Classification of gas burners there are many types of gas burners and different classification methods. It is difficult to use a classification method to reflect the characteristics of burners. This paper introduces several common classification methods: classification according to combustion method.
Diffusion burner: the air required for combustion is not mixed with gas in advance, and the primary air coefficient is 1 = 0; Atmospheric burner: part of the air required for combustion is mixed with gas in advance, and the primary air coefficient is 1 = 0.2 ~ 0.8; Thoroughly premixed burner: all air required for combustion is fully mixed with fuel gas in advance, and its primary air coefficient is 1 = 1.05 ~ 1.10
According to the air supply method, the ejector burner is classified: the air is sucked by the gas jet or the gas is sucked by the air jet; Natural air supply burner: the negative pressure in the furnace sucks air into the organization for combustion; Blast burner: use blast equipment to send air into the furnace to organize combustion.
Pure gas burner classified by fuel: gas fuel combined burner: gas or fuel gas pulverized coal combined burner can be used simultaneously or separately: submerged burner and high-speed burner can be used simultaneously or separately to burn gas or coal according to special functions.
