RENTECH is the industry leader in HRSGs for gas turbines up to 40 MW. RENTECH offers 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 or “A” type configurations available
Convection type superheaters
Fresh air firing to provide uninterrupted steam production
