SteamGen™ 8 Projects

In projects where power production is the primary requirement SteamGen™ 8 offers the best and most readily available HRSG technology on the market.

Siemens - Bulgaria

Space is a limitation in many indoor Combined Heat and Power Plants. This was also the case in Plovdiv. The smart solution var to place the HRSG on top of the gas turbine. As the end user EVN,the contractor Siemens Sweden and Aalborg Engineering could accept the arrangement this became the logic for this project. The SteamGen™ 8 was selected and with its water cooled combustion chamber the capacity was reached without any limits of the design.

All equipment is purchased by Aalborg Engineering and the erection work is carried out by a subcontracted Turkish company.
