Rentech - Water-Cooled Furnace HRSG
Rentech’s water cooled HRSGs leverage our extensive experience in fired water tube package boilers and integrates that know-how into an HRSG that can be fired up to 3,000 degrees F (1648 degrees Celsius). These high firing temperatures allow for very high steam capacities from relatively small industrial or aeroderivative gas fired turbines. Typical applications include turbine sizes from 2 to 25 MWe. Steam capacities from 10,000 to +400,000 lb/hr (4,500 to 180,000+ kg/hr). Saturated or superheated steam. Pressures from 200 to 1,500+ PSI (14 bar to 105+ bar).
If a customer’s required steam capacity is higher than what can be produced from the turbine exhaust gas (TEG) alone, the Rentech water cooled HRSG can be designed with supplemental firing from a duct burner. Rentech duct burners can fire a wide range of gaseous and liquid fuels. Some typical fuels fired in Rentech duct burners include:
- Natural Gas
- Hydrogen
- Low-Sulfur Diesel
- Bio-Diesel
- Landfill Gas
- Refinery Off Gasses
Rentech’s engineers can design a system that will allow the duct burner to be fired and the system to produce steam, even when the turbine is offline. This operational mode is known as fresh air firing.
Rentech’s water cooled furnace design utilizes our membrane wall construction (link to membrane wall design and fabrication details). This proven design concept can be applied to both saturated and superheated steam applications. All superheater designs are convective type allowing for easier and more reliable operation of your HRSG system.
