Now then...
I've made a few in the past from gas cylinders, as has everyone on here by the looks of it, but are there any hard and fast guidelines about what does and doesn't work?
F'rinstance - baffle plates. Should they be fitted horizontally just below the flue outlet or would a 45 degree angle be better?
If fitted at an angle - would you fit it so as to slope from the back of the burner down toward the flames, or the other way sloping up to the top of the burner?
Is there generally an ideal size for a baffle plate? Say... half the diameter of the burner body?
Air inlet vents - I know these are usually fitted to introduce air somewhere above the flame, but I've seen some bespoke stoves that have an inlet pipe running underneath and up inside, terminating in an outlet above the flame. I think the idea is to pre-heat the air going in so as not to lower the temperature too much and to encourage a secondary burn. I think
Flue diameter - Is there an established way of calculating this? I realise that a 2" diameter pipe wouldn't draw very well on say a burner made from a 17kg cylinder, but would a 6" diameter pipe be overkill? IYSWIM?
Lot's of questions I know, sorry for that. I'm just curious and nosey
