Note:

The LM2500+ DLE in a 1x1 combined cycle setup uses exhaust heat to generate additional power. It\'s used in industrial plants, utilities where fuel savings and lower emissions matter.

Executive Summary

The LM2500+ DLE Combined Cycle 1x1 system combines one gas turbine and one steam turbine in a compact configuration that shares a common generator, maximizing power output from a single setup. With Dry Low Emissions (DLE) technology, it delivers high thermal efficiency—typically exceeding 50%—while keeping NOx and CO emissions low without requiring water or steam injection.

This configuration is ideal for power producers seeking efficient, lower-emission energy in space-constrained or water-limited environments. Its flexible, high-performance design makes it a strong fit for industrial plants, utilities, and combined heat and power (CHP) applications.

Detailed Description

The LM2500+ DLE in a 1x1 combined cycle configuration—one gas turbine, one heat recovery steam generator (HRSG), and one steam turbine—delivers significantly higher efficiency, exceeding 50% in combined cycle mode.



Designed for high thermal efficiency, fast start capability, and reduced emissions, the LM2500 family is widely used across onshore and offshore environments, including industrial plants, pipeline stations, CHP systems, and utility-scale power production.



The DLE combustion system enables the LM2500+ to maintain low NOx and CO emissions without the need for water or steam injection—simplifying operations and reducing water-related maintenance.



Key features include:

  • Triple annular combustor design for even temperature distribution and lower emissions across the power range
  • Electrically actuated DLE fuel valves replacing traditional electro-hydraulic SAC valves for better control
  • 75 pre-mixers in 30 external modules, creating a consistent lean fuel/air mixture
  • NOx emissions ≤15–25 ppm and CO emissions ≤25 ppm (on natural gas, full load)



With fast ramp-up—achieving base load from cold start in under five minutes—the LM2500 is an ideal choice for fast-start and cycling applications. This performance makes it well suited to dynamic grid environments and industrial use cases requiring quick responsiveness.
