Dove Thermal’s capacity and workscope in boilerhouse design & construction almost spans BIB Cochran’s entire shell boiler output in the gas-fired Borderer, Wee Chieftain & Thermax Ranges, from a few hundred pounds per hour for a small Leicester dyeworks to over 15 tonne/hour for Fibracan’s Skelmersdale factory making expanded polystyrene products.
Earlier installations included various oil-fired boiler plants for Northern Foods factories at Uttoxeter and Middlewich, and upgrading energy efficiency of coal-fired installations during the energy crisis of the 1970s.
We also design and fit-out central factory services blocks providing gas, compressed air, chilled process water and tower water supplies, together with effluent processing & water treatment plant. Proposed schemes are reviewed against benchmarks of energy efficiency, maintenance and operational requirements, and capital cost. Our most extensive scheme was for BXL Plastics at Leicester, undertaking a wide variety of thermoplastic manufacturing processes.
Changes in manufacturing economy means that there are now fewer large U.K. manufacturing sites. Companies like Tate & Lyle, Plessey, Alcan and English Sewing all supported considerable site infrastructures, for which we have undertaken detailed energy efficiency surveys and restructuring programmes. These mainly concerned steam-raising and distribution, also taking-in site cooling water and compressed air services, and site effluent systems. It was a special privilege to work with Silvertown Refinery, whose co-founder, Sir Oliver Lyle (“The Great Sir O.”), wrote “The Efficient Use of Steam”
and an equally seminal textbook on Sugar Technology.
Some projects necessitate our designing & building special-purpose equipment such as thermal economisers, recuperators, feed tanks, hotwells etc. to meet specific site requirements and improve energy efficiency, whilst others call for the production of manufacturing drawings under contract to third party builders of process equipment.
Current emphasis is on cascaded heat conversion systems, matching available energy formats with locally-created opportunities. Examples include adsorption chillers for supermarket and warehouse refrigeration, drawing off energy-from-waste boiler and power plant. We undertake energy efficiency advisory services similar to those previously available under DTI schemes and provide full environmental energy engineering survey programmes for any U.K. site.
