Combustion high CO - Boiler and Pressure Vessel

CO is incomplete combustion. Your fuel started to burn, but before the carbon was converted to CO2 by complete combustion, it was "quenched" so that it ceased to burn. Quenching can occur when burning fuel enters the upper furnace or the boiler tube/superheater banks and the gasses cool off to a point that they won't support any more combustion

Understanding Combustion Efficiency and Combustion Equations

Understanding Combustion Efficiency Combustion efficiency is a measurement of how well the fuel being burned is being utilized in the combustion process. This is different from the efficiency number produced on the analyzer, which is reflective of the total amount of heat available from the fuel minus the losses from the gasses going up the stack.
