New meth stove with some control.

[singteck]

Simple meth stove usually run out of fuel too early or contains too much fuel which will be wasted.


I made a small addition to solve that problem.

Works fine but the tube gets a bit hot.

Interesting design there Singteck

 

[Wayland]

Interesting idea...

 

[Clouston98]

Very clever idea mate .

 

[singteck]

Still experimenting. Think I will need a longer brass tube.

Thats genius - nice to see you back on the forum

You keeping well mate?

 

[Macaroon]

Good thinking - keep us posted on developments please

Nice one. Silicon tubing would be good as it's heat resistant. How about a gravity feed?

I have a couple of remote feed stoves, the,y work quite well

Nicely made, I've always thought of getting my hands on an IV drip tube, they have a controllable flow rate. Kudos.

Thank you BR! I am very well.

I am always around.... just not posting much.

Gravity feed will not work because of the gas pressure in the chamber. Will be working on a pump and valve system soon.

IF you use stainless instead of brasa youll see a lot less heat transfer.

That is true, but stainless steel will be too difficult to drill with such a small hole.

So far I have ran it for 20 minutes.... ran out of time and not fuel.

Tried using petrol in it as well..... too much smoke and probably too much toxic! But just want to know......

Petrol? You're a mad man.

Good idea (not the petrol, too reactive imho) a bit like the gas burner for the trangia.

Very clever your defo onto something their .if I can be dumb enough too ask what stop the flame creeping up the tube

I think basically there is not enough oxygen in the chamber: fuel + heat + oxygen = fire. In the chamber liquid meths is getting heated and turning into nice hot and very combustible vapour, when it escapes it hits the air and burns nice and clean. That vapour inside is squeezing out any air, denying itself the chance to combust before it escapes!

I think that's right and I think that's why if you look at a primus/msr stove the fuel pipe runs close to the burner to pre-heat the fuel. Also why your gas hob only burns in the same manner.

theres a few controllable designs around now....

Oxygen in a fuel vapour oxidise mix. Why will wood not spontaneously combust because you have to heat it to a point of combustability with an oxidiser present ( smoke n air). You only burn the vapour.


Also the only petrol that works in trangia is acetone, very hot, do not put it in your multifuel,

 

[singteck]

A continuation of the idea. What do you think?

You can continue cooking non stop as long as you top up the fuel.

Here is a video I uploaded to youtube to show how it works.
