Boiler efficiency and its calculation

Question

Accepted Answer

Boiler efficiency is the ratio of energy output to energy input. It can be calculated using various methods.

Boiler efficiency is important for reducing fuel consumption and emissions.
It can be calculated using the direct method, indirect method, or heat loss method.
Direct method involves measuring all the energy input and output parameters.
Indirect method involves measuring all the energy input parameters and calculating the energy output based on the heat balance equation.
Heat loss method involves measuring all the energy input parameters and subtracting the heat loss from the energy input.
Boiler efficiency can be improved by regular maintenance, proper insulation, and optimizing combustion.
Efficiency can also be affected by factors such as fuel quality, load variation, and ambient temperature.
