Available in PDF, EPUB and Kindle. Book excerpt: Advanced coal and biomass-based gas turbine power generation technologies (IGCC, PFBC, PCFBC, and Hipps) are currently under development and demonstration. Efforts at the Siemens Westinghouse Power Corporation (SWPC) have been focused on the development and demonstration of hot gas filter systems as an enabling technology for power generation. As part of the demonstration effort, SWPC has been actively involved in the development of advanced filter materials and component configuration, has participated in numerous surveillance programs characterizing the material properties and microstructure of field-tested filter elements, and has undertaken extended, accelerated filter life testing programs. This report reviews SWPC's material and component assessment efforts, identifying the performance, stability, and life of porous commercial metal, advanced alloy, and intermetallic filters under simulated, pressurized fluidized-bed combustion (PFBC) conditions.

Book excerpt: Hot gas filtration in pressurized fluidized bed combustion (PFBC) systems has been proven below 750 C (1400 F). Advanced PFBC designs, focused on operational and efficiency improvements, will require filtration at higher temperatures. E.g., in first-generation advanced PFBCs, the filters will have to perform at 870 C (1600 F), while second-generation units, with both carbonizers for fuel-gas production and fluidized-bed combustors, will eventually require filters to operate up to 930 and 870 C (1700 and 1600 F). Results from the final test campaign at the Tidd PFBC Demonstration Project showed that at these higher temperatures, ceramic filter reliability may be problematical, so it will be of interest to re-examine the possibility of using advanced metal hot-gas filters for these advanced PFBC applications in view of the exceptional corrosion resistance of Fe aluminides in high-temperature sulfur-bearing atmospheres. For the second-generation PFBCs, performance criteria for the carbonizer filters are essentially the same as those for integrated gasification combined cycle systems (reducing environments). For the combustor, issues are similar to those of advanced first-generation units (oxidizing) except that the fuel (byproduct char from carbonizer) should be somewhat clearer and filter performance requirements less demanding than for PFBC systems such as the Tidd plant. For the carbonizer system, the nearer term (market entry) goals are to develop filter materials that will perform at 650-760 C (1200-1400 F), with an increase to 800-930 C (1500-1700 F) for improved cycle efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: Fossil-fuel power plants account for the majority of worldwide power generation. Increasing global energy demands, coupled with issues of ageing and inefficient power plants, have led to new power plant construction programmes. As cheaper fossil fuel resources are exhausted and emissions criteria are tightened, utilities are turning to power plants designed with performance in mind to satisfy requirements for improved capacity, efficiency, and environmental characteristics. Advanced power plant materials, design and technology provides a comprehensive reference on the state of the art of gas-fired and coal-fired power plants, their major components and performance improvement options. Part one critically reviews advanced power plant designs which target both higher efficiency and flexible operation, including reviews of combined cycle technology and materials performance issues. Part two reviews major plant components for improved operation, including advanced membrane technology for both hydrogen (H2) and carbon dioxide (CO2) separation, as well as flue gas handling technologies for improved emissions control of sulphur oxides (SOx), nitrogen oxides (NOx), mercury, ash and particulates. The section concludes with coverage of high-temperature sensors, and monitoring and control technology that are essential to power plant operation and performance optimisation. Part three begins with coverage of low-rank coal upgrading and biomass resource utilisation for improved power plant fuel flexibility. Routes to improve the environmental impact are also reviewed, with chapters detailing the integration of underground coal gasification and the application of carbon dioxide (CO2) capture and storage. Finally, improved generation performance is reviewed with coverage of syngas and hydrogen (H2) production from fossil-fuel feedstocks. With its distinguished international team of contributors, Advanced power plant materials, design and technology is a standard reference for all power plant engineers and operators, as well as to academics and researchers in this field. Provides a comprehensive reference on the state-of-the-art gas-fired and coal-fired power plants, their major components and performance improvement options Examines major plant components for improved operation as well as flue gas handling technologies for improved emissions control Routes to improve environmental impact are discussed with chapters detailing the integration of underground coal gasification

This book was released on 2010-03-18 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power Generation from Solid Fuels introduces the different technologies to produce heat and power from solid fossil (hard coal, brown coal) and renewable (biomass, waste) fuels, such as combustion and gasification, steam power plants and combined cycles etc. The book discusses technologies with regard to their efficiency, emissions, operational behavior, residues and costs. Besides proven state of the art processes, the focus is on the potential of new technologies currently under development or demonstration. The main motivation of the book is to explain the technical possibilities for reducing CO2 emissions from solid fuels. The strategies which are treated are: more efficient power and heat generation technologies, processes for the utilisation of renewable solid fuels, such as biomass and waste, and technologies for carbon capture and storage. Power Generation from Solid Fuels provides, both to academia and industry, a concise treatment of industrial combustion of all types of solid, hopefully inspiring the next generation of engineers and scientists.

This book was released on 1992 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Goal was to fabricate a filter for removing particulates from hot gases; principal applications would be in advanced utility processes such as pressurized fluidized bed combustion or coal gasification combined cycle systems. Filters were made in two steps: make a ceramic fiber preform and coat it with SiC by chemical vapor infiltration (CVD). The most promising construction was felt/filament wound. Light, tough ceramic composite filters can be made; reinforcement by continuous fibers is needed to avoid brittleness. Direct metal to filter contact does not damage the top which simplifies installation. However, much of the filter surface of felt/filament wound structures is closed over by the CVD coating, and the surface is rough and subject to delamination. Recommendations are given for improving the filters.

Available in PDF, EPUB and Kindle. Book excerpt: Development work continues on the use of self-propagating high temperature synthesis (SHS) or combustion synthesis of inorganic materials (CSIM) to produce oxide based candle filter elements for hot gas clean-up (HGCU). Material combinations possessing suitable mechanical properties and corrosion resistance were identified and studied within the context of combustion synthesis. These combinations were selected to match the temperature, strength and corrosion resistance requirements of operation in pressurized, fluidized bed combustion (PFBC) environments. Filter permeability and capture efficiency was also examined. In addition, molding techniques to maximize oxygen diffusion/reaction completion and heating/re-heating cycles have been examined to reduce the cost of fabrication while maximizing simplicity.
