Production of clean, cost-competitive electric power from coal requires advances in combustion and power conversion technology. One promising approach to improved power cycle efficiency involves application of a Pressurized Fluidized-bed (PFB) Combustor for combustion of high sulfur coal in the presence of a sulfur sorbent material. Bed temperature is controlled to maintain the bed temperature below 1750/sup 0/F by removing heat from the PFB with heat exchanger tubes using a portion of incoming compressed air as coolant, while the balance of compressed air is used for combustion. The coolant air is heated substantially to bed gas temperature and mixes with the products of combustion after they are cleaned of particulates but prior to entering a gas turbine expander. The reduced percentage of turbine gas directly involved in coal combustion results in substantially less gas to be cleaned of particulates. The most obvious application of the PFB combustor to commercial, base load power production is in a combined-cycle system. The PFB combustor, in this concept, would supply energy to a gas turbine-generation unit, and a waste heat boiler at the exit of the gas turbine system would supply steam for a steam turbine-generator unit. A simplified flow diagram for the air-cooled PFB combined cycle system is shown.
