This report presents the results of a feasibility study for the development of an innovative Pulsed Atmospheric Fluidized Bed Combustion (PAFBC) technology intended to expand coal utilization within the residential, commercial, and small industrial sectors of the economy. The analysis indicates that a coal-based technology that provides competitive levels of cost, performance, and reliability at the 1000 to 10,000 PPH steam can displace as much as 2.5 Quads of gas and oil within the residential, commercial, and light industrial sectors. In the industrial sector, systems from 10,000 to 50,000 PPH steam can displace another 1.1 Quads of energy. 41 refs., 28 figs., 19 tabs.
