Curtiss-Wright Corp. is building a 13 Mw pilot plant at Wood-Ridge,N.J., that will test the feasibility of combining fluidized-bed coal combustion technology with a gas turbine to generate electricity. The plant, which is one of the first stages of a $29 million contract awarded by ERDA, ill be designed by Stone and Webster Engineering Corp. and completed in 1980. According to S. Moskowitz (Curtiss-Wright), the plant will burn crushed coal in a bed of dolomite that is pressurized to 10 atm. The pressurization will enable the combustion gases to power the gas turbine which, when combined with a steam turbine to run electric generators, will increase the efficiency to 40%. The pressurized operation offers the prospect of lower nitrogen oxides emissions, lower sorbent requirements, and smaller equipment than conventional coal-fired boilers. Potential capital and operating cost savings could be 10-15%. The status of research on atmospheric and pressurized fluidized beds and the control of sulfur dioxide emissions from pressurized beds are discussed.
