Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Efficiency reduction due to intermittent boiler operation.
Boiler combustion efficiency is reduced by intermittent operation due to
Energy loss due to radiation and convection increases with intermittent operation and reduced combustion time as indicated in the diagram below:

Combustion gross and net calorific value. Minimum area in a boiler room. Classification of boilers according the ASME Boiler and Pressure Vessel Code. Optimizing boilers efficiency is important to minimize fuel consumption and unwanted excess to the environment. Stable and efficient combustion requires correct mixture of fuels and oxygen. Properties like heat values, air/fuel ratios, flame speed, flame temperatures, ignition temperatures, flash points and flammability limits.
