Cement rotary kiln burner manufacturer
The rotary kiln pulverized coal burner has been developed from a single duct to three ducts, four ducts and five ducts for burning more than two fuels. The more air ducts, the better the performance, but the more complex the structure, the greater the quality, the higher the cost, and the easier it is to bend and deform during use. Chinese rotary kiln burner manufacturers see the effect of coal and air mixing. The burners can be divided into swirling and splitting. The split four-channel burner channel is divided into external axial air, coal air, and internal shaft. Flowing wind and internal swirling wind, of which the outer axial flow is jetted axially, and the air duct is continuously formed. Because the split burner divides the coal wind into four jets, the pulverized coal is sprayed unevenly in the circumferential direction. The rotary kiln burner has a certain gap with the swirling type in terms of flame integrity, and it increases the wear of the coal air passage.
