The invention discloses an efficient and clean combustion method for improving heat efficiency of an internal combustion engine. A new combustion chamber is arranged on the basis of an aluminum alloy combustion chamber of an original all-aluminum alloy engine. An original cooling system, an original lubricating system, a high-quality aluminum alloy heat dissipation material and a preferable heat insulation material are combined into a whole to be made into a new air cylinder cover or a new piston. Combination of a new piston and a new cylinder cover into a new combustion chamber at a compression stroke top dead center is very important. Heat insulation of the new combustion chamber is very important, heat energy loss can be reduced, heat loads of a cooling system and a lubricating system are reduced, meanwhile, the adopted heat insulation material is resistant to high temperature, high pressure, rapid cooling and rapid heating and does not deform, and the new combustion chamber is resistant to high-temperature and high-pressure combustion. The new combustion chamber can improve the compression ratio. For example, when 20: 1 compression is stopped, the highest temperature is set to be 1000-1200 DEG C or above, 200 mpa oil is sprayed into the new combustion chamber at 5 DEG C before the top dead center of the compression stroke, and an oil supply combustion method of the new combustion chamber for evaporation and vaporization mixed combustion is instantly formed, so that advanced power circulation with ultrahigh heat efficiency, efficient clean emission and ultrahigh power density is achieved.

This invention discloses a co-firing biomass gas burner and method, belonging to the technical field of combustion equipment. The burner includes a central duct, an inner secondary duct, and an outer secondary duct, coaxially arranged from the inside out. A pulverized coal concentrator is installed inside the central duct, and its outlet end has a slitted blunt body structure with a central through-hole and an axial slit, used to form a graded pulverized coal gas flow. The biomass gas pipeline is equipped with a mechanical tar reduction structure based on temperature detection and flow rate regulation. Through the cooperation of the pulverized coal concentrator, the slitted blunt body, the secondary air swirl blades, and the guide plate, a series of primary and secondary recirculation zones are formed within the burner, achieving zoned mixing and graded combustion of pulverized coal and biomass gas. This invention solves the technical problems of incomplete co-firing, tar blockage, and low-NOx combustion in existing technologies, improving combustion efficiency, stable combustion performance, and reducing pollutant emissions.
