Low Nox Regenerative Ceramic Burner (RCB)

Low Nox Regenerative Ceramic Burner

The Regenerative Ceramic Burner system was first developed into a commercial product in 1982 by Hotwork Development Ltd based from an original concept from British Gas Midland Research Station. This led eventually to the Queen’s Award for Technological Achievement in 1992. Thousands of Hotwork RCB burners have been used in a wide variety of applications (reference list available on request) such as steel reheating, forging, heat-treatment and aluminium melting, which positions Hotwork Combustion Technology Ltd. today as the most experienced designer of regenerative burner systems.

  • Outstanding fuel savings of up to 65%
  • Significant reductions in CO2 emissions (directly proportional to fuel savings)
  • Reduced levels of NOx
  • Rapid and uniform heat distribution
  • Robust burner with high turndown and excess air capability
  • Improved productivity
  • No need for refractory-lined flues or recuperator due to low exhaust temperatures
  • Reduced exhaust filtering requirements
  • Highly fuel efficient, compact system
  • Better resistance to heat and corrosion than metallic recuperators
  • Attractive payback period
  • Heat recovery by means of fast cycling compact regenerators working in pairs
  • Typical air preheat: 85% of furnace temperature
  • Staged combustion to reduce NOx levels
  • Velocities in excess of 90 m/s
  • Sizes from 300 kW to 6000 kW
