Isle of Man Hospital Steam Boiler Economiser

When Noble’s Hospital on the Isle of Man was looking to reduce operating costs ThermTech designed, manufactured, and retrofitted three bespoke boiler economisers to help them do this.

Project Details

Location: Isle of Man
Industry: NHS hospital
Construction: Carbon steel, BE SEN 12952, PE(S)R CAT IV
Key Points: 5% uplift in Boiler efficiency, ROI period 3 years

Further Information

The hospital had two 6,000 kg/hr and one 4,000 kg/hr natural gas fired steam boilers running at 10 bar g each. Each boiler economiser cools the boiler flue gases from 240 to 160 °C, thereby preheating boiler feed water from 110 to 135°C, resulting in a ~5% uplift in boiler efficiency. The consequent savings in fuel mean the project will pay for itself in just 3 years from the date of commission.
