Coal gasification - Wikipedia

8/7/2021 · For proper combustion of fuel inside the boiler, a certain amount of oxygen is required. If too little air is present, the carbon in the fuel will be oxidized, making carbon monoxide. This causes less heat to release because the fuel isn't completely burned, which lowers fuel use efficiency.

How to Destroy a Boiler -- Part 1

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and will continue to produce some heat.
