Several advanced, coal and biomass-based combustion turbine power generation technologies using solid fuels (IGCC, PFBC, Topping-PFBC, HIPPS) are currently under development and demonstration. A key developing technology in these power generation systems is the hot gas filter. These power generation technologies must utilize highly reliable and efficient hot gas filter systems if their full thermal efficiency and cost potential is to be realized. This paper reviews the recent test and design progress made by Westinghouse in the development and demonstration of hot gas ceramic barrier filters toward the goal of reliability. The objective of this work is to develop and qualify, through analysis and testing, practical hot gas ceramic barrier filter systems that meet the performance and operational requirements for these applications.

Power Generation Systems

Several advanced, coal- and biomass-based combustion turbine power generation technologies are currently under development and demonstration. A key technology component in these power generation systems is the hot gas filter. These power generation technologies must utilize highly reliable and efficient hot gas filter systems to protect the turbine and to meet environmental constraints if their full thermal efficiency and cost potential is to be realized. Siemens Westinghouse Power Corporation (SWPC) has developed a hot gas filter system to near-commercial status for large-scale power generation applications. This paper reviews recent progress made by SWPC in hot gas filter test development programs and in major demonstration programs. Two advanced hot gas filter concepts, the “Inverted Candle” and the “Sheet Filter”, having the potential for superior reliability are also described.

Advanced, coal- and biomass-based gas turbine power generation technologies (IGCC, PFBC, PCFBC, HIPPS) are currently under development and demonstration. Efforts at the Siemens Westinghouse Power Corporation (SWPC) have been focused on the development and commercialization of hot gas filter systems as an enabling technology for power generation. As part of the commercialization 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 an extended accelerated filter life testing program. This paper reviews SWPC’s material and component assessment efforts, identifying the performance, stability, and life of porous oxide- and nonoxide-based ceramic, as well as metal and intermetallic filters used in advanced, high temperature, coal combustion systems.

Indirect firing of combined Brayton and Rankine cycles has been considered as a means of utilizing solid fuels such as wood or coal for power generation. Combined cycles utilizing indirect firing offer potentially higher efficiencies than conventional direct fired Rankine cycles. Many thermodynamic alternatives exist for indirect firing; however, technical, economic, and commercial barriers must be overcome for each of these alternatives. This paper reviews several of the options for indirect fired cycles and considers the factors affecting their application to power generation systems.

Power Generation Systems

Numerous attempts have been made during the past two decades to develop advanced power generation systems which could burn coal or coal-derived fuels both economically and in an environmentally acceptable manner. Although much valuable technology has been derived from these programs, commercially viable power generation alternatives have not yet appeared. One prospective way to expedite the commercialization of advanced coal-fired power systems is to meld the latest gas turbine technology with the emerging technology for producing slurries of water and ultra clean coal. This paper describes a DOE-sponsored program to identify the most attractive gas turbine power system that can operate on slurry fuels. The approach is to use slurries produced from finely ground (<10 microns) coal powder from which most of the ash and sulfur has been removed. The gas turbines will incorporate a rich-burn, quick-quench combustor to minimize conversion of fuel-bound nitrogen to NOx, advanced single crystal alloys with improved hot corrosion resistance and strength, advanced metallic and ceramic coatings with improved erosion and corrosion resistance, and more effective hot section cooling. Two different power plant configurations are covered: a large (nominally 400 MW) combined cycle plant designed for base load applications; and a small (nominally 12 MW) simple-cycle plant designed for peaking, industrial, and cogeneration applications.

The Military

Electric power is the most common source of power for many portable devices used in outdoor recreation, emergency scenarios, and military applications. Batteries that have limitations regarding power and energy are currently meeting the power demand for most of these devices. There is a search to use alternative power sources for portable energy needs. This search has mostly been researched particularly for the military to satisfy functions necessary for soldiers. However, any alternative that would provide electricity in an efficient and timely manner is useful in many applications beyond the military. The feasibility of man-portable power generation systems using thermal energy from any kind of fuels needs to be studied further, to understand if they are truly an option for situations where batteries are currently used. In this study, the feasibility of fueled power systems is investigated. Commercially available small power systems show that they are not small enough to satisfy the definition of man-portable power system. However, power systems working on an internal combustion engine show to be a better option when compared to batteries and fuel cells.

The reliability of switching elements of PECs is still below expectations and is a major contributor to the downtime of renewable power generation systems. Conventional technology based elements such as Silicon Insulated Gate Bipolar Transistors (IGBTs) operate as switching components in PECs. Recent topological improvements have led to new devices called Silicon Carbide (SiC) MOSFETs which, are also being used as switching elements for PECs. <span style="color: black; mso-themecolor: text1;">This paper presents detailed investigations into the performance of those switching devices with a focus on their reliability and thermal characteristics. Namely, trench gate NPT, FS IGBT topologies and SiC MOSFET are firstly modelled using 3-D multi-physics finite element modelling to gain clear understanding of their thermal behaviour. Subsequently, modelling outcomes are verified by using those devices as switching elements in operational boost converters. The purposely-developed test setups are utilised to critically assess the performances of those switching devices under different loading and environmental conditions.
