RENTECH is the industry leader for HRSGs for gas turbines up to 40 MW. We offer designs based on application and operating conditions.


Cross Flow Two-Drum HRSG

  • Complete shop assembly to minimize installation cost
  • Saturated or superheated steam application
  • Remote steam drums for higher steam capacities or shipping restrictions
  • Unfired or supplementary fired applications
  • Multiple gas passes for smaller gas turbines


Waterwall HRSG

Our waterwall HRSG shares many design features with our industry-leading direct fired packaged boilers. We design RENTECH waterwall HRSGs for applications that require high levels of supplemental firing.

  • Single-pass gas flow to minimize gas side pressure drop
  • Supplemental firing temperatures to 3,000°F
  • O type boiler or A type boiler
  • Convection type superheaters
  • Fresh air firing to provide uninterrupted steam production
