Intermittent Combustion and Boiler Efficiency
Efficiency reduction due to intermittent boiler operation
Intermittent Combustion and Boiler Efficiency
Boiler combustion efficiency is reduced by intermittent operation due to:
- Energy loss in the flue gas - either by unburned fuel with the excess of fuel or by heating more air than necessary with the excess of air
- Radiation and convection loss from the exterior surface of the boiler
Energy loss due to radiation and convection increases with intermittent operation and reduced combustion time.
