Повний текст джерелаThe generation of electricity by the combustion of pulverised coal produces large quantities of coal ash (PF A). The disposal of this ash lias become a matter of concern due to the unsightly and hazardous nature of the PF A, and it has been the subject of intense investigations into its suitability as a raw material. Many uses have been proposed for the PF A. When used as landfill or mining backfill, the attraction is the low cost of the material. Other uses, as in the concrete industry, use PF A because of the improvements in quality of the resultant product. PF A has been suggested as a raw material for the production of wear resistant materials. The PF A is composed in the main of SiO₂ and AI₂O₃, and is a suitable material for the production of alumino-silicate ceramic materials, which are known to be tough and wear resistant. To establish the suitability of PF A from the Lethabo Power Station as a raw material, a project to prepare glass ceramic materials from the PF A was started. The conversion of the PF A to a glass ceramic material is a complex process involving many stages, and the processing at each stage will affects the final properties of the material. It is not possible in a short project such as this to examine all the factors which exert some control on the process, and so a small subset of these parameters was selected for study, namely the effect of added oxides on the crystallisation behaviour. Glass items which crystallise on holding at high temperatures commonly do so by growth of crystals from the surface of the item. This results in a material that is mechanically weak, due to the highly oriented microstructure that results. Nucleating agents can be used to obviate this. By providing sites for crystal growth in the bulk of the sample, they induce the crystallisation of fine grained ceramics with good mechanical properties. This study examines the effect of TiO₂, P₂O₅, and a mixture of iron and chrome oxides on the crystallisation of the glass prepared using PF A. The effect of these oxides was evaluated by examination of the microstructure of the crystalline specimens, and the kinetics of crystallisation were analysed by fitting data obtained by isothermal crystallisation of the specimens to the Avrami equation. Finally, the mechanical properties of the materials were tested by solid particle erosion, and the materials ranked against a selection of other materials used for their wear resistance.

Повний текст джерелаThe chemical and mineral compositions are presented for 63 pulverized fuel ash (PFA) and 16 input coal samples collected from Lethabo, Duvha and Matla power stations over the period 1987-1988. Bulk chemical composition was determined by X-ray fluorescence spectrometry. The mineral concentrations were determined by semi-quantitative X-ray diffraction based on integrated counts over peak areas, with silicon used as an internal standard. The particle size distributions were determined for two sample sets from each power station with a Malvern Instruments Particle Sizer. The major phases present in the ash are glass ( 45-75% ), mullite (16-39%) and quartz (1.5-16% ). The quartz concentration decreases in PF A from fields 1 to 4 in all the stations, and is positively correlated with the SiO₂ concentration. The concentrations of glass, mullite and quartz in PFA generally vary within well defined limits which remain constant with time. An exception is the glass concentration in Duvha PFA. Spinel concentration generally decreases in concentration in PFA from fields 1 to 4, and is positively correlated with the Fe₂O₃ concentration. Of the trace elements determined, Zr, Rb and Mn generally have no or very low enrichment in concentration in PFA from fields 1 to 4. The highest enrichment factors ( > 5) were found for As, Ge and Se in Duvha PF A. The composition of the glass and ferrite spinel phases were determined by electron microprobe analysis. The glass consists of SiO₂ (21-100%) and Al₂ O₃ (0.1-49%), with significant proportions of CaO, TiO₂, Fe₂O₃ and MgO. Al₂O₃ , MgO and TiO₂ substitute for FeO in the spinel structure, with MgO substitution dominant in Duvha spinels. Chemical mass balance calculations suggest that of the elements determined for Lethabo PFA, the only one released in a significant proportion to the atmosphere is S(92% ).

Повний текст джерелаThis licentiate thesis describes development of modellingtools, experimental physical modelling and numerical modellingto simulate real combustion processes for advanced industrialutility boiler before and after retrofit.
The work presents extended study about formation,destruction and control of pollutants, especially NOx, whichoccur during combustion process.
The main aim of this work is to improve mixing process incombustion chamber. To do this, the optimization of placementand direction of additional air and fuel nozzles, the physicalmodelling technique is used. By using that method, it ispossible to obtain qualitative information about processes,which occur in the real boiler. The numerical simulationsverify the results from physical modelling, because duringmathematical modelling quantitative informations about flow andmixing patterns, temperature field, species concentration areobtained.
Two 3D cases, before and after retrofit, of pulverized fuelfired boiler at 125 MW output thermal power are simulated. Theunstructured mesh technique is also used to discretize theboiler. The number of grid was 427 656 before retrofit and 513362 after retrofit. The comparisons of results of numericalsimulation before and after retrofit are presented. The resultsfrom physical modelling and numerical simulation are alsoshown.
Results present that nozzles of additional air and fuel givea considerably better mixing process, uniform temperature fieldand CO2 mass fraction. The whole combustion chamber worksalmost as a "well stirred reactor", while upper part of boilerworks as a "plug flow reactor".
Differences between from measured of temperatures andpredicted temperatures are not too big, the maximum differenceis about 100 K. It seems, that calculated temperatures showgood agreement with measurement data.
The results illuminate the potential of physical andnumerical modelling methods as promising tools to deal with thecomplicated combustion processes, even for practicalapplication in the industry.
Keywords:air staging, fuel staging, boiler, furnace,computational fluid dynamics, numerical simulation, pollutants,physical modeling, pulverized fuel combustion.
