Description

Fuel metering valves are the gas turbine’s throttle control. Industrial gas turbines generate power from the expansion of hot gases when fuel is burnt in the compressed air. The proportions of the fuel and air mixture decide how much power the gas turbine delivers. Accurate and consistent fuel metering is vital to a gas turbine’s efficiency and reliability.

Matters needing attention when maintaining the metering valve
 

1. The fuel metering valve is worn or stuck due to the failure of the fuel system oil circuit itself, such as fuel quality, fuel pump wear and other reasons. When replacing the new fuel metering valve, the entire fuel system oil circuit must be checked at the same time. Check, clean and replace fuel that meets the standards.

2. Because the huge pressure generated when the high-pressure fuel overflows may cause serious damage to the skin and eyes, and the leaked high-pressure fuel may be ignited when encountering high-temperature parts of the engine or the exhaust system, and there is a danger of fire. Therefore, when performing any operations on the high-pressure fuel system including fuel metering valves and its corresponding components, the disassembly and assembly specifiions provided by the manufacturer must be followed.

3. Never disassemble or assemble the fuel metering valve when the engine is running.

4. Before checking and disassembling high-pressure fuel components, make sure that the residual fuel pressure has been completely eliminated.

5. The high-pressure fuel system can be overhauled only when the engine is cold. Pay special attention to this when you need to disassemble high-pressure oil pipelines and parts.

6. There are two types of fuel metering valves: normally open and normally closed. Pay special attention to them during maintenance.

7. In the process of disassembly, inspection, transportation and installation of the high-pressure fuel pump or fuel metering valve, care must be taken to avoid improper load and to protect the relevant fuel interface.
