RKP LIQUID FUEL METERING SYSTEM Energy Saving, Compact ENERGY EFFICIENCY FOR GAS TURBINE OPERATORS With today’s escalating energy costs, the manufacturers of Dual Fuel Gas Turbines are constantly looking for ways to improve efficiency, and meet ever more stringent emissions requirements. Key to these needs is the Liquid Fuel Metering function, which directly controls the supply of liquid fuel to the turbine burners (e.g. comparable to diesel). Moog has been working on fuel metering technology to improve performance for over 20 years. • Improved reliability due to integrated construction Moog has developed a new fuel efficient fuel metering system using tandem variable displacement RKP pumps with up-rated compensator and revised spring configuration to improve frequency response. Liquid fuel Moog Direct Drive Valves (DDVs) are mounted to the pump to independently control flow to the main burner and the pilot burner and to ensure fuel is supplied on demand rather than by spilling excess flow (as in the traditional system). Consequently the new Moog system typically uses a 22 kW AC motor whereas the traditional system often requires a 30 kW motor, already demonstrating reduced in service running costs (energy saving). This technology has already been applied to turbines of power levels of up to 15 MW corresponding to fuel flow rates ofup to 100lpm (26.4 gpm) at 100 bar (1450 psi). Typical fuel types that have been accommodated include diesel and diesel derivatives. The system is ATEX certified for use in Group 2, Category 3 hazardous areas.
