A Survey of Alternate Methods for Cooling Condenser

----- 3.7.4 Size Estimation For a power plant, the heat rejected is known as a function of condensing temperature. Hence, the equations above are used to determine the condenser design parameters (e. g., A and G) so that the condenser will supply the proper condensing temperature and reject the required amount of heat.

Design methodology of heat recovery steam

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.
