Product Description
Overview
The LQ6 liquid fuel metering system from Woodward is an integrated fuel control solution designed for industrial gas turbines operating on liquid fuels. This compact assembly combines a precision metering valve, bypass pressure regulation, and on-board electronic driver into a single rugged unit, reducing system complexity while improving control accuracy and reliability.
Engineered for continuous industrial duty, the LQ6 supports stable combustion, fast load response, and compliance with modern turbine emission and performance requirements.
Function and Operating Principle
The LQ6 precisely meters liquid fuel flow to the turbine combustor by controlling a rotary metering valve through an integrated electronic driver. Resolver-based position feedback enables closed-loop control with rapid response to load changes, ensuring consistent fuel delivery under dynamic operating conditions.
The built-in bypass regulator stabilizes fuel pressure upstream of the valve, minimizing disturbances caused by supply pressure fluctuations.
