SteamGen™ 6

SteamGen™ 6 is a HRSG variation of SteamGen™ 4 which offers the same unique benefits, but has the possibility of having a combined HRSG and auxilliary bolier added.

No internal insulation, water cooled combustion chamber Purification of steam to highest standards

SteamGen™ 6 is a HRSG variation of our SteamGen™ 4, which takes the best design a step further. In general the basic design offers the same unique benefits as our SteamGen™ 4, but the possibility of having a combined HRSG and auxiliary boiler is also a very import feature of the SteamGen™ 6.

Many industrial companies world-wide would benefit from this type of solution. For applications where there is a need for a limited power production, but with a large demand for steam, the SteamGen™ 6 is the optimal solution. With an ability to increase the steam production more than five times compared to an unfired HRSG, this design offers a performance, which is impossible for other types of HRSGs.

In the gas turbine size range 5 - 50 MWe, the SteamGen™ 6 has the ability for connecting an engine or gas turbine, thereby allowing it to have power producing capability. If steam is a lifeline on your plant, the SteamGen™ 6 is prepared for “flying change over”. If required the HRSG can be designed to automatically switch from GT to fresh air operation. This situation will in case of a GT trip secure your process plant steam and continued operation.

The SteamGen™ 6 boiler is designed according to internationally recognized boiler codes such as PED/EN.
