Combustion of Coal by Gasification

抄録

Combustion of coal by gasification-transformation of coal into gas prior to combustion in a furnace-is an advantageous method of combustion especially for smoke-removal in cities and for utilization of low-quality coal, and can be applied for boilers, gas turbines and industrial furnaces. Gas producers for this purpose must have improved efficiencies and high capacities. Construction and test results of a continuously operating gas producer, which was test-built to verify this method, are described and it is shown that this producer can be operated at a gasification efficiency (hot gas base) 94% for a long period by employing an improved injection method of air and steam. And, experimental results and technical problems about combustion of low-quality coal by gasification method are also discussed.
