Note:

The LM2500+G4 SAC 50Hz Combined Cycle 1x1 balances capacity and efficiency by combining a gas turbine with a steam turbine. This setup captures waste heat from the gas turbine to generate additional power, optimizing fuel use while maximizing power output.

Executive Summary

The LM2500+G4 SAC 50Hz Combined Cycle 1x1 is a gas turbine system designed for industrial and energy applications in the oil and gas sector. It combines a single LM2500+G4 SAC gas turbine with one steam turbine, using advanced Singular Annular Combustor technology to ensure low emissions and reliable operation in varied conditions.

The system captures waste heat from the gas turbine to produce steam, which then drives the steam turbine to generate additional power. This combined cycle configuration provides balanced capacity and improved efficiency, making it well suited for both onshore and offshore energy facilities requiring dependable and cleaner power.

Detailed Description

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.
