ABSTRACT:
A system for the direct firing of immersion tubes for heating of liquids in vats or tanks, including a gas burner, of the postmixer nozzle type comprising a gas supply tube having a blanked off downstream end provided with a series of peripheral gas ports, the gas tube being concentrically disposed within an air tube and having a perforated cone attached thereto slightly rearwardly of the gas ports, the arrangement being such that gas and air is entrained above atmospheric pressure and thoroughly mixed at the burner head by the turbulent flow of air through the perforated cone and around its periphery so as to create regions of gas rich and weak mixtures whereby to obtain flame stability. The system also includes a combustion chamber communicating the burner with the immersion tube.
