ABSTRACT:
Heat energy is generated from low-grade alkaline fuels (such as manure and lignite) in a gasifier-combustor system. The fuel is gasified at a temperature of less than 900.degree. C. in a circulating fluidized bed gasifier comprising a first cyclone separator. The gas leaving the first separator is conveyed to a second cyclone separator. The gas leaving the second separator is burned in a boiler at a temperature of at least 900.degree. C. Alkaline containing material is removed and collected from the gasifier, the first and second separators, the boiler and a filter before the gas is vented to the atmosphere.
