automatic ignition coal powder burner

Pulverised Coal Burners High Output Burners Coal Ignition

First, coal is crushed and broken down into a powder, and the finer the powder, the more rapid the ignition. This powder is then dried and heated with an air heater for more effective burning. Then the pulverised coal is blown into the burner, spreading throughout it to increase the area of ignition inside the combustion chamber.

Ignition Temperature - an overview ScienceDirect Topics

Ignition temperature of coal and other dust is not affected by particle size. A big difference is made by the way coal dust comes in contact with a heat source. Thus, layered powder of coal can ignite at a much lower temperature (160°C approx.), whereas a cloud of coal dust will need 450–650°C to ignite. Table 23.7 shows some relevant data [5].
