Waste Heat Recovery Boiler VS Heat Recovery Steam Generator


A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).

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 generate superheated steam, hence the name Heat Recovery Steam Generator.

The water steam circuit of an HRSG consists of an economizer, an evaporator, and a super-heater placed in the flue gas duct. The evaporator section consists of a drum to which the coils are connected to create the circulation.
HRSG deals with Hot exhaust Gas of Gas Turbines which is used to heat Water. The exhaust gas is less particulate and can be vented through chimney.

Waste Heat Recovery Boiler is a system which recovers various kinds of waste heat generated from the production process of steel, non-ferrous metal, chemical, cement etc and those equipment of industrial furnaces, refuse incinerators, industrial waste incinerators, and convert such recovered heat into useful and effective thermal energy. Waste Heat Recovery Boiler is contributing to industrial society in terms of improvement of thermal efficiency, energy saving, environmental protection etc.

WHR(waste heat recovery) Boiler deals with highly particulate flue gas. The place where burnt hot ash at very high temperatures needs to be cooled down before its properly disposed.
ZBG can provide a variety of waste heat recovery boilers, including carbon rotary kiln waste heat boiler, float glass kiln waste heat boiler, coke waste heat boiler, chemical industry flue gas waste recovery boiler and so on. if you want to know more information about waste heat recovery boiler VS heat recovery steam generation, please contact [email protected] or call 86-371-86062323.
