Geometric and Thermodynamic Optimization of a Heat Recovery Steam Generator: A Constructal Design

Heat recovery steam generator (HRSG) is a critically important subsystem of a combined cycle. The global objective of a HRSG is to heat the stream of water. The HRSG is composed of three major sections, including an economizer, an evaporator, and a superheater. In this study, a water tube HRSG is considered and its main design features are deduced from the minimization of the entropy generation by using the constructal theory. Entropy generation...
