When considering boiler energy savings, invariably the discussion involves the topic of boiler efficiency. The boiler suppliers and sales personnel will often cite various numbers, like the boiler has a thermal efficiency of 85%, combustion efficiency of 87%, a boiler efficiency of 80%, and a fuel-to-steam efficiency of 83%. Typically, 1.) Thermal efficiency reflects how well the boiler vessel transfers heat. The figure usually excludes radiation and convection losses. 2.) Combustion efficiency typically indicates the ability of the burner to use fuel completely without generating carbon monoxide or leaving hydrocarbons unburned. 3.) Boiler efficiency could mean almost anything. Any fuel-use figure must compare energy put into the boiler with energy coming out. 4.) \"Fuel to steam efficiency\" is accepted as a true input/output value.

The boiler suppliers and sales personnel will often cite various numbers, like the boiler has a thermal efficiency of 85%, combustion efficiency of 87%, a boiler efficiency of 80%, and a fuel-to-steam efficiency of 83%.
Typically,
1.) Thermal efficiency reflects how well the boiler vessel transfers heat. The figure usually excludes radiation and convection losses.
2.) Combustion efficiency typically indicates the ability of the burner to use fuel completely without generating carbon monoxide or leaving hydrocarbons unburned.
3.) Boiler efficiency could mean almost anything. Any fuel-use figure must compare energy put into the boiler with energy coming out.
4.) "Fuel to steam efficiency" is accepted as a true input/output value.
