Radiant tube

Radiant tube

A single ended radiant tube for furnace heating has four concentric tubes 10, 12, 14, 16. Fuel gas is fed through tube 16 and combustion air through the space between tubes 12 and 14. Flame and combustion products flow first in the same direction as the gas and air and then reverse at the end of tub...

Zusammenfassung:A single ended radiant tube for furnace heating has four concentric tubes 10, 12, 14, 16. Fuel gas is fed through tube 16 and combustion air through the space between tubes 12 and 14. Flame and combustion products flow first in the same direction as the gas and air and then reverse at the end of tube 12 to flow in the opposite direction between that and tube 10. The combustion air is caused to flow in a helical pattern by the provision of helix 36 so as to provide an extended flow path for better heat transfer.
