Understanding Fuel Savings In the Boiler Room

boiler efficiency by 4% to 6%. Using an air heater to raise the com-bustion air temperature is commonplace with utility boilers but is almost never done with packaged boilers. The nec-essary ductwork is expensive and can affect the low-NO. x. performance of the Boiler owners often cannot operate a boiler if the emissions are out of compliance.
