easy to implement and uses a standard PWM controller IC. The design of power stage uses a flyback current-fed push-pull DC-DC converter with multiple secondary circuits, which has the advantages of instantaneous current limit and less voltage stress on rectifier-diodes. Simulation is performed to obtain a 1 kV, 100 W output from a 24VDC source. The results are compared with experimental values to validate the controller’s ability to achieve good load regulation during normal operation and a reduction in output voltage during spark/arc condition.

Abstract:
The performance of Electrostatic Precipitator (ESP) is significantly affected by complex flow distribution. Recent years, many numerical models have been developed to model the particle motion in the electrostatic precipitators. The computational fluid dynamics (CFD) code FLUENT is used in description of the turbulent gas flow and the particle motion under electrostatic forces. The gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modeled by the k-ε turbulence model. The effect of electric field is described by a series equations, such as the electric field and charge transport equations, the charged particle equation, the charge conservation equation, the mass and momentum equations of gas, the mass and momentum equations of particle and so on. The particle phase is simulated by using Discrete Phase Model (DPM). The simulations showed that the particle trajectory inside the ESP is influenced by both the aerodynamic and electrostatic forces. The simulated results have been validated by the established data.

Abstract:
The electrostatic precipitators (ESP) have been drawing more and more attention due to their high efficiency and low costs. Numerical simulation is a powerful, economical and flexible tool to design ESP for industry applications. This review summarizes the available numerical models to simulate different physical processes in ESP, including ionized electric field, air flow, particle charging and motion. It has been confirmed that the available models could provide acceptable results and the computing requirements are affordable in industry applications. The coupling between different physical processes can also be considered in simulation. However, there are still some problems not solved, such as selection of a suitable turbulence model in EHD simulation and the coupling criteria. The future study should focus on these issues. This review also includes new types of ESP developed in recent years, such as dielectric barrier discharge (DBD) ESP and corona assisted fibrous filter. These new types of ESP have had high efficiency and low energy consumption. Even though nearly all new ESP types can be modeled using the available numerical models, the most challenging issue is the DBD simulation.

Abstract:
Electrostatic precipitators (ESP) have been widely used to remove particles from exhausted gases in many industrial processes. The performance of ESPs is affected by operating parameters such as inlet velocity, applied voltage and other factors. A numerical method of multi-field coupling is used to study the influence of different factors on the distributions of electric field and flow field in an ESP. The results show that the particle collection efficiency of 0.1–10 µm particles has a U-shaped distribution relationship with particle size. With the increase of applied voltage and electrode length, and the decrease of inlet velocity and anode-cathode distance, the particle collection efficiency increases. The established numerical model and corresponding conclusion can provide some guidance for the optimal design of ESPs.

Abstract:
A dust layer, especially based on high-resistivity dust, at the collecting electrodes may cause a back corona discharge in electrostatic precipitators (ESP). It can significantly reduce the ESP efficiency and as a result cause ecological damages. To study the dust layer influence inside ESPs, it is necessary to derive an adequate model of the ESP precipitation process with a dust layer at the collecting electrode. The research of the present thesis is focused on stationary studies of the precipitation process with a dust layer at the collecting electrode in ESPs. Three mathematical models are proposed as a description of the precipitation process with a dust layer at the collecting electrode. The models are based on Maxwell’s equations and the finite element method (FEM). COMSOL Multiphysics software is used for their implementation. In all models the dust layer has constant conductivity and the air region has constant ion mobility. In the first model there are no coupling conditions, which is required in mathematics, are given between the two regions. The solution found by COMSOL Multiphysics does not provide physically acceptable coupling conditions. In the second model, a continuous transition zone is introduced between the two regions so that no coupling conditions are required. With the large derivatives in the transition zone, the nonlinear solver in COMSOL Multiphysics does not converge. Finally, in the third model, the dust layer and the grounded collecting electrode are replaced with a boundary condition for the air region. The properties of the third model are investigated, and these models can be used to study the influence of the dust layer. The results of these investigations are reported and discussed.

Abstract:
Increasingly more stringent particulate standards in India are being met by large and expensive electrostatic precipitators for new coal-fired power stations. The older and smaller units require upgrades. The Proactive Approach combining experience and knowledge with the application of a modern ESP model has been developed to help identify low-cost upgrade options. The approach was applied to a poorly operating medium sized Indian ESP not meeting the newer regulations. After defining the discharge electrode and particle size properties the precipitator was virtually restored to its proper design performance within the computer. Then a number of relatively low-cost options were identified to increase the migration velocity and decrease the gas flow. These approaches indicated that the precipitator could achieve lower emission levels that could meet the newer emission requirements. The Proactive Approach is easily and economically applicable to other precipitators in India and elsewhere.

Abstract:
Electrostatic precipitator (ESP) modeling development has reached the point in which internal algorithms completely simulate the operation and particulate collection physics of full-scale units. The modern ESPVI 4.0 series of models by using advanced techniques are able to evaluate changes in a precipitator’s configuration and operation to optimize its performance. The author’s applied these techniques to ESPs’ at the Kashira Power Plant near Moscow, having relatively small specific collector area’s (SCA), whose performance will have to be enhanced to meet emerging standards. Advanced modeling techniques include determining electrode and particle properties, operation below back corona onset, and effects of improved electrodes and electrical conditions. The precipitators with collection efficiencies of 88.4 (without natural gas co-firing) up to 93% (with partial co-firing) are shown to be capable of efficiencies of up to 99% by application of modest changes in configuration and operation. The advanced modeling techniques described in this paper are not only important for Kashira, they are also applicable to other power stations requiring performance optimization.

Abstract:
Polk County owns and operates two starved air mass burn municipal solid waste combustors serving a five County region in rural Northwest Minnesota. The plant was constructed in 1987 and began burning MSW in 1988. Each unit has a combustion capacity of 40 tons per day producing energy in the form of saturated steam for two customers in the adjacent industrial park. The plant utilizes a two field electrostatic precipitator (ESP) as the air pollution control device for each unit. In 1996, a materials recovery system was constructed in front of the waste combustors to remove problem/objectionable items. This facility is providing many benefits including reduced stack emissions, lower O & M costs for the WTE units, and revenues from the sales of extracted recyclables. Both facilities have operated successfully since startup. EPA emission guidelines for existing small waste combustors were originally promulgated in December 1995. These guidelines set more stringent limits for pollutants currently regulated and added limits for several other pollutants previously unregulated. However, litigation set aside these 1995 emission guidelines for small waste combustors until they were re-established by EPA in December 2000. Pending release of the year 2000 emission guidelines, the Minnesota Pollution Control Agency stayed the State rule and issued a Rule variance in 1998 that included new limits for mercury, and dioxins/furans. In order to attain compliance with the new State limit for dioxin/furans, Polk began injecting powdered activated carbon into the flue gas of each unit upstream of the ESP. The emission guidelines are technology based, and EPA concluded that small existing waste combustors could maintain operation of the electrostatic precipitators. Compliance with the guidelines could be attained with an ESP upgrade or added collection field in conjunction with the addition of other pollution control equipment. Was the EPA right? Can this technology comply with the guidelines? This paper will discuss the development of an APC retrofit project for a small waste combustor whose goal was to attain full compliance with the revised air emission guidelines while maintaining operation of the existing electrostatic precipitators.

Full text
Abstract:
Proposed modifications to the laws governing the emissions from biomass fired boilers require more stringent control on emissions. During biomass combustion there are several pollutants produced which require advanced pollution control measures to maintain environmental compliance. These pollutants include Particulate Matter, Hydrogen Chloride, Sulfur Dioxide, Sulfuric Acid Mist, and Oxides of Nitrogen. To ensure operational compliance of the boiler’s stack emissions both now and in the future, proper pollution control technology is paramount. This presentation will address an emerging air pollution control technology that embodies all of these removal steps in a single device specifically designed to meet the needs of biomass fired boilers. Historically, the control strategy for stack emissions from such boilers has included the use of various standalone systems. For example, Dry Electrostatic Precipitators have been used for PM reduction, Selective Non-Catalytic Reduction systems for NOx control, Flue Gas Desulphurization for SO2 removal, and single pass Wet Electrostatic Precipitators for H2SO4 abatement. The consolidation of these multiple, standalone systems into a smaller, less costly alternative tailored specifically for biomass fired boilers can address the new requirements. EISENMANN’s recently patented multi-pollutant control system includes the use of a pre-scrubbing chamber for large PM, SO2, and water soluble NO2 removal. Following the quench and pre-scrubbing region, a specially tuned downflow wet ESP field is responsible for finer PM and Sulfuric Acid aerosol removal, as well as an important Ozone producing stage that oxidizes non-water soluble NO. As the gas continues to travel through the system, a secondary scrubbing chamber is used to further reduce NOx by scrubbing the newly formed NO2 that has been formed from the oxidation of NO through the use of Ozone produced by the electrostatic precipitator. The final polishing stage of the system includes an upflow wet electrostatic precipitator field for the removal of newly oxidized material such as mercury. Research and testing on the aforementioned system took place through the development of a pilot sized unit. Expected performance was validated proving high removal efficiencies for pollutants specifically addressed earlier. Implementation of the technology within the biomass fired area is underway and is currently viewed as an acceptable solution to the environmental regulations associated with a biomass fired boiler because of the smaller footprint, lower operating costs, and overall condensed solution when compared to previously used technologies.

Since then there have been a number of important developments of technology, notably combination with an ESP, use of integrated lime hydration and use of ash from CFB as the reagent; supported by an ongoing test program. The technology also looks promising for the retrofit area. The combined full-scale plant for the removal of flyash and SO2 can often be fitted into the space occupied by the existing electrostatic precipitators. There are seventeen commercial installations of FDA in various stages of operation, construction, and design.

Full text
Abstract:
The newly promulgated EPA MACT rules for solid waste incinerators require HCl to be mitigated to extremely low concentrations. Most existing air pollution control systems will probably not be able to satisfy these very low limits. To meet the new challenges, dry injection of sodium bicarbonate or trona is a low-cost solution that can be applied in the following situations: (1) Replace existing acid gas mitigation systems; (2) Supplement existing systems; (3) Install where no acid gas mitigation systems exist yet. In a dry sorbent injection system, sodium bicarbonate or trona is injected directly into hot flue gas. After injection, the sorbent is calcined into porous activated sodium carbonate. Its high surface area enables fast gas-solid reactions between acid gases (mainly HCl and SO2) and Na2CO3 to form NaCl and Na2SO4 which are collected by either electrostatic precipitators (ESP) or fabric filters. The dry injection systems with sodium bicarbonate have shown over 99% removal of HCl and 95% removal of SO2 at over 150 Waste-To-Energy plants in Europe. This paper will describe the concept of dry sorbent injection system with sodium bicarbonate or trona, provide performance data from several plants, and describe system design guidelines.

Abstract The SEMASS Resource Recovery Facility (SEMASS) is a processed refuse fuel (PRF) waste-to-energy plant serving much of Southeastern Massachusetts. Units 1 and 2 at the plant were designed with spray dryer absorbers (SDAs) and electrostatic precipitators (ESPs). A review of historical data from the plant indicated that in order to comply with the Environmental Protection Agency’s Municipal Waste Combustor (MWC) Rule (40 CFR Part 60, Subpart Cb), which is known as the Maximum Achievable Control Technology (MACT), improved emission performance would be required from the flue gas cleaning system on Units 1 and 2. A pilot test program was conducted which led to the installation of COHPAC, or COmpact Hybrid PArticulate Collector units (i.e. flue gas polishing devices) downstream of the ESPs on these two combustion trains. The COHPAC units were successfully started up in June, 2000. In addition to these modifications, it was determined that further control of mercury emissions would be required. A system to inject powdered activated carbon into the flue gas was added to the plant. This paper describes that carbon injection system. A comparison between test data obtained at SEMASS is made with predictions based upon the EPA testing at the Ogden Martin Systems of Stanislaus, Inc. Municipal Waste Combustor Facility near Crows Landing, California and the EPA testing at the Camden County Municipal Waste Combustor in Camden, New Jersey. These are waste-to-energy plants, the former utilizing an SDA and a baghouse while the latter contains an SDA followed by an ESP. In addition, the effect of carbon injection location upon mercury reduction was investigated. The results of that study are also included.

Abstract:
NYU has an ongoing research program which is being funded by DOE to test three types of high-pressure, high-temperature filters. The main objectives of the testing program are: (1) to establish the performance capability of the filters under high-pressure and high-temperature conditions; and (2) to evaluate the dust collection efficiency. Shakedown tests for a duration of about 50 hours was completed during October 1986. Testing of the electrostatic precipitator (ESP) is in progress. The first test with ESP was performed during the middle of November 1986. The operating experience with respect to the test facility, and in particular with the particulate sampling systems, is reported in this paper. Additionally, some test results are also discussed.

Abstract:
With the development of modern industry, the separation of suspended droplets from the gaseous flow has become increasingly important. In many industrial applications it is required to control the fine liquid droplets concentration in moving gaseous media. Refrigeration and Heating Ventilation Air Conditioning (HVAC) system is one major application. Electrostatic Precipitator (ESP) can be adopted for separation of fine droplets in gases, since corona discharge could charge these droplets, then use of electrostatic force to implement separation and collection. However, separation of droplets in gaseous flow is a complex process which is combination of electrostatic and flow field. The current study investigates effects of key parameters like applied voltage, flow temperature, flow velocity and particle’s size on particles separation efficiency using a wire-cylinder assembly. Monodisperse particles are used in this study where above mentioned parameters have shown significant effect on the separation efficiency.
