Pulverized coal-fired boilers may run with 20 percent excess air. with the stoichiometric air-fuel ratio, known as the perfect or ideal fuel ratio, the stoichiometric
Combustion – E Instruments
amounts of fuel and air (fuel/air ratio) are mixed for the correct amount of time .. In coal and wood fired boilers, ash is normally a by-product of combustion that

Normally the unburned in bottom ash in the pulverised fuel firing are higher sized air to secondary air ratios; Excess air at the burner/furnace and distribution of air Keep an optimal excess air level, generally about 20% in a coal fired boiler
-
Air is required when burning any fossil fuel. For coal, the ratio by weight of air to fuel is about 12. For a high heat release rate, therefore, a vast amount of air must
-
air/fuel stoichiometric ratio of 0.76 was about 33 percent, but it was accompanied by a reduction in applied NOx-control techniques for coal-fired boilers (2-4).
