Difference Between Heat Recovery Steam Generators …

In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to generate superheated steam, hence the name Heat Recovery Steam Generator. The water steam circuit of an HRSG consists of an economizer, an evaporator, and a Super-heater placed in the flue gas duct.

Design methodology of heat recovery steam …

The flow of the working fluid (water or steam) in the pipes is horizontal and the flow of exhaust gasses is vertical, which means each heat exchanger in the HRSG can be considered to be a cross flow heat exchanger as shown in Figure 1. The fluid in the evaporator undergoes forced circulation by pump for both pressure levels.
