The LM2500 is a multi-shaft gas turbine featuring a free-spinning power turbine, making it well-suited for dynamic and high-demand environments such as those found in oil and gas operations. In this design, the high-pressure turbine and compressor are mechanically independent from the low-pressure power turbine. This separation allows the power turbine, which drives the electric generator or mechanical load, to respond rapidly to changes in load demand. Its ability to accelerate quickly makes it ideal for applications where maintaining grid stability or mechanical output is critical. In scenarios where frequency fluctuations occur, the free power turbine can quickly compensate, helping to stabilize the grid and ensure smoother operation of all connected systems.

In its standard configuration, the LM2500 is equipped with a six-stage, low-speed power turbine. This turbine operates at a nominal speed of 3600 rpm and is designed to deliver reliable shaft power in steady-state conditions, making it particularly effective for electric power generation or mechanical drive in pipeline and process operations.

For applications requiring greater flexibility or higher continuous output speeds, the LM2500+G4 variant offers enhanced capabilities. It is available with either the standard six-stage, low-speed power turbine or an alternative two-stage high-speed power turbine. The high-speed variant is engineered for mechanical drive and other demanding industrial uses, with a design speed of 6100 rpm and an operating range from 3050 to 6400 rpm. This configuration supports continuous high-speed shaft output where needed and is particularly beneficial for compressors and other rotating equipment in oil and gas facilities.

Both the six-stage and two-stage power turbines can be operated over a cubic load curve, providing the adaptability required for variable load profiles commonly encountered in oil and gas operations. This flexibility, combined with the LM2500’s rapid response characteristics and modular design, makes it a dependable choice for critical infrastructure in upstream, midstream, and downstream sectors.

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 T5.4 thermocouple is a temperature-sensing probe used in LM2500 gas turbines to measure exhaust gas temperature (EGT). The label T5.4 refers to its specific position in the turbine\'s exhaust thermocouple array—zone T5 (turbine exhaust), sensor 4. These sensors are part of a system that monitors thermal conditions at multiple points in the exhaust stream.

This thermocouple operates in high-temperature environments, withstanding continuous exposure up to approximately 1100°C. It is built to maintain accuracy and reliability under the thermal stress and vibration typical in gas turbine applications.

T5.4 thermocouples are often used with flexible

harness systems. This allows operators to replace individual probes without removing the entire harness, improving maintenance efficiency and reducing downtime.

By providing real-time exhaust temperature data, the T5.4 thermocouple supports engine control, performance optimization, and safety monitoring in industrial gas turbine operations.

The LM2500 High Pressure Turbine (HPT) Vertical Stand is a support fixture designed to hold the HPT module of the LM2500 gas turbine in a vertical position. It is mainly used during maintenance, inspection, or transport of the turbine module.

By keeping the turbine upright, the stand helps ensure that the module stays stable and properly aligned while work is being done. This setup also makes it easier for technicians to access certain areas of the HPT that would be harder to reach if the module were lying flat.

The stand is built to handle the weight of the HPT and includes features like mounting points or forklift slots for safe and easy movement within a workshop or maintenance area. It is commonly used in the oil and gas industry where LM2500 turbines are found in power generation or mechanical drive applications.

In short, the HPT Vertical Stand is a practical tool that helps keep the turbine secure, makes maintenance tasks safer, and supports good handling practices.
