College set to cut emissions

Atlantic Boilers has installed new boiler plant to heat a workshop and laboratory at the town centre campus of Stockport College.

The installation consists of two R22-500 dual fuel B100 bio-fuel/ natural gas lead condensing boilers, each rated at 530kW, and one NA-R 1160kW natural gas lag high efficiency boiler. The in-house control system ensures that the two R Series boilers take up most of the heating load.

The B100 bio-fuel is kept in two underground tanks at 5°C, then piped to a pre-heat tank within each R Series boiler, from which it passes to the burner. The B100 bio-fuel oil is said to burn with the same maximum condensing efficiency as fuel oil or natural gas, bringing savings in carbon emissions. In addition, the company says the space requirement is minimal and less than half the cost of bio-mass systems.
