2018-8-5 · EXCESS AIR AND BOILER EFFICIENCY In theory, to have the most efficient combustion in any combustion process, the quantity of fuel and air would be in a perfect ratio to provide perfect combustion with no unused fuel or air. This type of theoretical perfect combustion is called stoichiometric combustion. In practice, however, for safety and
Get a Quote2020-9-12 · The stoichiometric air-fuel ratio is an important parameter of fuels. When designing an engine for a particular fuel, it's important to know how much air is needed to completely burn a certain amount of fuel. This article describes this ratio and presents an easy way to calculate it when the composition of a fuel is known. How air-fuel ratio can be diagnosed and monitored with the help of air
