The main objective of this program is to evaluate the commercial potential of a power generating concept that includes the pressurized, fluidized bed combustion of coal in conjunction with a combined gas-steam turbine cycle. The capability to burn high-sulfur coal in an environmentally acceptable manner is a requirement. The program involves conceptual commercial design, supporting experimental work, and the design, construction and operation of a PFB pilot plant which can be used to evaluate the commercial concept. The SGT/PFB Technology Unit was designed, procured, erected at the Curtiss-Wright Plant in Wood-Ridge, New Jersey, and placed in operation in 1977. Parametric performance evaluation tests were conducted and completed in July 1978. The secondary gas cleanup system was then modified to include three inertial-type units in series. In mid-1979 the test program was again initiated with the following objectives: Continued evaluation of candidate heat exchanger tube materials to determine the rate data for tube life prediction; evaluation of candidate turbine blade and vane materials and coatings to determine rate data for life prediction; evaluation of the modified hot gas cleanup system; conduct particulate grab sample tests throughout the test to determine grain loading and particle size distribution; and gas turbine operation for 1000 h while burning high sulfur coal in the PFB combustor. Total operating time to date is 3378 hours which includes 2681 hours burning coal and 1205 hours total turbine engine operation. Significant performance and operational milestones have been accomplished and are reported. (LCL)
