Stack Emission Monitoring 2015.

Descriptions

Emission measurement equipment. Environmental monitoring other than for construction. Air pollution monitoring or measurement services. LondonWaste Ltd (The Company) own and operate the EcoPark Energy centre located in Edmonton, London. The Energy Centre has five boilers burning approximately 500 000 t of both trade and 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 5 m³ 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 415oC. Material which remains after the incineration process is transferred to the residual conveyors for onward transfer for further treatment and recycling.The flue gas treatment plant consists of 4 streams each designed to treat up to 137 500 Nm³/h of flue gas. Each boiler may deliver up to 110 000 Nm³/hr of flue gas at a temperature of around 190oC.The superheated steam from the boilers is used to drive four single cylinder, 17 stage turbines to generate electrical power at 11 kV. This power is used for the house load with the surplus exported to the National Grid via two step-up 11/33 kV transformers. The power exported to the Grid averages 32 MWh.This specification is for the supply and installation of a brand new stack emission monitoring system that is MCERTS accredited for use in a waste incineration plant and able to comply with the Industrial Emissions Directive (IED). The procurement also includes testing, installation and commissioning of the system by the successful supplier. Provision of a comprehensive maintenance contract to ensure the system is maintained and working continuously is to be included.All communication must be directed via the Delta e-sourcing portal.
