Our capacity and workscope in thermal design and construction spans BIB Cochran’s entire shell boiler output in the gas-fired Borderer, Wee Chieftain and Thermax Ranges, from a few hundred pounds per hour for a small dyehouse to over 15 tonne/hour for a factory making expanded polystyrene products. Earlier installations included various oil-fired boiler plants for Northern Foods factories at Uttoxeter and Middlewich, and improving the thermal design of coal-fired installations during the energy crisis of the 1970s under DTI-funded programmes.

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 thermal design effectiveness, maintenance and operating requirements, and capital cost. One of our most extensive schemes was installed at BXL Leicester, serving 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, and for whom we have undertaken wide-ranging thermal design and plant 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 designing and building special-purpose plant such as flue gas economisers, recuperators, feed tanks, hotwells etc. to meet specific site requirements and improved thermal design standards, whilst others entail the start-to-finish thermal design, mechanical layout and prototyping of proprietary process devices and equipment.

Current emphasis in reclaim and low energy schemes is on cascaded heat conversion systems, matching available energy formats with local loads at higher effectiveness levels than formerly targeted. Examples include adsorption chillers for supermarket and warehouse refrigeration, drawing off energy-from-waste boiler and power plant. We undertake thermal design and 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.
