Gas Burner

[baphomite51]

havent brewed in a while and my gas burner has been sitting around since december, i turned it on today and the flame was terrible really small but it is blue but it used to be huge i tried opening the lil silver part but it barely changed. there is some rust on it it wasn kept outside tho any suggestions? the bottle of gas is fine also. and knob is turned to full. its this one here got it from gasproducts.ie

here come the questions:

What gas are you using? Butane or Propane?

If Butane then what regulator are you using? For this size of burner I prefer the adjustable reg as opposed to the 37 mBar fixed reg.

The "silver bit" allows you to adjust the gas/air mix (like on a bunsen burner when you were in school)

The fact that you are getting a small blue flame meansd that you are not getting enough gas but the air mix is spot on!

Too much gas and not enough air gives a big yellow smokey flame!

I'm trying mine tomorrow. I just assumed it would work fine out of the box! Maybe I'll test it out first, before I mash in...

ok i took the lil gold piece off and there appeared to be something stuck in it, gave it a blow through and it cleared it out, flame seems to be fine now thank god, i was scared the cast bit had gotten clogged with dust or something. cheers for the help will_d but i am using a standard reg like the one pictured, why do u prefer adjustable? and im using butane

[Will_D]

Reason I like the adjustable is that you can get a bigger/bluer flame ( means more heat and less soot ).

37 mBar is a fairly low pressure. Depending on ambient temp the presure in a butane tank is a bit higher than that!

More gas = more air (due to venturii effect) = more heat

SOMETHING FOR ME TO THINK ABOUT IN THE FUTURE I HAVENT HAD ANY PROBLEMS SO FAR WITH REGARDS TO HEAT (feckin caps sorry) but maybe when im doing bigger volumes it could be a big help

Would one of these be suitable Will http://www.gasproducts.ie/acatalog/High_Pressure_LPG_Butane_Gas_Regulators.html

I'm looking to get one of those square gas burners and don't want to end up needing to get a 2nd regulator.

Yes the one on the right is the one I use. It fits the standard Yellow Kosangas bottle.

The one on the left is for a UK(&NI) Calorgas bottle.

Excellent. Going to get this ordered at the end of the week. Hopefully be able to brew next week.
