Nox Reduction Methods

During the last century, Nitrogen oxide emissions, called NOx, have constantly been increasing. Due to the destructive effects of nitrogen oxides on the health of

Dual Fuel Burners

RLGB-Series Raadman Burner

Applications

Raadman gas and dual fuel burners are suitable for the following utilizations.

  • Installation on heat exchanger
  • Hot water boiler
  • Steam boiler and high-pressure hot water boiler
  • Hot air generator
  • Compatible with all types of combustion chambers according to EN303 standard.

Emission

The emissions have been measured in various models at the maximum output, according to DIN-EN 676 and DIN-EN 297 standard.

The values of CO and NOx during burner operation are lower than 30 and 120 mg/kWh at 20 % excess of air for normal versions and, lower than 20 and 80 mg/kWh for Low NOx versions (LN series). consequently, the burner’s NOx class of II and III is reported and being approved for normal version and LN Versions respectively.
