There are many kinds of gas burners. Next, the paper introduces several kinds of burners which are used in industrial boiler from the way of air supply.
1. Natural air burner: according to the shape of the furnace, circular or rectangular burner can be selected. The low-pressure burner flows out through the fire hole on the pipe and premixes with the air.
2. The ejector burner: variety, according to the combustion mode, it has some air premixed Bunsen premixed combustion mode and air flameless combustion mode, medium can be used in the air, also can be a certain pressure of gas, however, if the media are using the air blast device were required.
3. Blast burner: this type of burner generally consists of a distributor, a gas distributor, and a fire path.There are many kinds, but the ones that are commonly used are swirling and flowing.The air distributor of this kind of burner is basically similar to that of fuel oil burner. The basic types of fuel gas diverter are generally divided into single tube type and multi-tube type. The structure is simple, and the flame characteristics formed by combustion are similar to those of general swirl and direct flow fuel burner.
4. Imported gas burner: this burner is generally composed of three parts, namely, gas system, air supply system and control system.The main function of the gas system is to supply the gas needed for combustion.The air supply system provides the air needed for combustion.The control system is used to make the burner work according to the prescribed procedure.
