Liquid Fuel Metering for Gas Turbines

DLE Liquid Fuel Metering
Woodward is leading the way in controls and fuel metering systems for the next generation of Dry Low Emission Engines - Dual Fuel DLE. The first of these engines to go to market is the LM6000 PD engine. Woodward is supplying the controls and fuel system for the first engine to go to the field.

In the Liquid DLE Fuel system a single positive displacement pump is used to provide fuel to the system. The Bypass Valve (BPV) is used to provide the normal system bypass and also serves to provide closed loop control of the system pressure to the three throttling valves. Each of the three throttling valves meter fuel independently to the engine manifolds. Fuel flow accuracy of better than 2.5% of point mass flow is achieved by the fuel metering valves without expensive transducers or individual valve characterizations.

Liquid Shutoff Valve
The Liquid Shutoff Valve is a three-way valve designed to rapidly shut off all liquid fuel flow and prevent leakage to the turbine. In the de-energized state, the valve diverts inlet flow to bypass ports, preventing pressure damage to positive displacement fluid systems. Learn more from Liquid Shutoff Valve product spec 40135.

Liquid Shutoff Valve 25
The Liquid Shutoff Valve 25 is a three-way valve designed to rapidly shut off all liquid fuel flow and prevent leakage to the turbine. In the de-energized state, the valve diverts inlet flow to bypass ports, preventing pressure damage to positive displacement fluid systems. Normal installation of the 21.5 lb (9.8 kg) valve is in the fuel line between the fuel regulating valve and the turbine. The valve diverts flows from the discharge to bypass ports any time the operating electrical signal is lost. Learn more from Liquid Shutoff Valve 25 product spec 40169.

1907/EM35
The 1907 large liquid fuel valve accurately meters liquid fuel to a gas turbine during acceleration, steady-state operation, and deceleration. The valve may be used for almost any liquid-fueled industrial gas turbine application within its range of fuel flow (150 to 25 000 pph).

LQ Series
Woodward's LQ series of liquid fuel metering valves are designed for use on industrial and aero-derivative gas turbine engines in the 1,000 kW to 42,000 kW output power range.
