Efficient Process Heating - Energy

In a steam boiler the heat from the flue gas is transferred to the water, which then turns into steam. Downstream of the boiler the flue gases are still high in temperature and are typically 50ºC or more above the steam temperature. Flue gas heat exchangers downstream the boiler can recover this waste heat and improve the boiler fuel efficiency.

PEOPLE Boiler Efficiency - energy

The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss
