Dammit, you started without me, I was on the phone.

 

Well the trench looks to be a soakaway, as it is deeper than the feeders. The square item at the top appears to be the source of what ever is draining. Might it be something to do with a field kitchen?

This is probably not a soak away as it breaks all the rules governing the design of such things, the broken lines may denote that those parts are hidden, under or behind summat, dunno what though

 

Whatever flows through would be logical to say it goes from A to B.

If the trenches/gulleys contained some sort of media it could be a filter system..

Looks like the layout for multiple cooking points from a central heat source???

 

Neil you are getting very warm(!) but have got something the wrong way round.

OK - a series of flues leading from heat sources to a central chimney??

The pit has burning dried dung in it, heat going up the channels / tunnels to an oven.

Yes Neil well done!

 

It is a gridiron kitchen (Aldershot pattern). As far as I can work it out. Trenches are dug in the ground. The deep trench is lined with clay & sculptured to fit cooking vessels & kettles, the fires are lit in the tapered 18" sections & the fumes are drawn away up the chimney.

Yes you certainly deserved to score Neil. Let me know if you want the full instructions if you are planning a weekend barbecue for instance. If you can't get any helpers, you'll need to start work on it right now:

Well done Neil for getting that one because I am still baffled.

 

It is a most peculiar setup, I am still failing to understand how a 4inch flue only about 8ft high could possibly create enough draw to pull smoke up 9 pipes each of a larger section, especially as the fires are 12' away from the ends.

 

How was the flow of smoke ever persuaded to start flowing through the flues instead of straight up like a proper fire?

 

Did the wind never bow? The slightest cross draught would upset eyery thing.

 

Even if it did work, what would be the point?

 

I'm baffled, any one got any thoughts on this?

 

Full instruction needed please Clive.....
