Combustor and gas equipment

Abstract

The invention discloses a burner and gas equipment. The combustor comprises a combustion main body, an air inlet assembly, an air inlet assembly and a premixer, the combustion main body forms a first combustion chamber and a second combustion chamber and is used for heating the temperature in the first combustion chamber to a preset temperature, and the second combustion chamber is provided with a smoke outlet; the gas inlet assembly is used for introducing fuel gas; the air inlet assembly is used for introducing air into the first combustion chamber; a mixing cavity is formed in the premixer, the mixing cavity communicates with the air inlet assembly and the smoke outlet and conducts mixing, and mixed gas is jetted into the second combustion chamber so that high-temperature air combustion can be conducted in the second combustion chamber. According to the invention, fuel gas provided by the gas inlet assembly entrains primary air to the first combustion chamber and is ignited; the air inlet assembly sucks in secondary air, and the combustion main body combusts to generate high-temperature flue gas; after the premixer mixes the fuel gas and the flue gas at the flue gas outlet, the mixed gas is jetted to the second combustion chamber, an entrainment effect is generated, and the purpose of high-temperature air combustion is achieved.

Description

technical field [0001] The invention relates to the technical field of high temperature air combustion, in particular to a burner and gas equipment. Background technique [0002] High temperature air combustion technology is a mild combustion mode under low oxygen dilution conditions, also known as MILD combustion. Its main combustion characteristics are: low reaction rate, less local heat release, uniform heat flow distribution, low combustion peak temperature, and low noise. Because the MILD combustion temperature field is more uniform, the combustion peak temperature is low, and the generation of thermal nitrogen oxides is reduced. Compared with the ordinary combustion method, the emission of pollutants NOx and CO can be greatly reduced. [0003] Although high-temperature air combustion has many advantages mentioned above, it is currently an industrial application and not used in daily life. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention i...
