Abstract
The utility model relates to a superconducting flue gas waste heat recovery combustion-supporting system. A waste heat recovery device is installed on a flue gas passage, and the waste heat recovery device enables a pipeline and a combustion air connector of a combustion apparatus to be connected. High pressure combustion air is conducted into the waste heat recovery device, and is transmitted into the combustion apparatus to be used for auxiliary combustion after being heated. The superconducting flue gas waste heat recovery combustion-supporting system has the advantages that the high pressure combustion air is heated by the waste heat recovery device, and then is conveyed into the combustion apparatus for supporting the combustion. Thus, waste heat inside a furnace flue gas emission passage can be effectively utilized for heating the combustion air. Therefore, the combustion apparatus is easy to light, the combustion is complete and thermal pollution can be effectively reduced.
