Rolls-Royce Avon 1533-75L fuel system retrofit for Kristiinankaupunki reserve power plant

Fingrid Oyj

Fingrid is operating 16 Rolls Royce Avon 1533-75L diesel #2 fuelled gas generators in twin pack configuration for grid stability reserve duty. In order to extend the service life and improve the reliability and availability of these installations the high pressure fuel delivery systems of these gas generators are to be modified by replacing them with heavy duty industrial equipment. This purchase will cover four (4) of these gas generators (two twin pack units). The twelve (12) remaining units shall be included as an option.
Preliminary proposed scope of delivery, to be finalized during the negotiated process:
— design of high pressure fuel system modification,
— removal of original fuel system components to be replaced,
— eventual modification and blanking of engines systems and piping,
— manufacturing and delivery of fuel pumps, modulating valves, control devices and valves and other equipment and piping to complete a fully functional system,
— installation and testing of delivered units and systems,
— training and introduction of operators for use of new hp fuel system,
— cold and hot testing of modified installation including adjustment of safe fuel flow for all necessary transient and static conditions including start and shut down and trip/emergency situations,
— operation and maintenance documentation of new hp fuel system.
The supplier is also encouraged to propose other recommendable Avon system retrofits in this conjunction as an option. Examples of these are Variable Inlet Guide Vane (VIGV) and start bleed valves actuation and position indication and exhaust gas thermocouple and harness system that all are found to be maintenance intensive objects.
