Is Your Boiler Operating Efficiently? - Michaels Energy
The air to fuel ratio used for combustion has a major effect on the efficiency of the boiler. If the mixture is too rich (e.g. there is insufficient combustion air for the fuel flow) then some of the unburned fuel will leave the boiler through the exhaust flue. If the mixture is too lean (e.g. too much combustion air) then excessive air will
