HRSG Boiler Explained: How Heat Recovery Steam Generators Work| Boiler Interview Question | Boiler PDF HRSG stands for Heat Recovery Steam Generator. It is a special type of boiler used mainly in combined-cycle power plants. Unlike a conventional boiler, an HRSG does not burn fuel directly to produce steam. Instead, it captures the hot exhaust gases coming from a gas turbine and uses that waste heat to generate steam. Main Components of an HRSG: Economizer – Preheats feedwater. Evaporator – Converts water into steam. Super heater – Raises steam temperature above saturation. Drum (in drum-type HRSGs) – Separates steam from water. Why HRSG Is Important Recovers waste heat that would otherwise be lost Increases power plant efficiency Reduces fuel consumption Are you preparing for a boiler operator job interview or trying to understand how commercial and industrial boiler systems work?
