· Oxidation is an exothermic reaction which causes the temperature of the coal stack to rise gradually. As the pile exceeds approximately 800C ignition can occur. Spontaneous combustion of the coal depends on many factors and critical among these is the type, age and composition of coal. 2) Coal Conveying
Pulverized coal is typically used to fire a boiler. Under certain conditions regarding temperature, filling level, moisture content etc. smouldering fires may originate in coal bunkers and cause the danger of open fires or even dust explosions. Smouldering fires are followed by an increase in CO concentration in the headspace area of the bunker.
