Spontaneous combustion is a phenomenon in which

Coal bursts into flame without any external ignition source but by itself due to gradual increase in temperature as a result of heat released by combination of oxygen with coal

Explosion in furnace

All the fuel burns instantaneously producing high energy release

Fuel burns with less air
