The US Department of Energy sponsored this program to develop and test the Granular Bed Filter (GBF) as part of the overall program to develop coal-fired, pressurized fluidized-bed combustors to be used in combined-cycle power generating systems. In these systems a portion of the electricity is generated using a gas turbine driven by the high-temperature, high-pressure combustion gas. A hot gas cleanup train, such as the Granular Bed Filter, must be installed before the gas turbine to prevent erosion of turbine materials and deposition of particulate within the turbine. Meeting New Source Performance Standards (NSPS) with this filter is also required to eliminate need for post-turbine particulate removal. Furthermore, it has also been shown that alkali (sodium and potassium) in trace amounts can harm gas turbine materials. The GBF was evaluated for removal of these contaminants. The purpose of this work was to obtain information on the operational and economic feasibility of the Granular Bed Filter when applied to a pressurized fluidized-bed combustor (PFBC) as a high-temperature, high-pressure particle control device. In this program, experimental data was obtained on the design and operational life of critical components, an experimental sequence was conducted on a subpilot-scale GBF test module, and an update of a commercial-scale design was completed based on experimental data. Results are discussed. 60 figs., 23 tabs.
