Abstract
The invention provides a method for generating power by combusting and decomposing a coal ash reproducing fuel gas by using a thermal power generation waste gas as a plasma torch inert gas source. The method is characterized in that a passage is additionally arranged beside a flue for a thermal power plant to discharge the waste gas; the waste gas obtained after the power generation of the coal gas is directly connected with a plasma torch inert gas inlet via the passage; a plasma torch is fixed in a high pressure combustion chamber; machined ultrathin coal ash discharged from the power plant is filled in the high pressure combustion chamber; after the plasma torch is electrified, the machined ultrathin coal ash is gasified by a high pressure flame sprayed by the plasma torch to generate smaller combustible gaseous particles; meanwhile, the gaseous particle gas can push a small-sized power generator to operate; and after the combustible gaseous particles enter a gas storage tank, the combustible gaseous particles in the gas storage tank can be reused for greater power generation.
