Embodiment Construction

[0028] Referring now to the drawings, wherein like numerals refer to like elements in the several drawings, figure 1 A schematic diagram of a gas turbine engine 10 that may be described herein is shown. Gas turbine engine 10 may include a compressor 15 . Compressor 15 compresses incoming gas stream 20 . Compressor 15 delivers compressed airflow 20 onto combustor 25 . Combustor 25 mixes compressed gas stream 20 with pressurized fuel stream 30 and ignites the mixture to generate combustion gases 35 . Although only a single combustor 25 is shown, the gas turbine engine 10 may include any number of combustors 25 . Combustion gas flow 35 is then delivered to turbine 40 . Combustion gas flow 35 drives turbine 40 to produce mechanical work. The mechanical work produced in the turbine 40 drives the compressor 15 and an external load 50 such as a generator and the like via a shaft 45 .

[0029] Gas turbine engine 10 may operate on natural gas, liquid fuels, various types of synga...

Abstract

A fuel metering valve system for use with a flow of fuel in a gas turbine engine may include a number of orifice plate lines, a number of differently sized orifice plates, and a number of orifice plate line valves. One of the orifice plate line valves opens and closes one of the orifice plates on the orifice plate lines.

Description

technical field [0001] The present invention and the corresponding patents generally relate to gas turbine engines, and more specifically to a fuel metering valve system with a plurality of orifice plates of different sizes. The orifice plate operates on and off as required. Background technique [0002] In general, fuel flow to a combustor of a gas turbine engine can be carefully monitored and controlled so that the gas turbine engine produces a required output while still meeting emissions regulations. Changes in output demand, as well as changes in various other types of operating parameters, may result in changes in fuel demand. Fuel flow controllers therefore need to provide the ability to very precisely adjust fuel flow to meet such demands. Specifically, fuel flow controllers must provide reliable operation over a wide range of loads as well as control of emissions, ambient conditions, fuel composition, and other types of operating parameters. [0003] Generally, g...
