Gas Brewing

[rukkus]

Not a clue, DarraghKS might know as he uses them. I'd love to know how quickly they'd get 70L up to boiling. I think i'd opt more towards a 20 jet one

The thread I was reading he had a 20 jet but had 10 of them blocked as he thought 10 was enough. No idea how big a boil he had though.

Some of these also look nice http://www.gasproducts.ie/acatalog/Centre_Fire_and_Vortex_Gas_Catering_Burners.html

I'll be moving my brewing from the gas cooker in the kitchen to a brew stand in the man cave in the new year, it's just too dangerous moving heavy pots full of hot wort around. I have nightmares where one of the handles gives way and I end up looking like Harvey Dent.

I'm thinking of getting a single tier brew stand made up from a welder out of box steel. I bought a couple of chuggers in the recent GB so they will be placed on welded plates. A couple of burners, maybe three, and a plate chiller are to be my next purchases. I'll have to sort out some type of ventilation system too.

Interested to see how you get on with the jet burners if you go for them. What's the benefit of LPG of natural gas? Or is it just that all bottled gas is LPG whereas piped gas is natural?

Jesus you fellas must be loaded burning all that gas

I have been doing a bit more research before buying a new burner and it seems the guys in Aus use the 8.8kw burner I already have for much larger boils than I'd be able to use mine for. From what I can see they use what they call a medium pressure regulator that goes up to about 2bar. Has anyone tried different regulators on the 8.8kw burners? Would the gas control valve on the base of the burner also need to be changed for this to be safe?

They call them the Italian Spiral burners over in Australia. My burner indeed says made in Italy and looks the same.

I was considering trying the 50 - 150 mbar regulator rather than going up to 2bar. I obviously don't want things exploding, can any gas experts comment?

Please consult with a professional vendors of these products as the potential for harm to you and or those around you when it comes to incorrect handling of a compressed explosive product cannot be understated

Yer bonkers to use gas to heat your liquor. Waste of money imo & you'll over shoot your temps every time. Much easier put an element or two in your HLT & cycle on/off the heat with an stc to hold your desired strike & sparge temp.

Gas for the boil is great. Im on propane with blichmann burner. Very efficient & great option for larger brew kits. Id highly recommend the blichmann burner. But the next best thing is linked below:

Thats the guts of the blichmann. You can get your local gas shop to fit a hose & regulator for you. Make your own stand.

Yea i really want to get my hands on a blichmann but getting one here is very difficult, i love the look of the banjos but they require a ton of work to build a stand etc

I don't find the burners to be very loud. They do use quite a bit of gas, but the more wort you make in one sitting the less gas you use in comparison to brewing a couple of small brews.
We didn't block any holes as we just regulate the gas valve to increase/decrease the heat. These are low pressure only when used with the lpg jets. These use 37mbar @ 2.5kg/hr. So get a regulator for that. We tried a stronger regulator with 9.2kw burners we had and it didn't help as the air flow was too limited by the burner. I think they actually do have limitations in terms of heat output.
I use this link: http://www.phpdoc.info/brew/boilcalc.html
to determine how long to ramp up through temperatures. Base all gas burners at approximately 33% efficiency of the full power of the burners and we get an accurate idea of how much power they actually have.
