The 2″ Gas Metering Valve is designed to precisely control the flow of gas fuel in aero-derivative gas turbines, including the LM2500. By adjusting fuel delivery based on operating conditions, it maintains the optimal fuel-to-air ratio essential for safe, efficient, and reliable turbine operation.

Fuel metering valves act as the throttle control for gas turbines. Since turbines generate power by burning fuel mixed with compressed air, accurate regulation of this mixture directly impacts power output, efficiency, and emissions such as nitrogen oxides (NOx) and carbon monoxide (CO).

This valve delivers exceptional accuracy within ±1% of the flow point, ensuring consistent fuel delivery and optimal combustion. It is built to perform reliably in demanding environments and meets safety standards including ATEX, PED, and UL, certifying it for use in hazardous and extreme conditions.

The fuel metering valve is a two-inch right-angle style valve commonly used on aero-derivative turbines. It integrates easily into existing systems without requiring hydraulic or electrical changes. With millions of hours of proven field performance, it offers dependable, precise fuel control that enhances turbine efficiency and reduces fuel consumption.

The LM2500+G4 SAC 50Hz Combined Cycle 1x1 is a gas turbine system that combines a gas turbine with a steam turbine to improve overall power generation efficiency. This configuration captures waste heat from the gas turbine exhaust and uses it to produce steam, which then drives the steam turbine, generating additional electricity. This approach helps maximize power output while making better use of fuel energy.

Building on the LM2500+ design, the LM2500+G4 increases power capability by about 10% without reducing the lifespan of critical hot section components. This is achieved by increasing airflow, enhancing materials, and improving internal cooling. Despite these upgrades, the core compressor and turbine stages, as well as most airfoil and combustor designs, remain consistent with the LM2500 model.

The LM2500+G4 features a 17-stage high-pressure compressor that raises the engine’s pressure ratio and airflow, boosting the total power output of the gas turbine to over 31 MW. It uses a Single Annular Combustor (SAC) equipped with water injection to help control emissions while maintaining stable combustion. The SAC’s simple, proven design provides uniform flame temperature and reliable operation.

This balanced system is common in industrial and energy applications where efficiency and power output must be optimized, especially under varying ambient conditions. The combined cycle setup offers a reliable and efficient solution for electricity generation in demanding environments.

The LM2500+G4 SAC 50Hz Simple Cycle is a fourth-generation aeroderivative gas turbine of the LM2500. Designed for industrial power applications, including those in the oil and gas sector, it delivers more output and greater thermal efficiency while retaining the ease of maintenance and high reliability the LM2500 series is known for.

In a simple cycle configuration, the gas turbine generates power directly by expanding hot gases through the turbine stages, without recovering heat for additional power generation. This design is favored for its simplicity, lower capital cost, faster start-up, and suitability for mobile or remote applications.

The LM2500+G4 improves upon its predecessor by increasing airflow and turbine cooling capacity, allowing for higher operating temperatures. These changes result in up to 40% thermal efficiency in simple cycle mode—an impressive figure for this class of turbine. This translates to improved fuel usage and reduced operational costs over time.

The engine features a Single Annular Combustor (SAC), which supports stable combustion with low emissions of nitrogen oxides (NOx) and carbon monoxide (CO). The combustor is also designed for durability and long life, with easily replaceable fuel nozzles and a thermal barrier coating for resistance to high temperatures and corrosion.

Its two-spool design means the engine has no cold start limitations, making it well-suited for harsh or variable environments. The power turbine and gas generator can be separated, allowing for easier in-module repairs and less downtime.

Overall, the LM2500+G4 SAC 50Hz Simple Cycle offers a balance of power, efficiency, and maintainability, making it an attractive solution for power generation and mechanical drive needs in industrial, onshore, and offshore oil and gas operations.

The LM2500+ DLE gas turbine is designed to provide reliable, efficient while meeting strict environmental rules. Ideal for power plants where emissions limits and water availability are critical concerns, the LM2500+ DLE provides clean, flexible, and high-performance power generation.

Using advanced Dry Low Emissions (DLE) technology, it reduces nitrogen oxide (NOx) and carbon monoxide (CO) emissions without requiring water or steam injection. This makes it especially valuable for facilities aiming to minimize environmental impact and avoid the operational complexity and maintenance costs associated with water-based emissions control systems.

The turbine’s ability to maintain NOx emissions below 25 ppm on natural gas—and as low as 15 ppm under certain conditions—ensures compliance with tough air quality standards.

With a power output exceeding 31 megawatts and thermal efficiency above 40%, the LM2500+ DLE suits a broad range of applications, from utility-scale electricity generation to industrial cogeneration and offshore power. Its fast start capability and robust cycling performance enable it to respond quickly to fluctuating grid demands, making it an excellent partner for integrating renewable energy sources.

Fuel flexibility extends the LM2500+ DLE’s usability across different operational contexts. It runs smoothly on natural gas, diesel, aviation fuels, and even hydrogen blends—offering operators confidence and versatility regardless of fuel availability or market conditions.

Maintenance is simplified thanks to the turbine’s modular design, allowing rapid access and part replacement. This reduces downtime and keeps plants running efficiently, enhancing overall productivity.

Combining power, efficiency, emissions control, and fuel flexibility, the LM2500+ DLE supports effective and compliant power generation in a variety of operational settings.
