Case Studies
Energy Centre at Ahlstrom
Ahlstrom Fiber Composites (Ahlstrom) manufacture non-woven textiles at its plant near Duns in the Scottish Borders. The plant received power via two parallel overhead lines that were historically problematic. The steam raising boilers were nearing the end of their useful life. The nearest gas supply pipework was a few miles away and there were no plans by the utility to supply the area with gas.
Scottish and Southern Energy, in its capacity as an Energy Services Provider, engaged Cadogans as engineering consultants.
Cadogans carried out a feasibility study for SSE and concluded that a 4MWe CHP and associated new steam boiler plant would best serve the needs of the host site. The site had a fairly consistent demand for both steam and electricity making it an ideal candidate for CHP. There was little or no demand for low grade heat and this together with other reasons made the case for a gas turbine to be the prime mover.
Specifications were written by Cadogans and tenders were received for the gas turbine packages and steam boilers. Cadogans commenced engineering design of the associated services taking into account the need for minimal disruption of site production.
In parallel SSE negotiated with the gas utility for the supply of a substantial gas main.
