East Road Energy Centre

This project entails the provision of Premier Inn Hotel, 700 No. Student Dwellings and 10 Storey Office Block, set over basement and ground floor levels at 10 East Road, 10 East Road, Islington, London, N1 6AD

East Road Energy Centre

The heat is produced in the Energy Centre which is located in the basement and is distributed in the Energy Centre to a plate heat exchanger which serve each block individually. The heat exchangers are sized to provide 600kW to the Hotel, 1,150kW to the Student Accommodation and 460kW to the Office Block. CES Energy are not responsible for the plant items and installation on the secondary side of the heat exchangers.

The bespoke energy centre is situated in the North Block Basement containing 1 no. Combined Heat & Power (CHP) generating unit, 2 No. fully modulating condensing gas boiler comprising of 2no. modules each, 2 no. primary pumps, 5 no. shunt pumps, primary pressurisation units c/w expansion vessel and a secondary pressurisation unit serving the CHP dump cooling circuit. Each piece of plant was finely engineered to produce significantly greater efficiencies and enhanced pollution control. The flue which comprises of insulated stainless steel twin walled stacks, runs 65m vertically terminating above lift over-run.

The CHP is controlled automatically and is set as a lead boiler to lean towards a greener environment.

Operation of the gas boiler is regulated by its controller which is located on the left hand side of the MCC panel. Unison control is incorporated which steps each boiler module on in turn at its lowest rate, and then modulates all boiler modules simultaneously to higher rates to match the system load. This method of sequencing offers higher operating efficiencies, taking advantage of the higher part load efficiencies available at low firing rates. Temperature output is controlled by the same controller based on weather compensation.

Pumps serving the Energy Centre are controlled by self contained variable speed drives and are designed and set to maintain constant pressure. Automatic change over of the pump heads is controlled by the integrated speed drives and is set to change duty every 24 hours.

The degasser and pressurising unit constantly monitors the system pressure and is set to maintain operating pressure of 3.0bar.

Boiler room piping is made of medium grade seamless steel pipes. Piping up to DN50 has threaded connections and above DN50 welded and flanged connections.
