Fuel splitter valve assembly for gas turbine
TL;DR: In this article, a fuel delivery system incorporating a splitter valve assembly is described, including a first valve (40) having a selectively positionable spool (42) disposed therein for controllably metering fuel flow therethrough for delivery to a first combustion chamber and a second valve (50) operative to pass a second portion of the fuel flow to a second combustion chamber while maintaining at least a desired minimum pressure upstream of the first valve.

Volumetric gas mixing system
Beck W,Crawford J +1 more
TL;DR: In this paper, a system for mixing gases volumetrically by comparing relative flows between the constituent gases and the combined total gas flow is presented, where a signal is supplied to a regulator valve in line with the constituent gas flow conduit to vary the amount of flow therein until the correct proportion is established.
Patent
Combustion control valve means and system
TL;DR: In this paper, an air damper or valve is located in an air inlet pipe to a blower and a gas supply pipe is also connected to the inlet manifold adjacent the blower, and a modulating-type pressure regulating valve controls the rate of gas flow and adjusts the modulating valve to maintain an outlet pressure that provides a fuel/air ratio substantially constant.
Patent
Burner control system
Gregory Young,David Kucera,Donald J. Kasprzyk,Willem Super,Jos Praat,Roelof Thiewes,Hans van der Mei,Brian Zabel,Mitchell John D +8 more
TL;DR: In this paper, the authors proposed a burner control system for improving burner performance and efficiency, where a sensor connected across the air and fuel channels is used to determine fuel and air channel or manifold parameters, and a signal from the sensor may control the parameters which in turn affect the amounts of fuel or air to the burner via a controller.
Patent
Gas valve with communication link
TL;DR: In this article, the authors describe a valve assembly with an inlet port, an outlet port, and a fluid path extending between the inlet and outlet ports, one or more valve actuators for selectively moving respective valves, and sensors for sensing the parameters within the fluid path and a controller secured relative to the valve body and in communication with the sensors.

Patent
Pilot control for primary and secondary fuels
TL;DR: In this paper, a method of and apparatus for proportioning and controlling primary and secondary fuels, as well as combustion supporting air, used in a furnace installation, employing pilot fluid as a controlling medium.
Patent
Gas proportioning system
TL;DR: In this article, an improved control arrangement for a gas-air mixing unit was proposed, which results in greater safety of operation, anc also in improved performance with regard to production of a uniform air-gas ratio.
