correct fuel air ratio

proper ignition temperature

02 to support combustion

all the three above

all the fuel burns instantaneously producing high energy release

fuel burns with less air

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
