Boiler Economiser - Industrial Steam Boiler Manufacturer

The Heat Recovery Steam Generator. Economizers are one of the main components of a heat recovery steam generator (HRSG). An HRSG is a highly efficient heat exchange system that recovers heat from the hot exhaust gas and produces steam. Often, HSRGs reclaim heat from gas turbines, which creates steam to drive steam turbines.
