Current trends in the development of power engineering are turning attention towards modernization of the machinery and equipment. Modernization of the LP (low-pressure) part of a turbine is one of the most promising solutions. A natural question which arises concerns the effectiveness of such modernization, i.e. a comparison of the characteristics (efficiency) of this turbine part before and after modernization. Such a comparison may be based on measurements of the efficiency of the LP part and the last stage before and after the modernization, provided that the efficiency gain achieved exceeds the measuring error. This paper deals with the estimation of the accuracy of such a measurement, the principle and methodology of which have been developed at the Institute of Fluid-Flow Machinery (IFFM) for a real turbine.

The production of energy in wind power plants is regarded as ecologically clean because there being no direct emissions of harmful substances during the conversion of wind energy into electricity. The production and operation of wind power plant components make use of the significant potential of materials such as steel, plastics, concrete, oils, and greases. Energy is also used, which is a source of potential negative environmental impacts. Servicing a wind farm power plant during its operational years, which lasts most often 25 years, followed by its disassembly, involves energy expenditures as well as the recovery of post-construction material potential. There is little research in the world literature on models and methodologies addressing analyses of the environmental and energy aspects of wind turbine modernization, whether in reference to turbines within their respective lifecycles or to those which have already completed them. The paper presents an attempt to solve the problems of wind turbine modernization in terms of balancing energy and material potentials. The aim of sustainable modernization is to overhaul: assemblies, components, and elements of wind power plants to extend selected phases as well as the lifecycle thereof while maintaining a high quality of power and energy; high energy, environmental, and economic efficiency; and low harmfulness to operators, operational functions, the environment, and other technical systems. The aim of the study is to develop a methodology to assess the efficiency of energy and environmental costs incurred during the 25-year lifecycle of a 2 MW wind power plant and of the very same power plant undergoing sustainable modernization to extend its lifecycle to 50 years. The analytical and research procedure conducted is a new model and methodological approach, one which is a valuable source of data for the sustainable lifecycle management of wind power plants in an economy focused on process efficiency and the sustainability of energy and material resources.

The application of a gas turbine generally allows to increase the number of possible configurations of cogenerated heat and electrical power systems, which became a significant substitute for classic, coal-fired power plants. They are characterized by better thermodynamical, economical, ecological, and operating indexes. Gas turbine units are also the best option for the modernization of existing power plants. This paper discusses the effectiveness of various technological configurations with gas turbines, which are to be applied during modernization projects of already existing conventional combined heat and power plants. In the analysis enthalpy and entropy methods were applied. Algorithms of the entropy method allow to determine the entropy generation in each section of a combined heat and power (CHP) plant. Several criteria were taken into consideration while analyzing the effectiveness of technological cycle configurations with gas turbines. These include the energy effectiveness, the efficiency of the HRSG and the steam cycle, the efficiency of the whole thermal electric power station, the exergetic efficiency of the HRSG and the steam cycle, and the fuel efficiency index. It was assumed that gas turbines operate under their nominal conditions. The composite curves were also taken into consideration while choosing the type of the turbine. The modernization project tends not to eliminate those existing power plant sections (machines and equipment), which are able to operate further. The project suggests that those units should remain in the system, which satisfy the applied durability criterion. The last phase of the optimization project focuses on the sensibility verification of several steam-gas CHP plant parameters and their influence on the whole system.

At high ambient temperatures, the performance of gas turbine power plants drops significantly. Technical solutions of compensation for losses associated with the constant injection of water into the air intake of a gas turbine. This approach is not acceptable in regions with limited fresh water reserves. Radical solutions are required to reduce the cost of generated energy. Integrated Combined Solar Cycle (ISCCS) technology has proven itself on many projects. The addition of a combined cycle gas cycle with solar energy can significantly increase the overall efficiency of the power plant. Despite the increase in costs during the construction of its solar part, the total cost of operating solar collectors is several times less than a turbine installation. Given the global trend to fight carbon emissions, switching to a hybrid scheme is economically attractive. Trading in carbon credits for CO2 emissions will significantly reduce the payback period for the construction of gas turbine modernization under the ISCCS scheme. This paper presents an option to modernize a gas turbine power plant in the city of Basra (Iraq), using the advantages of solar radiation and recycling of combustion products from gas turbines. It is proposed to equip the existing 200 MW gas turbine plant with two steam turbine units with a capacity of 75 and 65 MW, working in conjunction with solar collectors producing low pressure water vapor. Due to modernization, the efficiency of the power plant should increase from 38% to 55%. The revision of the schematic and technical solutions of Iraq power plants will allow producing sufficient energy for the region.

Modernization of sealing units with a change of design is carried out in order to improve the technical and economic parameters of steam turbines. It is known from experience of operation of the turbine equipment that, ring cracks in rotors arise in sealing areas. This is due to both seals design features and the accumulation of thermocyclic fatigue. The research is devoted to the study of resource parameters of the high-pressure rotor of the T-250/300-240 turbine equipped with seals of labyrinth, honeycomb and direct-flow type. Numerical experiments were performed on the basis of three-dimensional geometric models of interflow end seals of the high pressure rotor. The finite element method is used to discretize the computational area. The thermal state of the turbine is calculated for the starting mode from the cold state of the metal by solving the boundary value problem of thermal conductivity in a non-stationary setting. The calculation of the stress-strain state of the turbine takes into account the obtained data on temperature stresses and forces from the non-uniformity of temperature fields, as well as centrifugal forces and steam pressure. Differences in the stress-strain state of the rotor for different seal designs are established. It is indicated that after grooving of labyrinth interflow seals to the honeycomb structure, the stress level in the rotor decreased by 8 %, and when grooving to the direct-flow structure — by 21 %. The accumulated damage in the main metal of the turbine was determined using experimental curves of long-term strength of steel 25Cr1Mo1V. The calculation of resource indicators showed that in the transition from the labyrinth to the honeycomb design of the seals, the individual resource of the high-pressure rotor increases by 6.1 %, and in the transition to direct-flow — by 14.4 %.

The current state of the energy sector is analyzed, the physical and moral obsolescence of the main equipment is revealed, the losses of electricity in the networks are increased. Coal combustion at power plants is accompanied by increased man-made load on the environment. To increase the energy, economic and environmental efficiency of energy supply of industrial enterprises, the use of decentralized cogeneration based on gas industrial boilers or the use of biomass boilers is proposed. Options for energy modernization on the example of an industrial dairy boiler house are considered. 8 variants of increase of reliability, energy efficiency, economy and environmental friendliness are offered, namely installation of boilers on biomass, gas turbine and gas-piston heat engines, creation of thermal power plant with steam turbine installation on saturated and superheated steam. The analysis of advantages and disadvantages of variants, and also rationality of their introduction on boiler houses of the industrial enterprise is executed. Calculations of economic indicators of different options for energy modernization of the boiler house allowed to identify effective methods to increase the efficiency of energy equipment. The analysis also takes into account the possibility of diversification of energy supply and reduction of dependence on electricity suppliers.

The Waidhaus compressor station in Germany is a key compressor station for the supply of Natural Gas from Russia into the German and the European market. The required flexibility, together with the goal of a small environmental footprint, has led to some unique, but widely applicable solutions. Since this head compressor station of the MEGAL pipeline system is of highest importance for the European gas supply, requirements for high availability and reliability of the equipment are significant. The paper consists of two parts: In the first part it describes the challenges of installing new equipment in an existing compressor station, details the characteristics of the installed equipment, and, in particular, discusses the steps that have been taken to assure the required high availability, high reliability, and high flexibility. In the second part, the acceptance test is described, taking into account site specific limitations, and how a highly accurate site test can be executed. The tested unit was accepted based on the acceptance test described. The methodology is useful for the conduct and execution of site performance tests. The paper thus provides insight into the decision making, installation, and acceptance process for the specific situation of a strategically important brownfield compressor station.

Siemens Power Generation has recently completed a number of first time applications of Steam Turbine modernizations on its OEM fleet. This paper will discuss the R&D approach taken in developing these first-time solutions to help achieve and focus on case studies of completed projects that demonstrate the end result of this approach. Projects planned to be discussed are modernizations implemented in the last year (2007–2008) of a VHP/HP turbine steam path replacement, a full element HP/IP replacement, and applications on large fossil LP turbine replacements. Current industry challenges that will be discussed include resource constraints in engineering, material supply chain, and factory delivery slots that are escalating prices and increasing delivery times of replacement turbine equipment. Some of the actions the author’s company is taking to mitigate these issues, such as gaining earlier commitments, use of material indices, and others will be discussed to help utilities looking at undertaking a turbine modernization gain a better insight into vendor challenges.

Low pressure compressor operation has some features. Firstly, the LPC stages work with cold air. For this reason there is transonic or subsonic flow in LPC. Secondly, the flow in LPC has complex spatial structure. Blade geometry of LPC is described by a large number of parameters. For this reason, it is difficult to pick up optimal combination of parameters manually. The solution of this problem is the usage of optimization methods to find the optimal combination of parameters. This approach was tested in this work. The main goal of this work was the LPC modernization for new parameters of gas turbine engine. Set of unimprovable solutions (Pareto set) was obtained as a result of solving optimization task. Pareto set was a compromise between the efficiency increase and the mass flow decrease. Each point from Pareto set had a correspondence with LPC unique geometry represented as an array of optimization parameters. One point of the Pareto set met all the required parameters of modernized LPC. The LPC geometry that guaranteed the efficiency increase by 1,3%, the total pressure ratio increase by 4% and mass flow rate decrease by 11% in comparison with the original LPC was obtained as a result of the investigation.

Coal-fired power plants that survive into the future and avoid being displaced by combined cycle plants and wind turbines will require air quality control (AQC) equipment to conform to EPA requirements per the Cross State Air Pollution Rule (CSAPR). This AQCS can consume 5–10% parasitic load of a coal-fired unit’s output. This paper will provide discussion on recent industry trends of utilities pushing to implement modernization projects for parasitic load recapture and also other benefits such as life extension, improved maintenance, better efficiency, availability, and reliability. The three main strategies discussed will be: • Boiler and Turbine Optimization options • Steam Turbine Modernization with the latest technology steam path • Steam Valve Modernization Coal-fired plants have been careful to implement these types of projects without additional heat input in- order to avoid any new source review issues. Recent industry examples and development efforts will be discussed in this paper to provide an overview of these options current available or that will be available in the near future for coal-fired power plants.
