FR is a nozzle mixing burner that can be used to burn a variety of gaseous fuels such as natural gas, ethane, propane, etc. The integrated heat exchanger function recovers the waste heat of the flue gas and uses it to preheat the combustion air, thereby reducing natural gas consumption. The flue gas is discharged from the burner end, and there is no need for an additional flue in the furnace. The structure of multi-stage air supply can reduce the temperature of the combustion flame and suck up the flue gas in the surrounding furnace at the same time, which is conducive to reducing the generation of NOx and meeting the needs of rapid furnace temperature uniformity.

FR furnace re-coup burners are suitable for direct heating with an open flameThe heating furnace and heat treatment furnace can also be used for indirect heating with radiant tubesHeat treatment furnace. At the same time, when the furnace temperature is higher than 850°C, it also has flameless combustion ability. Compact structure, convenient for overall maintenance and installation.
