Industrial Burner K-RHGBERecuperated Gas Burner K-RHGBE

  • High-velocity burner with integral recuperator for heat recovery
  • Combination of recuperator and flame tube in one single component made of SiSiC ceramics (single stage combustion)
  • Compact unit in modular construction
  • Waste gas fitting, air and gas supply lines are situated on different levels and can be positioned 90° to each other
  • Burner control for automatic burner operation
  • Direct flame monitoring via ignition electrode (single-electrode ionization monitoring) or UV probe
  • Trouble-free direct ignition as well as instant burning stability
  • High technical level as regards functional reliability, energy utilization, emission of harmful substances and sound level
  • Large variety of possible waste gas, gas and air connections
  • Ease of maintenance thanks to simple construction modules
  • Smallest thermal wear and high resistance to aggressive chemicals
  • 100% back absorption of flue gases from the firing chamber possible upon direct heating
  • Available in 30 – 100 kW (100,000 – 350,000 BTU/h) in ceramic design
  • Combustion tube temperature max. 1260°C (2300°F)
  • For direct heating by means of ejector system to discharge the flue gases
  • For indirect heating by means of radiant tubes

NOXMAT®’s K-RHGBE high-velocity recuperated gas burner is designed for the direct or indirect heating of industrial furnaces in a number of applications.

The burner is available in either the “basic” or “complete” version. The basic version consists of: the burner, stopper for cooling air, connection fitting gas supply line, and connection fitting combustion air supply line.

The complete version includes: the burner, gas supply line with double solenoid valve VMR, combustion air supply line with solenoid valve VMR, air metering orifice, dynamic pressure switch, burner control NOXMAT-B, industrial plug, stopper for cooling air, waste gas tube + punched hole collar, and purge air line.
