Difference Between Heat Recovery Steam Generators …

The exhaust gas temperature from a Gas Turbine is about 580 °C. Higher exhaust temperatures will reduce the efficiency of the gas turbine. In a conventional boiler where fuel burning takes place, the temperature head available for heat transfer is in the range of 1300 °C. The pinch point is the difference between the gas temperature

Pinch Point Temperature Difference - an overview

The value of the pinch-point temperature difference is a compromise between having a small cheap boiler (high δ) and having a good steam cycle efficiency (small δ). If the steam is superheated before leaving the steam generator there is a second pinch point at the exit.

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
