Huge BTU natural gas burner for forge/foundry/pot/keggle

[slyker25]

Was that the gas from your biodigester?

[HomeDistiller]

@slyker25 nope natural gas from the gas mains

thank you for not dumbing it down.

This is really awesome. I just had an urge to make my own burner for outside cooking -- like high-heat cooking like I've seen done in Chinese restaurants with woks. I figure the only way to stir-fry like that at home is if I have a big burner outside. Yours looked like it might almost power a hot air balloon! What is the purpose you built it for, and can you give any tips?

[HomeDistiller]

@MetaSethical i built this for heating a 140ltr pot for home brew, and with a larger single nozzle for a forge and foundry. first you need natural gas not propane. if you have propane then you dont need the air blower as the gas pressure is high enough for a venturi system to work. natural gas is about volume not pressure so you need forced air to get it to burn clean.. but this type of burner will work great with a wok.. but you will need a thicker wok than the thin ones you normally find

[MetaSethical]

@HomeDistiller Thanks for the info. I've never made a burner before, but if it's just the simple idea of even distributing the gas and the air, and making sure to allow a method for blending the two, I can probably come up with something that will work well. Do I need any special metals? I figured for a big wok flame, it needs to be a ring of fire with lots of velocity coming out of the holes. Am I right in that thinking?

Thanks.

@MetaSethical no most large wok burners is one single large jet (see my prototype videos) the reason is most of the heat should be at the bottom most part of the wok as thats where all the food/oil etc is.. a ring makes a poor wok burner as it heats the outside to much and burns the sauce (trust me on this one im a chef by trade). you need to make sure you have nothing but expanding pipe (or at least straight) after the gas get injected or you will have back pressure (look up the venturi effect)

thats awesome. u just gave me an idea to build an outdoo gas lamp. would u be able to put a regulator on the tank or wherever and be able to make one that way? tell me whatcha think!

[HomeDistiller]

@Pupdawg9724 what type of gas are you using? and what do you mean by lamp? if you mean a light source then you will need a mantle of some type (something for the blue clean gas flame to heat to white hot to throw the light)

[Pupdawg9724]

@HomeDistiller

good point. yeah like either a street lamp with themantlesor just a decorative maple leaf kinda flame like ssome people have on their fron porch,you know. im sort of a freak when it comes to gas lighting so it was just a thought. And nie vid!

[97trainman]

Awsome! Talk about superheating a boiler.

[rolex285]

sehr Guht .....Mui Bien

[HomeDistiller]

@rolex285 yup

[TheYouwillsuffer]

nat gas burnes. aka,  super cooker.

[butkatrello]

I made a wood burning one out of an old propane tank, with a inflater pump, wook's real well. burns wood up fast

[ballonman124]

i'm guessing that il melt just about anything?

[MRdetination]

I want one, and won't the pop rivets melt from suck high temp? i thought they might because they are alluminium and that melts at a low temperature for metal, other than that you have built yourself a bloody good burner, could you possibly run it off a gas bottle like the ones that power a bbq?

[HomeDistiller]

@MRdetination they haven't melted because they have air being blown over them and the burner itself wont get that hot... if you are going to use LPG (bottle gas) then just use a venturi system and you can get a better efficiency with that because you have the pressure in the bottle. natural gas has very low pressure so you need to use forced air

[MRdetination]

@HomeDistiller ok thanks for the reply because i was thinking of using the same burner system in a furnace im going to built to melt a heap of alluminium i have once again thanks

[bunyabbie]

holy phuck man thats some cazy shit going on there!!! hope you have good insurance :)

[rabbitfish2222]

wow

[sloppi1234]

i nmight sound a little stupid but.. wont the flame get in the pipe into the main gas pipe? REPLY

[HomeDistiller]

nope as gas needs oxygen to burn, if it could do that then any burner would do it

[c3h89]

@sloppi1234 Not beyond the union of the oxygen and fuel lines. The oxygen line has no fuel, hence no fire, and the fuel line has no oxygen, hence no fire.

[DominickBlack]

LOve it!

[Hamish121212]

Bloody hell - that is a huge flame!

[HomeDistiller]

with fire bricks acting as a refactory i can get 8 kW's into the water now :) so yeah its a huge HOT flame :)
