I saw this idea back in October at one of the BCUK Sussex meets, Monkey Boy showed me the burner, hence the title of this post, like many i think he wanted a better more economical way to use the Crusader Burner unit than using Green Heat or Hexi blocks.

The idea is incredibly simple and i really don't know why i never thought of it myself, now I've made no secret over the years about how carp the Crusader Cooker unit is and this fact is even backed up by the guy who designed it i believe?, but when I'm out and about and don't want to take a Trangia, Hobo stove or even have a small fire, i do use my Crusader Cooker unit, after all I'm not cooking anything on it, I'm just warming up some water that I've bought from home for a cup of tea or coffee, but in the colder months stuff like Green Heat just doesn't cut the mustard, i know some of the stove guys will say it never cuts the mustard, that's their choice, but i choose to use it.

This little burner unit though is so simple and so effective it's unreal and best of all, it's made from junk, the burner as you will see from the picture is a small Vaseline Lip Balm tin, which is filled with glass fibre loft insulation which in turn is kept in place by the wire mesh from a cheapo tea strainer, the whole thing weighs less than a gnats privates and sits in the burner tray of the Crusader cooker a treat, which coincidentally is where it lives when stored as well, as it's low enough to not interfere with the bottom of the metal mug when it's all packed away.

I cant store meths/alcohol in the burner though as the tin was prone to forming a vacuum, so i had to pierce a small hole in the lid in order to get it off, I've noticed the newer tins have a better design, so the hole is not necessary.

In use i filled the burner with meths so it was just starting to pool on the surface of the fibreglass, lit it and then put the mug, containing 500ml of cold water on the unit and put the lid on and in not too long a time the water was at a rolling boil, with fuel left in the burner.

I don't know how long it took to boil, as i don't work by the clock when I'm cooking or warming things up when I'm out and about, I've always worked to the ethos of "it's done when it's done", after all whats the rush, you are out there to enjoy yourself, there are just too many variables to consider when cooking outdoors, so i don't bother considering them.

So thanks to Monkey Boy for sharing the idea with me, personally i think it's brilliant

Interesting, how does it burn compared to just the empty tin with meths in?

no idea im afraid:(, never actually thought to try it, i have filled the Hexi Tray in the cooker unit with meths before though and it burnt out very quickly

I suppose it controls the evaporation of the meths through heat alone and less prone to spillage than an open tin. Nice idea, thanks

Do you think a tin filled with meths and then the lid put back on would work (but a circle of jets/holes on the lid) ?

Also i want to make on of these, what the stuff inside the tin called?

Thx

You'd have to secure the lid as the pressure will pop it straight off, a screw lid will work or some JBWeld on a conventional push lid, you'd have to fill through one of the holes though.

It's glass fibre loft insulation

Would anything else work like cotton/wool/fibreglass work?

Thanks again my friend :)

Fibreglass wick works well, cotton and wool would just burn up after the first go though. I've tried the stuff out of our loft which seemed to work okay, it stunk a bit though.

I've just snaffled a half empty tin of boiled sweets from the dresser draw, not much bigger than a shoe polish tin so it should work. We're off to Morrisons in a bit so I'll try and grab one of those tea strainers.

Looking forward to giving this one a try, cheers for the heads up Mark.

My loft has been converted so i dont think theres any available! Would rockwool work by any chance?

Yeah I reckon, try a bit with some meths on. That stuff is fire proof isn't it? If it holds on to the fuel it should burn okay.

Let us know

Give it try, as long as it's not combustable material in the can it should work fine
