Abstract: A fuel strainer for use in a turbine that filters debris out of fuel feed lines of the turbine to prevent clogging of flame nozzles in the turbine. The strainer comprises an elongated straining member with a plurality of apertures therethrough. The sum of the cross-sectional areas of the apertures is significantly greater than the cross-sectional area of the fuel feed line, and each individual aperture is smaller than all of the fuel holes in the flame nozzles.

Abstract: A turbine fuel valve packing assembly including two sets of packing rings in which at least one packing ring is a V-shaped packing ring, a compression member, lantern ring, and packing gland with a sealing ring is disclosed which effectively seals turbine fuel valves against leaking. Further disclosed is a valve packing replacement method utilizing a bifurcated valve shaft allowing part of the shaft to be removed, thereby providing enough space for the valve packing assembly to be removed from the fuel valve and replaced without disassembling the entire fuel valve.
