Heat Recovery Boiler - an overview | ScienceDirect Topics

By using a HRSG for recovering the waste heat from the exhaust of a 60-MW gas turbine, an additional power of 35.14 MW can be generated, thus increasing the overall plant efficiency from 33% to 52%. The heat transfer coefficients of gas are weak; therefore, the designed HRSG has a large area to produce steam at high pressure and temperature.

3.6 Heat recovery boiler. The heat recovery boiler serves to cool the SO2 -bearing product gas and produce steam for electricity generation. Cooling occurs by feeding low-temperature boiler feed water around the fire tubes ( Fig. 3.4 ). The boiler feed water is condensed steam after electricity generation that has been conditioned in a deaerator.

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

HEAT RECOVERY BOILERS

HEAT RECOVERY BOILERS. Boilers of this type generate steam by extracting heat from hot fluid, generally a gas, which is produced as a by-product of a chemical reaction and has no intrinsic value as a chemical, or which is in the form of exhaust from a gas-turbine or internal combustion engine. Heat recovery boilers are also often found in
