Vertical Composite Boiler Energy Efficiency

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.

Oct 24, 2012 · The boiler efficiency difference is not a huge fuel savings. 85% - 95% does not make a real difference. The efficiencies are rated at 120f return temp and 140 supply temp with proper flow rates. If the actual operation is not 120f - 140f temps and the flow rate is not the same as tested the efficiency will not be the same as reported.

Commercial Boilers | Products - ENERGY STAR

ENERGY STAR certified commercial boilers have a thermal efficiency of ≥ 94.0% and a turndown ratio of 5:1. Thermal efficiency is the ratio of the heat energy (Btu/hr) absorbed by the water to the heat energy available in the fuel burned. The turndown ratio is the boiler's maximum nameplate firing rate (Btu/hr) divided by its lowest
