Credfeld were involved with a UK Power Generation company to provide a new Burner Management and Combustion Control System, which included new Credfeld LT300 Igniters.
The system was designed to meet a safety level SIL 1 and IE61508 and to achieve this we utilized an Allen Bradley PLC Control Logix processor. The control of the burners was modified to enable the burner to fire in pilot only mode which in turn minimized the Gas usage during GT operation. By maintaining a continuous ignition source (Pilot Only Mode) within the boiler enabled immediate Ignition of the main Gas burners in the event of a Gas Turbine trip.
"We would like to take this opportunity to thank Credfeld on the supply, support and commitment you gave RWE in delivering this difficult contract. SCA have indicated to us that they are very happy with the final outcome and that the Gas savings exceeded the initial estimates. In addition we thank you for providing a well constructed programmed PLC. "RWE Npower
