Abstract

The invention relates to the technical field of combustion equipment, in particular to a self-preheating temperature adjusting gas burner. The self-preheating temperature adjusting gas burner comprises a gas pipe, a primary air flowing guiding pipe and a secondary air flowing guiding pipe, a shell is internally provided with the primary air flowing guiding pipe, the primary air flowing guiding pipe is coaxially arranged on the outside of the gas pipe in a sleeving mode, and the secondary air flowing guiding pipe communicates with the gas outlet end of the gas pipe. According to the self-preheating temperature adjusting gas burner, the flame temperature is adjusted by controlling the air inlet amount of the secondary air flowing guiding pipe, meanwhile, secondary air and flue gas are mixed,the temperature of the flue gas is reduced, thus the flame temperature is adjustable, and heat carried by the flue gas can exchange with primary air, so that the primary air is more suitable for combustion supporting, meanwhile, the heat of the flue gas is reduced, the temperature of combustion supporting air is increased, and energy sources are saved.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a self-preheating and temperature-regulating gas burner. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition products will gradually accumulate in t...
