Power generating method of carbon-molecule gasification combustion boiler

摘要

A power generating method of Carbon-molecule gasification combustion, the method comprising the following main processes: taking coal with desulfurizing agent, and first conducting desulphuration and gasification in a molecular gasifier to produce clean coal gas; mixing hot coal gas and low excess air for combustion in the furnace of a boiler; conducting coke refining and dust removal according to coal quality and demand; after heat transfer via the heated surface of the boiler, emitting high temperature flue gas complying with the standard from the chimney; and the vapor generated by the boiler drives a steam turbine to generate power. The gasification method can be applied to a power generating system of a gas engine and a gas turbine to produce desired cooling coal gas, and can also produce chemical feed gas. The method has wide applicability and a simple process, is safe to operate and is environmentally friendly and energy saving.
