Steadily increasing energy requirements have spurred a search for new methods of generating energy from low-cost, abundant fuels. The development of a gas-turbine system equipped for the direct combustion of such fuels is now underway in the U.S. A one-megawatt pilot plant has been operating for over a year, using a fluidized bed to burn coal. The plant has also operated on wood waste and municipal solid waste as fuels. Methods have been developed for the suppression of noxious gases included among the combustion products, but there remain some problems with the removal of particulate matter from the exhaust gas prior to its entry into the turbine. A new high-temperature filter is being installed to alleviate these. A description of the one-megawatt pilot plant is provided, along with a discussion of operational results and mechanical problems and their solutions. A preliminary design for a full-scale plant is included.
