Turbine Generator Overhaul and Maintenance 2015.
Descriptions
Steam-turbine generator and related apparatus. Turbine generator sets. Turbine generator control apparatus. Turbines and motors. Steam turbines. LondonWaste Ltd own and operate the EcoPark Energy centre located in Edmonton, London. The Energy Centre has five boilers burning approximately 500 000 t 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 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 t per hour, at a steam pressure of 41,5 Bar and temperature of 415°C. 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/h of flue gas at a temperature of around 190°C.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.A planned maintenance shut-down of approximately 5 weeks duration is undertaken on one of the four turbines annually, this usually coincides with the boiler outages. This specification is for the supply of turbine and generator overhaul and maintenance services to the Energy Centre during shut-down periods. The principal objective of this specification is to ensure that the Company has competent resources available during planned and unplanned turbine and generator outages to provide overhaul and maintenance services.It is intended that the contract for the works defined in this specification will be for an initial period of 4 years with an option to extend by a further 12 months subject to agreement by both parties.ALL communication must be directed via the Delta e-sourcing portal. You will need to register as a supplier on Delta which is free and takes less than 10 minutes.Important — The PQQ Access Code is B59XS537B9. You will be required to complete the PQQ and submit it together with all relevant attachments before the stated deadline. Failure to comply will result in your organisation being excluded from the process. A copy of the Invitation to Tender is provided in excel format for viewing only at this stage.
