The LM2500 DLE Gas Turbine is an advanced power generation unit designed to deliver high efficiency while significantly reducing emissions. Utilizing cutting-edge Dry Low Emissions (DLE) technology, it precisely controls fuel and air mixing to minimize nitrogen oxide (NOx) emissions.

The LM2500 DLE utilizes a single-rotor gas generator with a 16-stage compressor and a two-stage high-pressure turbine, coupled with cutting-edge DLE combustion technology to reduce nitrogen oxide emissions. It supports dual-fuel operation on a wide variety of fuels, including natural gas, diesel, aviation fuel, LPG, and even hydrogen blends with concentrations ranging from 5% to 95%. The turbine’s open configuration allows for faster maintenance and quicker engine replacement, minimizing downtime.

Its key benefit is utilizing advanced aeroderivative gas turbine technology with dual-fuel Dry Low Emissions (DLE) capability, achieving ultra-low emissions of just 15 ppm NOx on gas fuel, combined with broad fuel flexibility—making it ideal for meeting strict environmental regulations while providing fast, reliable power for dynamic grid demands.

The 3” Globe-Style Gas Metering Valve is designed to deliver accurate and consistent fuel control in industrial gas turbines, including both Dry Low Emissions (DLE) and Single Annular Combustor (SAC) engine types. This valve ensures that the correct amount of gas fuel is metered into the engine based on real-time operating conditions—essential for achieving stable combustion, optimal turbine performance, and reduced emissions.

With an accuracy of ±3% of flow point and a full-stroke response time of 175 milliseconds, it supports precise adjustments to the fuel-to-air ratio, even under fluctuating load conditions. This level of performance is critical for maintaining turbine efficiency, lowering NOx and CO emissions, and supporting regulatory compliance.

The globe-style design allows for smooth fuel flow control, making it ideal for high-capacity, high-pressure turbine applications, such as those found in the oil and gas industry. Built to withstand extreme temperatures and pressures, the valve is available with certifications such as ATEX Zone 1 and 2, PED, UL, and NEC Class 1, ensuring safe operation in hazardous environments.

This metering valve supports modern turbine control systems and is part of a generation of components that prioritize long-term reliability, reduced maintenance needs, and consistent field performance.

The 4″ butterfly bleed air valve plays a crucial role in controlling the flow of compressed air, called bleed air, from the compressor section of a gas turbine. This airflow regulation helps maintain safe and efficient turbine operation by managing pressure and protecting internal components.

This valve is built with a strong bearing shaft and specially designed bearings that handle frequent cycles, ensuring a longer service life and less maintenance. It includes a fail-safe feature that automatically opens the valve if a problem occurs, protecting the turbine from damage. With a quick response time—fully opening or closing in less than 320 milliseconds—it reacts fast to changing engine conditions. The valve’s electric components are also better insulated from heat, improving reliability even in harsh environments.

What makes the 4″ valve stand out is its ideal size and performance. It offers greater airflow than smaller valves, yet remains compact and easier to fit than larger ones, making it perfect for medium-duty applications where space and precise control are important.

Importantly, this valve is designed as a direct, plug-and-play replacement for existing models. It requires no changes to the hydraulic or electrical systems, allowing for quick upgrades without downtime. This seamless fit and reliable operation help ensure your gas turbine runs smoothly and efficiently, reducing costs and increasing uptime.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 is a high-performance gas turbine system designed for large-scale, high-efficiency power generation, particularly suited to the needs of oil and gas operations. This configuration links two LM2500+G4 gas turbines with a single steam turbine in a combined cycle layout—capturing waste heat from the gas turbines to produce steam and generate additional power. This approach significantly improves overall thermal efficiency while maintaining operational flexibility.

The Single Annular Combustor (SAC) with optional water injection helps the system meet emissions rules while keeping combustion stable and efficient. The LM2500+G4 improves on the previous +G4 model by increasing airflow, using better materials, and adding improved cooling. This allows it to produce about 10% more power without reducing the lifespan of critical hot parts. It can be equipped with either a two-stage or six-stage power turbine to fit different needs. Even with the higher power output, the +G4 keeps its modular, two-spool design, which makes maintenance easier and ensures reliable performance in many environments.

In the 2x1 configuration, the system delivers approximately 41% more power than a single gas turbine unit. The use of combined cycle technology ensures better fuel utilization, helping to reduce overall emissions and lower lifecycle operating costs.

The LM2500+G4 SAC 50Hz Combined Cycle 2x1 offers higher power, improved efficiency, and a flexible design, making it well-suited for large-scale oil and gas operations that demand reliable and efficient power generation. Its “50Hz” designation means the turbine is specifically optimized to supply electricity to grids operating at 50 cycles per second, ensuring seamless integration with regional power systems.

The Single Annular Combustor (SAC) version of the LM2500+G4 is designed for oil and gas applications that prioritize consistent performance, fuel flexibility, and emissions control—such as LNG facilities, gas processing plants, and pipeline compression, both onshore and offshore.

What makes the SAC version different is its simpler combustor design compared to dual annular or premix types. The SAC uses a through-flow, venturi swirler to ensure an even temperature profile at the turbine inlet, helping extend hot section life. It features individually replaceable fuel nozzles, a durable machined-ring liner, and a thermal barrier coating for better resistance to high temperatures and corrosion. This design supports both dry operation (with higher emissions) and water or steam injection to reduce NOx when needed—making it adaptable to site-specific emission regulations.

The LM2500+G4 SAC builds on the proven LM2500+ design, with approximately 10% more power. This gain comes from increased airflow, improved internal cooling, and material upgrades—while keeping the same number of compressor and turbine stages. The 17-stage high-pressure axial compressor and the basic engine layout remain unchanged, making it easy to maintain and service.

The engine can run on a wide range of liquid and gas fuels, allowing flexibility in remote or supply-constrained locations. It achieves up to 40% thermal efficiency in simple cycle mode. Water-injected operation enables NOx emissions as low as 25 ppm (gas) and 42 ppm (liquid).

In short, the LM2500+G4 SAC is well-suited for high-power mechanical drive and power generation in harsh or remote oil and gas environments, offering a balance of power output, fuel versatility, and emissions control.

The LM2500XPRESS gas turbine is a compact and modular power system designed for fast installation and quick delivery of power when speed matters. It comes prepackaged in 10 simplified modules, which makes installation easier and faster, with only 27 electrical interconnects to manage.

This turbine is based on the proven LM2500 aeroderivative gas turbine, known for its reliability and versatility. It can be used in a wide range of power generation setups, including baseload, peaking, simple cycle, combined cycle, and cogeneration (combined heat and power) applications. The system offers dry low emissions (DLE) and can operate on gas or dual fuel.

One important feature of the LM2500XPRESS is its ability to handle daily starts and stops without increasing maintenance frequency or costs. Its free-spinning power turbine design allows it to act as a synchronous condenser without needing a clutch between the turbine and generator, which helps reduce maintenance needs and downtime.

The turbine can ramp from a cold start to full base load in about five minutes, making it ideal for situations where fast power availability is critical. Its plug-and-play design allows industrial users or grid operators to connect and begin generating electricity quickly and efficiently.

In summary, the LM2500XPRESS combines a reliable aeroderivative gas turbine with a smart, modular package designed for rapid deployment and flexible power generation.
