Atmospheric fluidized bed coal combustor for cogeneration

Conference ·
OSTI ID:6553472

A coal-fired fluidized bed system designed to supply electricity and process heat for industrial applications is being developed. This concept, featuring clean coal technology and energy conservation, is designed to meet the urgent national goal of converting American industry to coal to save dwindling supplies of oil and gas. Sixty percent of all industrial process heat requirements could be served by this technology, yielding oil and gas savings equivalent to more than half our total oil imports. In this cycle, air is heated to 815/sup 0/C (1500/sup 0/F) in the fluidized bed combustor and passed through a gas turbine to produce electricity. Exhaust air from the gas turbine is available as industrial process heat at temperatures ranging from 260 to 540/sup 0/C (500 to 1000/sup 0/F), depending on the energy requirements of the industrial facility. Research and development activities have been carried out on the coal feed system, fluidization, heat transfer, and corrosion/erosion of in-bed tubes. A 5 x 10/sup 6/ Btu/h technology test unit is planned.
