Boiler Combustion. This Page is information from Cleaver-Brooks. less than 100 MMBtu/hr. Reducing the flame temperature decreases the radiant heat transfer from the flame and could lower boiler efficiency. The efficiency loss due to the lower flame temperatures can be partially offset by utilizing external components, such as an economizer

2020-3-25 · The loss gets less as excess air is added, reaches a minimum and then increases as still more excess air is added. Thus there is only one quantity of excess air which will give lower loss for the combustion of a particular fuel. For bituminous coal 15.5 % excess air is optimum requirement for Coal Combustion.
