The heat recovery steam generator (HRSG) recovers heat from the gas turbine exhaust to generate steam at temperatures up to ∼650°C and pressures of 13–20 MPa. Although supercritical systems have been developed, heat recovery steam generation is most commonly applied under subcritical conditions.

This paper describes the technology behind waste heat recovery and the potential for ship-owners to lower fuel costs, cut emissions, and the effect on the EEDI of the ship. Introduction
Indeck is the only steam generating equipment supplier that has been providing green power for decades! Indeck has engineered, manufactured, and installed large capacity equipment ranging in size from small packaged units to large field erect boilers with capabilities of burning multiple and unique "green" fuels.
Heat Recovery Steam Generator (HRSG) Many highly efficient industrial plants with cogeneration or combined cycle systems use a gas-turbine (essentially a jet engine) to generate electricity then create steam from the waste heat using a heat recovery steam generator (HRSG). This section will explain how this process works and how an HRSG comes into action. Consider the previous example of a …
A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat Economizer: In case of process boilers, waste heat in the exhaust gas is passed along a A WHRB is different from a Heat Recovery Steam Generator (HRSG) in the sense that the heated medium does not change phase.
Modular HRSG A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). 1 HRSGs
Waste Heat Recovery Systems (WHRS) are revolutionary energy-saving power generation system that recover and reuse energy from the main engine's exhaust gas. WHRS optimize thermal efficiency by automatically adjusting the output according to on-board electricity demand.
Heat Recovery Steam Generator (HRSG) Heat Recovery Steam Generators are used to recover waste heat from the exhaust of gas turbines, boosting efficiency from a range of 35% to 40% in a simple cycle (also known as open cycle) mode to a range of 55% to 60% in a combined cycle mode.
