Industry uses large quantities of oil and gas for raising steam, representing a candidate market for increased coal use. The high capital cost of coal-fired boilers has hindered the conversion from oil to coal in industry. Boiler cost could be reduced if they could be shop-fabricated in large steaming capacities. Pressurized fluidized bed boilers appear to offer a means by which coal-fired units of up to 200,000 lb/h capacity could be shop-fabricated. Both gas turbines and steam turbines could be used to supply power for pressurizing the furnace. A preliminary cost analysis indicated that a pressurized fluid bed packaged boiler would offer considerable savings.
