The adoption of coal-fired pressurized fluidized-bedThese include conventional and augmented cyclones; combined-cycle combustion systems by utilities for porous metal, fabric, and ceramic membrane filters; electric power generation depends to a large extent on the fixed-, continuously moving-, and fluidized-bed development of an efficient and economic cleanup system granular filters; electrostatic precipitators; as well as between the combustor and gas turbine. To accomplish several other novel separation devices. The results of tests particulate removal from a dust-laden gas stream, a of these devices are discussed in relation to pressurized number of separation devices have been developed. fluidized-bed combustion applications.
