How To Calculate Waste Heat Recovery Boiler Thermal

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 The exhaust heat loss is the heat loss caused by a part of …

WASTE HEAT RECOVERY BOILERS - Johnston Boiler

fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are greenhouse gas emissions and the load on the cooling system.
