Spontaneous Coal Combustion Part 1: A Burning Mystery ...
India has the largest concentration of coal fires, and it is estimated that 80% of those fires started due to spontaneous combustion. Indian coal fires were first documented in coal fields located in Raniganj back in 1865. In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over 100 years dating back to 1916.

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.

What is meant by pulverized coal? - AskingLot
2020-5-11 The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. As the coal gets crushed by the rolling action, the hot air dries it and
