Fire detection and prevention equipment supplier, Argus Fire, has secured a £1 million contact from Mercia Waste Management to design and build the fire prevention systems for the new EnviRecover waste to energy plant near Stourport.

The EnviRecover waste to energy plant has been financed by Worcestershire County Council and Herefordshire District Council, with Swiss waste to technology provider Hitachi Zosen Inova (HZI) acting as the main Engineering, Procurement and Construction (EPC) contractor.

Argus Fire, which is based in Stourbridge itself, said the contract will be carried out by its new Special Risks Department, which specialises in protecting industrial premises where the highly combustible materials used or processes employed carry a more devastating fire risk than normal.

The company added that the new department has already started work on site, installing mechanical water-based fire protection systems, fire detection and alarm systems and gas suppression systems, with the project scheduled for completion in May 2016.

The water-based fire protection systems at the EnviRecover facility will include a 1000 cubic metre tank and a pump house with pumping systems approved to the NFPA20 (National Fire Protection Association) standard that are capable of delivering 10,000 litres of water a minute to meet a worst case fire scenario.    

Argus Fire explained that it will also fit sprinkler systems to the waste bunker roof, tipping hall roof, shredder motor room, ammonia storage area and emergency diesel generator, as well as remote controlled fire water monitors to the waste bunker and below-ground fire hydrant mains.

In addition a deluge water spray system will be installed to cover the control room windows, waste hopper openings, steam turbine bearings and steam turbine lube oil skis, while foam-enhanced sprinkler systems will serve the boiler burners. 

The company will also provide an addressable fire detection and alarm system connected to five fully networked open protocol fire alarm panels and a disabled refuge panel. 

The devices, which identify the area of the site immediately when triggered, include smoke and heat detectors, break-glass units and sounder beacons, a very early smoke detector VESDA air sampling system, triple IR flame detectors and thermal imaging cameras.

These will be fitted across the admin building, weighbridge, turbine hall, air cooled condenser area, pipe bridge, tipping hall, waste bunker, boiler hall and flue gas treatment area.   

Argus Fire added that it will also provide six inert gas fire suppression systems that use the clean agent IG541 (50% Nitrogen, 40% Argon and 10% Carbon Dioxide) for the plant’s distribution control system and motor control centre for the plant crane, as well as for the main equipment room and server rooms, uninterruptible power supply (UPS) room, low voltage (LV) switch room and turbine control room.

The company is also providing Mercia Waste Management with 3D design information to support its installation coordination process. It said that this will result in the facility’s fire prevention systems interfacing seamlessly with other systems including door access controls, entry and exit barriers, lifts, roller shutters doors and its building management system.
