Heat Recovery System Generators (HRSG)

A heat recovery steam generator or 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).


Superior Boiler Works, Inc. offers waste heat recovery boilers in three basic designs to provide the greatest flexibility of any manufacturer in selecting a unit that is designed to meet the specific requirements of each application. Boiler designs are customized for specific job conditions to provide optimum performance and maximum energy savings.


Customized design engineered for your specific solution.

Pressures from 15-300 psi steam and 30-160 psi hot water

Available with dual chamber design or supplemental firing

Temperatures to 2,400° F

Roller-bearing supported single-hinged rear door for total fireside access (except wetback)

All Waste Heat Recovery Boilers are made with 12 gauge tubes, 3/4″ tube sheets with 3/4″ ligament spacing and furnaces thicker than ASME code requirements. All section I furnaces above 24″ diameter are corrugated to help reduce the stresses associated with expansion and contraction.

Superior Boilers offer thicker tubesheets, thicker tubes, large corrugated furnaces, and the ability to factory mount, wire and test UL or CSA listed burners from all burner manufacturers for dual chamber applications. Full front end and fireside access is standard on all Superior boilers. Our design eliminates the necessity of disconnecting fuel lines when inspection or maintenance functions are required.
