  • Product Overview
  • Related Resources
  • Applications
  • Self-supporting, high-temperature stainless steel assembly eliminates common “element sagging” issues
  • An exclusive Retro™ fuel injection system enhances turbine exhaust gas (TEG) and fuel mixing for optimal flame control
  • Flame stabilizing system (with TEG staged cooling zones) assures reliable, low-emissions performance and extended burner life
  • Complete CFD analysis, design, and fabrication of TEG flow correction devices, including distribution grids, turning vanes, and anti-swirl systems


Our innovative flame stabilizer system with a two-zone fuel manifold generates uniform combustion and even heat distribution to fit any HRSG configuration. Cleaver-Brooks in-house simulation experience allows accurate and complete modeling of the turbine exhaust flow, distribution grid, combustion, heat recovery system, and selective catalytic reduction (SCR) performance.


Improve Boiler Performance by Replacing the Burner →

In this webinar, attendees will learn the benefits of upgrading their boiler with a new state-of-the-art burner to improve boiler efficiency and better match facility needs.

Parallel Positioning and O2 Trim →

Parallel positioning controls help a burner to optimize its fuel-to-air ratio by using dedicated motorized actuators for the fuel and air valves.
