Once Through Heat Recovery Steam Generators (OTHRSG)

In 2006, EN-FAB, Inc. was awarded a contract to design, manufacture and supply six (6) Once Through Heat Recovery Steam Generators (OTHRSG) for Solar Titan 130 Gas Turbine Generators (GTG). Each of the six OTHRSG units has a capacity of 100 MMBTU/Hr.

 

 

Each system consists of:

 

  • Bypass System with diverter damper, expansion joints and stack

 

  • Transition duct sections and main stack

 

  • Convective Section with coil assembly for steam generation

 

  • Duct Burner System with three horizontal elements. Each system complete with main and pilot gas headers, redundant skid-mounted scanner cooling air blowers and an integral exhaust gas flow distribution grid

 

  • Fuel gas skid

 

  • Burner management system

 

  • Feed water high pressure pump

 

  • Feed water heat exchanger

 

  • Steam separator, designed for 99.95% separation efficiency

 

  • Air cooled heat exchanger

 

  • All interconnect pipes and valves.

 

  • Modified ISO climate control container for housing of the control panel and MCC/VFD panel. The control system automatically adjusts the fuel – water ratio parameter to keep the steam quality at 80% at all operating levels.

 

  • EN-FAB’s HRSG systems are custom designed to meet your desired operating performance requirements. Our well qualified and experienced personnel can also supervise field installation, start-up and commissioning of the units.
