Difference Between Heat Recovery Steam Generators (HRSG

Heat Recovery Steam Generators - HRSG,s are an important part of the Combined Cycle Plant. How is it different from the combustion boilers? Some of the main differences are given in this article. Heat Recovery Steam Generator's (HRSG's) are waste heat boilers. The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.
