Waste Heat Recovery / HRSG

Waste Heat Recovery systems utilise existing energy sources in order to efficiently generate thermal heat, process heat or electricity.

These systems reduce energy costs, provide carbon credits for emission trading systems and help the environment by reducing emissions.

HRSG – Heat Recovery Steam Generators

There are a form of waste heat recovery often applied to the exchange of gas turbines to recover energy as high pressure steam. Frequently the GT exhaust is augmented with additional heat input using supplementary firing using in-duct burners between GT and HRSG. HRSGs are usually used to provide steam to steam turbines for power generation. This is known as Close Cycle Power Generation (CCPG).
