Demonstration of pulse combustion in an application for steam gasification. Comprehensive report to Congress, Clean coal technology program
In response to the PON, 33 proposals were received by DOE in May 1991. After evaluation, nine projects were selected for award. One of the nine projects selected for funding is a project proposed by ThermoChem, Inc. entitled ``Demonstration of Pulse Combustion in an Application for Steam Gasification of Coal`` (PCASGC). The PCASGC demonstration project involves the construction of a 428 ton/day (300 ton/day dry basis) fluidized bed, coal gasification unit. The gasifier will use indirect heating to provide the energy required for the steam-coal reaction occurring in the gasifier. The heat will be added to the gasifier by means of bundles of heat exchanger tubes submerged in the fluidized bed. The hot gas for the indirect heating will be generated by pulse combustion of a portion of the product gas, with the heat exchanger tubes acting as the resonance tubes for the pulse combustor. Pulse combustion increases heat transfer rate by a factor of 3 to 5, thus greatly reducing the heat transfer area required in the gasifier. The PCASGC Demonstration project will be constructed at Caballo Rojo, Inc.`s Caballo Rojo Mine, located south of Gillette, Wyoming. Coal from the Caballo Rojo Mine will provide the feed coal to the gasifier. The total project cost is $37,333,474. DOE`s share is $18,666,737. The cofunder is ThermoChem, whose share is $18,666,737. Operations are scheduled to begin in 1994, and the project is scheduled for completion in 1996.
