SteamGen™ 6 Projects
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.
Babcock-Hitachi - Hungary
In June 2005 Aalborg Engineering signed a contract with Babcock-Hitachi Europe to supply a HRSG with supplementary firing for the NYKCE power plant in Nyíregyháza, Hungary.
The SteamGen™ 6 in a design with two steam pressure levels and hot water generation has been selected for this project. Aside from power production the plant will supply process steam for industry consumers and district heating for the city Nyíregyháza.
The contract covers design, procurement, production, erection supervision and commissioning supervision of a dual-pressure HRSG with supplementary firing system.
