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 draft assembly and a premixer, a first combustion chamber and a second combustion chamber are formed in the combustion main body, and the combustion main body is used for heating the temperature in the first combustion chamber to a preset temperature; the gas inlet assembly is used for introducing fuel gas into the first combustion chamber; the air draft assembly is used for introducing air into the first combustion chamber; and the premixer is used for introducing fuel gas and air, mixing the fuel gas and the air, and spraying mixed gas into the second combustion chamber, so that high-temperature air combustion is performed in the second combustion chamber. According to the invention, fuel gas provided by the gas inlet assembly entrains primary air and is ignited; the air draft assembly sucks secondary air into the first combustion chamber to generate high-temperature flue gas; and the premixer sprays mixed gas to the second combustion chamber, so that the mixed gas is matched with the high-temperature flue gas to generate an entrainment effect, the high-temperature flue gas flows back, 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 features 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 ordinary combustion methods, it can greatly reduce the emissions of pollutants NOx and CO. [0003] Although high-temperature air combustion has the above-mentioned many advantages, it is currently used in industrial applications and is not used in daily life.
