Burner, as the indispensable equipment in the rotary kiln calcining process, usually has the three types of gas, coal, gas coal. For the coal combustion equipment, pulverized burner has several steps.
1, pulverized coal and air mixing, the rotary kiln is a turbulent diffusion flame; the mixing process of combustion is the main process, therefore, diffusion rate controls the burning rate.
2, pulverized coal and air are heated to the ignition temperature. In the process of heating coal, volatile is first introduced and ignition temperature of pulverized coal is actually a temperature ofvolatile.
3, pulverized coal in the volatile burns and heat energy that is released is used to maintain the next stage of coke burning. If the coal volatile content is too low, heat released by the volatile combustion is not enough to sustain the next stage of combustion.
4, after coal burning ember, coal in coke burning marks the end of the entire combustion process.
Above four stages is the whole burning process of pulverized coal burner of rotary kiln. This process is deceptively simple, but involves a lot of things, such as the length of flame, the high and low flame temperature, the size of the flame, etc. In the process of operation, it will also need professional personnel management.
