  • 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.
