Waste incinerators. Parts of furnace burners, furnaces or ovens. Thermal insulating material. Lining services. Steam-generating boilers. Refuse incineration services. Refractory works and maintenance - 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 weigh-bridges/gate house by various types of transport. The waste is tipped and held in storage bunkers. Waste is fed by 3 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 t/h, 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.
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 oC.
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 currently of approximately 24 days duration is undertaken on each boiler annually. The outage scope of works typically includes; annual statutory inspection; boiler tube thickness survey; replacement of boiler tubes; replacement of plate work and casings; refractory repairs; cleaning of the fireside spaces; overhaul of electrostatic precipitators; overhaul of roller grates, renewal of steel plate work as necessary.
This specification is for the supply of Refractory Works and Maintenance to the Energy Centre during normal operations and shut-down periods. The principal objective of this specification is to ensure that the Company has competent resources available during planned and unplanned outages to provide refractory services.
Potential suppliers will be required to demonstrate their capability to fulfil these requirements based upon their previous experience as part of their response to this Pre-Qualification Questionnaire. The duration of the contract is for a period of four years with an option to extend by a further 12 months, subject to agreement by both parties. ALL communication from providers during the procurement process must be directed via the Delta e-sourcing procurement portal. You will need to register as a supplier on Delta.
IMPORTANT -The PQQ Access Code is E6HNF75W8N. 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. Only those suppliers who are shortlisted will be invited to participate in the tender process. Thank you for your co-operation.
