Low Nox Regenerative Ceramic Burner (RCB)
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.
