I have built a gas burner in 3 inch steel tube with the firing end at perpendicular to the stem of the burner. I have tried various quarls (fins) at the firing end, even no fins at all. Whatever i do--- after some time--- 5-15 minutes--- the flame travels back and approaches the nozzle. Entire burner gets heated up in no time after this.

Intended firing rate 8-14 Kg/hr
