Introduction to Condensate Recovery | TLV - A Ste

If 1 t/h of steam is supplied to equipment for a heating process, then the same amount of condensate (1 t/h) needs to be discharged from the equipment. Condensate recovery is a process to reuse the water and sensible heat contained in the discharged condensate. Recovering condensate instead of throwing it away can lead to significant savings of

Heat Recovery Boiler - an overview | ScienceDirect Topi

The saturated steam produced in the heat recovery boiler is superheated prior to entry into a steam turbine generator which makes electricity. Superheating occurs in a superheater. A superheater is another heat exchanger, which cools gas after catalyst bed 1 ( Chapter 9 ) and superheats that steam for power generation.

Heat Recovery Steam Generator - an overvi

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.

Heat Recovery Steam Generators (HRSG) | GE Power

Difference Between Heat Recovery Steam Generators (HR

Heat Recovery Steam Generator’s (HRSG’s) are waste heat boilers. The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant. In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to

  • Heat Loss · Saturated Steam · Steam Turbine · Preferences · Header · Steam The boilers use X-ID tubing for enhanced heat transfer through the helical ribs on the inside of the tubes. The Waste Heat Boiler package is a skid-mounted unit, forced circulation, fire tube, and heat recovery steam generator. The unit has automatic, modulating, exhaust gas bypass that is controlled by steam pressure. A boiler feedwater and
