Boiler Plant Condensing Heat Recovery System
A Condenser Heat Recovery System was installed, reducing its boiler exhaust temperature in the flue from 230°C to 25°C. This has resulted in improved boiler efficiency of 11.39%.
The return water on the site heat loop has been preheated from 78°C to 82°C prior to return to the 4Mw medium temperature hot water boilers. This massive reduction in energy has resulted in extrapolated savings of approximately £30,000 per year and a reduced carbon footprint of 151 tonnes of carbon.
The Condenser Heat Recovery System recovers waste heat energy from the flue gas exhaust of two water boilers. The recovered “free” energy has been utilised for return water pre-heating and used for ward heating.
The system was designed using technology developed during the last oil crisis, which has been refined and improved resulting in the state-of-the-art technology installed at this site. The project was a total turnkey installation, installed and commissioned prior to project handover.
