More burner pics, per above discussion.
Close-up of a version of the "roaring" burner from K.N. Harris - uses Petrol, and because the air hole is on one side the flame is biased to the opposite side, not uniform. Actually quite a small burner, the 3" horizontal boiler needs a bigger flame than this can manage.
A Paraffin/Kerosene proprietary blow-lamp converted to blast a flame beneath a 3" horizontal boiler - As good as these get, but a bit small. Good for a marine boiler fire-tube, with cross-tubes.
2 of my 4 Regular blow-lamps, one petrol and one paraffin/kerosene, just sitting on the bench from a recent job.- can be bought for around £10~15 in the UK, and if any bits required for refurbishing pumps, valves, jets, prickers, these can be bought off £&@y easily.

Sorry to be a bore to those who are not interested - but you have managed to read to the end of my thread...
