Barbie core? Horiz one!

[satamax]

Hi everybody.

Since some of you have the hang of horizontal batch rockets, i thought i'd ask about your advice. Would you think this one could work as a barbecue core?

Held in a barrel, by the presure of the vermiculite, a very light bottom of castable and vermiculite on the bottom of the vertical row. May be a slight joint on each side where there's a slight gap. Trying to make it the lighter possible. I've used a 1/3 of the csa of the riser, as 60% or 70% would be too big imho. It's meant to be topped either with a cast iron plate or a grate full of volcanic stones, same as gas barbecues.

Sketchy in the following post.

Here's the sketchup.

Max,
This could work, but the port 33% of the riser csa would be too cramped I guess. Of course you could try it at first, in order to find out the best port dimensions.

Hey Peter, i will see. But i'm afraid making it 60% or 70% would be too big and square, not bringing enough turbulence.

Thanks a lot for the reply. The idea behind the big heat riser elements is that they are flat, so the end of the burn tunel is already made. Instead of casting, like the last time i tried with the stove and round elements, the cast concrete separated and expanded cracking the burn chamber element.

Max, internal dimensions aside, I think you will be pleased using a horizontal core as the heart of an outdoor cooker. I've been sitting around mine almost every night making unbelievable food on that thing. If I may make a suggestion, I would strongly recommend you encapsulate the whole thing in a barrel, with a proper top gap over the riser. Put an exhaust flue low on the barrel, just above the firebox, and put a hole in the top of the barrel about 4" in diameter, right over the center of the riser. In this way you can use a steel baffle to precisely control the heat from the riser to whatever you put on top. You can then set a small BBQ, large pot of liquid, cast iron griddle, etc. on top. It's very versatile and incredibly useful. I seriously haven't cooked dinner inside in almost a month.

Here's a short example of the cooking burner.

So guys, i've bought the only 30cm element he had left and a pair of 18cm, square ones for the heat riser. Recuperated 4 clean barrels too. Will see how it goes, plans have to be modified! Again!

Soo, here it is!

Stuffed vermiculite to hold the parts. It's a lovely fit imho. I don't have enough lava rocks as of yet, two bags is not enough. But i think tomorow, it will get a first proper burn.
