A method for calculating the thermal efficiency of a boiler.
Boiler thermal efficiency refers to the percentage of fuel heat into the boiler that is effectively utilized.
The efficiency of modern power station boiler can reach more than 90%.
Industrial boilers can be up to 75% efficient.
The heat of fuel sent into the boiler is lost in various forms except for the part that is effectively used.
Incomplete combustion heat loss of gases caused by unburned carbon monoxide, hydrogen and methane in exhaust smoke;
The solid incomplete combustion heat loss and heat dissipation loss caused by the unburned carbon contained in fly ash, slag and grate leaking coal etc.
