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.

I have not used any venturi

could you point out where i am wrong and what I can do to stabilize the flame so it emanated only from the delivery end

its a propane (LPG) burner. Nozzle size 5/32". Intended firing rate 8-14 Kg/hr

The Exam brochure clearly states that there is no procedure fpr re-evaluation

is there a remedy?

this is adversely impacting the child's career irreversibly
