Combustion Efficiency Testing

Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiencyCombustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat.

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%.

The resulting value is the boiler’s fuel-to-steam efficiency. The heat balance method accounts for stack losses and radiation and convection losses. Stack Losses: Stack temperature is a measure of the heat carried away by dry flue gases and the moisture loss. It is a good indicator of boiler efficiency.
