Water-cooling type petroleum coke powder burner

Abstract

The invention discloses a water-cooling type petroleum coke powder burner which comprises a gun body. The gun body comprises a body tube. The front end of the body tube is sealed through a first sealing cover. The tail end of the body tube is sealed through a second sealing cover. A circulation water pipe, an atomized gas inner tube and gas-powder mixing tubes are sequentially arranged on the inner side of the body tube. A water inlet passage is arranged between the circulation water pipe and the body tube. A drain passage is arranged between the circulation water pipe and the atomized gas inner tube. A feed passage is arranged between the gas-powder mixing tubes. The tail end of the atomized gas inner tube and tail ends of the gas-powder mixing tubes penetrate through the second sealing cover and then are connected with a gun head. A gun cap is arranged on the gun head. The water-cooling type petroleum coke powder burner is reasonable in structural design, capable of making coke powder to combust sufficiently, improves the coke powder utilization rate, is low in consumption rate, and can reduce melting furnace burning damage degree. Moreover, the gun cap of the gun head does not coke and is long in service life.

Description

technical field [0001] The invention relates to a combustion device for an industrial kiln, in particular to a water-cooled petroleum coke powder burner. Background technique [0002] The glass industry is a high-energy-consuming industry, and the glass melting furnace is the equipment that consumes the most energy in the glass production line. At present, the fuels used in the glass field include heavy oil, coal tar, natural gas, petroleum coke, etc. With the rising price of oil and natural gas, since petroleum coke powder is the final product in the process of petroleum refining, the existing physical properties of petroleum In recent years, the use of petroleum coke instead of oil and natural gas as the fuel for glass melting furnaces has attracted more and more attention and popularity. [0003] Because the burner used in the current petroleum coke system is only a straight cylinder in which the inner tube uses the gas powder mixture and the outer tube uses the atomized...

AI Technical Summary

Problems solved by technology

[0003] Because the burner used in the current petroleum coke system is only a straight cylinder in which the inner tube uses gas powder mixture and the outer tube uses atomized gas, the tip and cap of this type of burner are easy to coke, which will damage the furnace It is relatively large and needs to be cleaned every few hours. Its service life is very short, only three to six months, and the wear and tear is serious

Therefore, the consumption rate of the burner of the current kiln is relatively high, and the labor cost is relatively high, and the burning loss of the furnace is relatively heavy.
