Hi all


I have read in the book of Ianto and Lesly.

These people state that the burn tunnel needs smaller then the rest
of the ducts.

I can put stones 3 cm thick on bottom, and than have also a ashpit.

then the burn tunnel get 3 cm smaller in hight. Because it needs
to be smaller then rizer for example. I do follow book here.

The size of the cross-sectional areas of
all parts of the stove’s internal ducts should never
decrease below that of C. In other words, the cross sectional areas
of F, G, H, J, and k should all be greater than that of C.
C is the burn tunnel.

I can see some agrees here, because it sucks better and burn better that way.

Hi Glen and Scott.

I have a sound who was blasting fire because of to much draw when  put extra length on river.

The stink came from smoke, I do smell woodstove stink, I do not want.

For Glen, I have a barrel with a opening on front, when make the feed to long I can not put wood in it,
so did 25 cm long, the river is now 100 cm, that is 4 x feed, can not do more, so feed is now 24 cm..

I have follow the dimensions, the burn tunnel rizer and feed is all 6 inch. Because of barrel dimensions
inside I can not do make burn tunnel longer then max 46 cm edge to edge, with stones 3 cm each
it is 52 cm, that is exact the barrel width.

When I measure from middlepoint like peter do I get feed 16,49 cm burn tunnel  32 cm, and rizer should
be then 66 cm if I am right.

When measure from the edges I get feed 24 cm burn tunnel 47 cm and rizer should then need 100 cm
is this right?

It burn better when make rizer higher, but to high it get to much draft.

I test with upper barrel removed.

thanks.

Have redrawn system a little, I have now use  feed 24 cm,  tunnel 46 cm, and rizer 100 cm.

I have increase the feedtunnel length to 24 cm, is now 20 cm.

That is the advice I see on this forum, I have also use rizer = 4 x feed.

if it works oke, I need not t smell bad things, now I do.

measurements are all from the edges.

I have test the rocket heater.

Do not perform well, stinks.

Maybe the dimensions, special the vertical tube, do these need as big as the feed and rizer?

How to measure lengts? Read different stories. I have 15 cm opening, the whole system, a
longer pipe on the rizer did cause fire shocking sound.

I like brittisch cars, most because of the nice warm interior.

It is a 3500S indeed, without any bad body rust, most is still in manufacturer colour.

This is a very healthy car.

I am working now around it, busy with the breaks, and special the back calipers are a big pain
in the a$%.

But now back to on topic.

Thanks Nancy,

See you are a automobile engineer.

Then you like this also.

Hi all.


I have now secure the rizer into the barrel and mortar the gaps so it is not leaking.

Can be tested but nabure will protest, even when there is no odor or smoke.

She is anti woodfire.

The mortar I have is to coarse to use it, need a 8mm gap between stones.

There is also mortar gleu in a bucket, I think this is better, the stones need to stick strong together.

some tips maybe.

thanks.

8mm in most cases for fire brick mortar is WAY TO THICK

your fire brick mortar should indicate a very thin gap  of 1.5 to 3 mm to be used, and in general  this type of "glue as you call it" is very sticky.  I have never seen coarse fire brick mortar?   But perhaps you have something like that over there.

it has been suggested often the use of fire clay and sand mixture, but again, I doubt if that is suggested to be used up to 8mm.  I don't mind to be corrected. But if you do have gaps up to that much, I suggest you cut your bricks to be tighter.

Hi scott,  I did say this 8 mm because I had mortar with perlite in it and not very usable for gleu the bricks.

I have use a tube ready to use mortar who has just a layer of 1 a 1.5 mm  and did build the core now that way, it is very strong.

I am now here, I do work on it between other work. But it begin to get shape.

Filled paprika's, the Serbian way, very tasty with french bread.

Serbian white bean soup is also a good tip.
