Air Fuel Ratio In Boiler

THE IMPACT OF EXCESS AIR ON EFFICIENCY

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

The KN Boiler limits the turndown to keep the pressure drop thru the gas regulator well within its ability to provide precise gas flow. Also, the KN is Air/Fuel coupled entirely thru its turndown range. Any variation in weight flow of air through the boiler causes the gas flow to respond in a manner that correctly maintains the Air/Fuel ratio.
