      Options for Improving the Efficiency of Heat Recovery

      The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a

      Difference Between Heat Recovery Steam Generators (HRSG

      Unlike the power plant boilers, there are no air or gas handling fans. The flow of gases is due to the exhaust gas pressure from the Gas turbine. Pressure drops in the gas path of a HRSG is at a minimum to avoid higher exhaust gas pressure, which will affect the performance of the GT. This also eliminates the need of air preheaters.
