Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

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

Thermal Design and Optimization of Heat Recovery Steam

In a CCPP, the exhaust gas from the gas turbine is used in a heat recovery steam generator (HRSG) to produce steam. Then, the produced steam is used in steam turbines for electricity production. The gas turbine and the steam turbine produce approximately 65% and 35% respectively of the total produced power in a CCPP.

What is a Waste Heat Boiler? (with picture)

May 04, 2020 · A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.
