Gas Metering and Regulating System for Gas Turbine
Gas metering and regulating system for gas turbine is a skid-mounted gas supply equipment for gas turbine in the compressor station of long distance gas pipeline, the system integrates the functions of filtering, heating, regulating, metering, venting, relief, leak alarm and automatic switching, having the characteristics of high explosion proof requirement, wide regulation range, good safety performance and continuous stable gas supply.
Application
Characteristics 3D The system presented here is composed of some subsystems, such as filtering and heating system, metering system, regulating system, venting system, gas leak alarm system and etc.
In a typical pipeline station the sequence is: Station inlet → Filtration → Regulation → Metering → Station outlet.
Scope of supply
- Of which, the regulating system has the features of “pressure control system ”, adopting the configuration mode of “safety shut-off valve + monitor regulator +self-actuated pressure regulator”.
- The metering system assembles with the flow computer used for the temperature and pressure compensation of the gas to calculate the flow rate.
- The venting system adopts centralized venting in principle, the gas leak alarm system can be interlocked with the main valve and venting system.
- When the leakage occurs in the operation field, the station control system will command the main valve to close and open the venting system to carry on the emergency venting.
- High requirements for the regulator in this system:quick opening ability and fast reaction rate（accelerating commander is provided in some situations）.
Capacity, design conditions and scope of supply are confirmed per project.
