Finning delivers CHP unit to Boston Scientific

Finning has supplied a combined heat and power (CHP) solution to the Boston Scientific manufacturing facility in Cork, Ireland, delivering energy-saving efficiencies of up to 23,328kWh of primary energy per day.

The site, which manufactures more than 5.6 million life-saving devices for the company’s cardiology, rhythm management and vascular group, endoscopy, and urology and pelvic health divisions, has invested in an 800kW gas fired CHP unit to help cut energy costs, improve Operational efficiencies and increase sustainability.

CHP system generates electricity on-site while alsocapturing the usable heat that is produced during this process. In contrast with conventional means of generating electricity, which are typically only 40 per cent fuel-efficient with all the potential heat energy simply going to waste, CHP technology can increase a site’s energy efficiency dramatically, with Boston Scientific now achieving a total efficiency rating of 87.7 per cent when compared with conventional electricity generation.

Featuring a containerised, highly efficient Catà‚® CG132-16à‚ natural gas-fired generator setà‚ with an electrical output of 800kWe at 400 volts, the system will also generate up to 406kWt from the engine’s water jacket circuit and 450kWt from the exhaust, providing low temperature hot water that can be used for the site’s utility building services and manufacturing processes.

Offering a payback period of less than three years, Niall Ahern, Facilities Engineer at Boston Scientific, explains: “We began the process of looking to improve our operational efficiencies more than two years ago, with CHP offering the best all-round investment for us in terms of cost, efficiency and sustainability.”

The 800kW unit is a fuel-efficient energy technology, capable of providing for 80-90 per cent of the facility’s electrical requirements at weekends and 60-70 per cent of electrical requirements during the week, depending on demands. It helps power a range of utility equipment, humidifiers, air handling units and compressed air systems, as well as Controlled Environment equipment and lighting.

“The integration of the CHP plant was one of the largest, most complex projects to be delivered at our site in Cork last year, and we expect it will continue to provide a good return on investment,” added Ahern.heà‚
