FIRE WATER PUMP REPLACEMENT

2026-11-03

A) Introduction LondonEnergy Ltd (The Company) own and operate the EcoPark Energy Centre located in Edmonton, London. The Energy Centre has five boilers burning approximately 500,000 tonnes of domestic refuse per year in a continuous 24-hour operation, 7 days per week. The waste is delivered by road via the weighbridges/gate house by various types of transport. The waste is tipped and held in storage bunkers. Waste is fed by three 5m3 grabbing cranes from the storage bunkers to the feed chutes of each boiler. Each of the water tube boilers is operated to achieve an evaporation rate of 40 tonnes per hour, at a steam pressure of 41.5 Bar and temperature of 415 OC. Material which remains after the incineration process is transferred to the residual conveyors for onward transfer for further treatment and recycling. Within the EcoPark, there is a firewater ring main system consisting of: 1) 2 x Firewater Pumps 2) 1 x Sprinkler Header with level control (float switch start) 3) 1 x Fire Water Ring Main (with pressure-controlled start capability) 4) 40 x Isolation Valves 5) 18 x Fire Hose Points 6) 18 x Fire Hose Connections 7) 20 x Fire Hydrants 8) 1 x Crossover Pipeline (for pressure compensation - to be decommissioned and replaced with the jockey pump) The Eco Park Firewater Pump Project aims to install two new diesel firewater pumps and integrate them with the London Energy DCS system. This will enhance the control, monitoring, and visibility of the fire protection system compared to the currently installed setup. Additionally, a new jockey pump will replace the existing crossover system to maintain pressure in the Firewater Ring Main. In addition to the installation of two new firewater pumps and a jockey pump, this project requires enhanced visual, audible, and control capabilities. All components and alarms must be integrated with the SCADA system, ensuring seamless monitoring and control.
