The power station at Pembroke in South Wales is, at 2,160MW, the largest combined cycle gas turbine (CCGT) power plant in the UK. It was recently built for RWE npower. Following a number of previous contracts with both RWE and the main contractor, Hager + Elsässer was chosen to design and supply the process water system to feed the gas turbines.
The design process itself incorporated a number of features preferred by the client in the light of their experience of operating H+E’s water treatment plants at other power stations and also some features preferred by H+E as a result of its own prior experience. In both cases, this was in keeping with the business philosophy of “Continuous Improvement”.
Since the supply of pure water is fundamentally important to the production of the high quality steam required to drive the gas turbines efficiently, the design and ability of the water deionization plant to perform efficiently in the long term, with minimal down-time is also of great importance to the business.
