Swirl Burner

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of two advanced coal-fired power systems and several high-temperature, high-pressure gas filtration systems. The PSDF was designed at sufficient scale so that advanced power systems and components could be tested in an integrated fashion to provide data for commercial scale-up. The PSDF is funded by the U.S. Department of Energy, Electric Power Research Institute, Southern Company Services, Foster Wheeler, Kellogg Brown & Root, Siemens Westinghouse Power Corporation (SWPC), Combustion Power Company and Peabody Holding Company. The PSDF is configured into two separate test trains: the Kellogg Brown & Root (KBR) transport reactor train and the Foster Wheeler Advanced Pressurized Fluidized Bed Combustor (APFBC) train. The APFBC train also includes a topping combustor and gas turbine generator to produce electrical power. The APFBC train is designed for long term testing of the filtration systems and the assessment of control and integration issues associated with the APFBC system. The Siemens Westinghouse Multi-Annular Swirl Burner (MASB) has been developed as the topping combustor for the APFBC application. In this application, the combustion air is vitiated air, a depleted oxygen (10 to 16 vol %), high temperature (1200 to 1400°F) (650 to 760°C) gas stream, which is the exhaust gas from the fluidized bed combustion of solid fuel. The topping combustor fuel is a synthetic low-Btu fuel gas at high temperature (1200 to 1400°F) (650 to 760°C) generated by gasifying coal in the APFBC. The hot MASB combusted gas is expanded through a gas turbine for power generation. Commissioning of the MASB began in January, 1998. Over 400 hours of operation have been accumulated through November 1999. Several improvements have been designed and installed during commissioning. This paper explains the design basis of the MASB, describes design changes implemented at the PSDF and reviews the operational experience of the MASB at the PSDF.

The Power Systems Development Facility (PSDF) is a Department of Energy (DOE) sponsored engineering scale demonstration of two advanced coal-fired power systems. Particulate cleanup is achieved by several High Temperature, High Pressure (HTHP) gas filtration systems. The PSDF was designed at sufficient scale so that advanced power systems and components could be tested in an integrated fashion to provide confidence and data for commercial scale-up. This paper provides an operations summary of a Siemens-Westinghouse Particulate Control Device (PCD) filtering combustion gas from a Kellogg, Brown, and Root (KBR) transport reactor located at the PSDF. The transport reactor is an advanced circulating fluidized bed reactor designed to operate as either a combustor or a gasifier. Particulate cleanup is achieved by using one of two PCDs, located downstream of the transport reactor. As of the end of 1998, the transport reactor has operated on coal as a combustor for over 3500 h. To date, filter elements from 3M, Blasch, Coors, Allied Signal (DuPont), IF&P, McDermott, Pall, Schumacher, and Specific Surface have been tested up to 1400 °F in the Siemens-Westinghouse PCD. The PSDF has a unique capability for the collection of samples of suspended dust entering and exiting the PCD with Southern Research Institute’s (SRI) in-situ particulate sampling systems. These systems have operated successfully and have proven to be invaluable assets. Isokinetic samples using a batch sampler, a cascade impactor and a cyclone manifold have provided valuable data to support the operation of the transport reactor and the PCD. Southern Research Institute has also supported the PSDF by conducting filter element material testing. [S0742-4795(00)02203-1]

Hot Gas Filtration

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal-fired power systems and high-temperature, high-pressure gas filtration systems. The PSDF was designed at sufficient scale so that advanced power systems and components can be tested in an integrated fashion to provide data for commercial scale-up. The PSDF is funded by the U.S. Department of Energy, the Electric Power Research Institute, Southern Company Services, Kellogg Brown & Root, Inc. (KBR), Siemens-Westinghouse, and Peabody Energy. Gasification at the PSDF is based on KBR’s Transport Gasifier, which is an advanced circulating fluidized-bed gasifier. Hot gas filtration is a critical process in the gasification system to clean up the particulate matter before the synthesis gas (syngas) is fed to the turbine. A Siemens-Westinghouse particulate control device (PCD) is used for syngas cleanup. The PCD contains 91 candle-style filter elements. More than twenty types of filter elements, categorized as monolithic ceramic, composite ceramic, sintered-metal powder, and sintered-metal fiber, have been tested in the gasification environment at the PSDF. Up to January 2005, the longest exposure time for individual filters has been 5783 hours. The particulate loading in the clean syngas during most stable operating periods has been demonstrated to be consistently below 0.1 ppmw, which is the lower detection limit of Southern Research Institute’s sampling system. Safeguard devices (failsafes) have also been tested and developed at the PSDF. Failsafes are used to block the particulate leaking through the PCD in the case of filter element failure to eliminate damage to the turbine. Demonstration of reliable failsafes is a critical factor to the hot gas filtration technology. Several types of currently available failsafes and PSDF-developed failsafes have been tested in the PCD with gasification ash injection to simulate filter element leakage. A typical failsafe was also tested in a device equipped with a quick-open mechanism to simulate a complete filter failure during a test run operation. The testing showed promising results for certain types of failsafes. Further failsafe testing and better understanding of turbine requirements for particulate loading are needed to evaluate the PCD performance and increase readiness towards commercialization of the technology.

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal-fired power systems and high-temperature, high-pressure gas filtration systems that would be integral to an improved coal-fired power plant having efficiencies well over 40%, while exceeding all current emission standards for coal-fueled plants. The paper will describe such a plant before expanding the discussion on the operational experiences of the Kellogg Brown & Root, Inc. (KBR) Transport Reactor and the Siemens Westinghouse Power Corporation (SWPC) high-temperature gas filter system currently being demonstrated at the PSDF. A short survey of the process advantages (capital, operational, efficiency, and reliability) over current Integrated Gasification Combined Cycle (IGCC) plant designs, including hot gas clean-up, air-blown gasification, non-slagging gasifier operation and equipment commonality with existing pulverized coal power plants, will be highlighted; as will the potential of the power plant to be retrofitted in response to future carbon capture requirements.

The Exxon Research pressurized fluidized bed coal combustion pilot plant, known as the miniplant, has been in operation since 1974. Constructed under EPA contract, this facility operates at pressures to 10 atm, bed velocities to 10 ft/sec and temperatures to 1800 F. It can burn 400 lb of coal per hour and has operated for over 2500 test hours. Under a program sponsored by the U. S. Department of Energy, the Exxon pressurized fluidized bed coal combustion miniplant provided a test site and environment for the exposure of specimens of potential PFBCC fireside heat exchanger alloys and gas turbine materials. The intent of these PFBCC exposure tests is to compile a suitable engineering data base for the characterization of the corrosion/erosion behavior of a number of commercially available alloys when exposed to a pressurized fluidized bed coal combustion environment. These PFBCC exposures will provide corrosion/erosion data and comparisons of materials for application to advanced gas turbine/combined cycle type power systems using coal.

Swirl Burner

About 75% of the electric power generated by centralized power plants feeds the energy needs from the residential and commercial sectors. These power plants waste about 67% of primary energy as heat emitting 2 billion tons of CO2 per year in the process (∼ 38% of total US CO2 generated per year) [1]. A study conducted by the United States Department of Energy indicated that developing small-scale combined heat and power systems to serve the commercial and residential sectors could have a significant impact on both energy savings and CO2 emissions. However, systems of this scale historically suffer from low efficiencies for a variety of reasons. From a combustion perspective, at these small scales, few systems can achieve the balance between low emissions and high efficiencies due in part to the increasing sensitivity of the system to hydrodynamic and heat transfer effects. Addressing the hydrodynamic impact, the effects of downscaling on the flowfield evolution were studied on the low swirl burner (LSB) to understand if it could be adapted to systems at smaller scales. Utilizing particle image velocimetry (PIV), three different swirlers were studied ranging from 12 mm to 25.4 mm representing an output range of less than 1 kW to over 23 kW. Results have shown that the small-scale burners tested exhibited similar flowfield characteristics to their larger-scale counterparts in the non-reacting cases studied. Utilizing this data, as a proof of concept, a 14 mm diameter LSB with an output of 3.33 kW was developed for use in microturbine operating on a recuperated Brayton cycle. Emissions results from this burner proved the feasibility of the system at sufficiently lean mixtures. Furthermore, integration of the newly developed LSB into a can style combustor for a microturbine application was successfully completed and comfortably meet the stringent emissions targets. While the analysis of the non-reacting cases was successful, the reacting cases were less conclusive and further investigation is required to gain an understanding of the flowfield evolution which is the subject of future work.

Research has been conducted under United States Department of Energy (USDOE) Contract DE-AC21-86MC21023 to develop a new type of coal-fired, combined cycle, gas turbine-steam turbine plant for electric power generation. This new type of plant — called a 2nd Generation or Advanced Pressurized Fluidized Bed Combustion (APFB) plant — offers the promise of efficiencies greater than 48 percent (HHV) with both emissions and a cost of electricity that are significantly lower than those of conventional pulverized-coal-fired plants with scrubbers. In the 2nd Generation PFB plant coal is partially gasified in a pressurized fluidized bed reactor to produce a coal derived syngas and a char residue. The syngas fuels the gas turbine and the char fuels a pressurized circulating fluidized bed (PCFB) boiler that powers the steam turbine and supplies hot vitiated air for the combustion of the syngas. A conceptual design and an economic analysis was previously prepared for this plant, all based on the use of a Siemens Westinghouse W501F gas turbine with projected gasifier, PCFB boiler, and gas turbine topping combustor performance data. Having tested these components at a pilot plant scale and observed better than expected performance, the referenced conceptual design has been updated to reflect that test experience and to incorporate more advanced turbines e.g. a Siemens Westinghouse W501G gas turbine and a 2400 psig/1050°F/1050°F/2-1/2 in. Hg steam turbine. This paper presents the performance and economics of the updated plant design along with data on some alternative plant arrangements.

In the European Union by 2050, more than 80% of electricity should be generated using nongreenhousegases energy technology. Nuclear power systems share at present about 15% of the power market and thistechnology can be the backbone of a carbon-free European power system. Energy market transitions are similar to global pathways were analysed in the Intergovernmental Panel on Climate Change report. From a practical point of view currently, the most advanced and most effective technology for electricity generation is based on a gas turbine combined cycle. This technology in a normal way uses natural gas, synthesis gas from the coal gasification or crude oil processing products as the energy carriers but at the same time, such system emits sulphur oxides, nitrogen oxides, and CO2 to the environment. In thepresent paper, a thermodynamic analysis of environmentally friendly power plant with a high–temperature gas nuclear reactor and advanced configuration of gas turbine combined cycle technology is investigated. The presented analysis shows that it is possible to obtain for proposed thermalcycles an efficiency higher than 50% which is not only more than could be offered by traditional coal power plant but much more than can be proposed by any other nuclear technology.

High-temperature turbine technology (HTTT) when applied to the reheat-gas-turbine combined cycle (RHGT/CC) offers distinct advantages over the presently contemplated United States Department of Energy (DOE) HTTT simple-cycle gas-turbine combined cycle (SCGT/CC) being developed for gaseous fuel derived from coal. Specific improvements are: 1) higher combined-cycle efficiency, 2) higher specific output per unit of air flow, 3) less critical high-temperature nozzle-vane and rotating-blade surface area to be cooled, 4) less strategic high temperature metal material to be used, and 5) less overall cycle-cooling degradation allowing growth potential. New cooling techniques employing steam are required to accomplish these projections which necessitates advanced research and development and presently unavailable mathematical analytical approaches.
