Why use a stove pipe

[plummaple]

Hey everyone,

Just built my first cinderblock evaporator and boiled some water yesterday!!! Man, was that FUN !!!! I have a cinderblock turned on its side, in the back of the evaporator so that the smoke has somewhere to go. The question that I have is there a huge adavantage to using a stovepipe chimney? Does it make the fire burn hotter? Thanks for your thoughts.

That is how you get your draft.

Also a stack may keep some ashes out of the pans.

it will increase the draft which increases the heat which will reduce the time to boil (the goal each year) and reduce the ash by quite a bit.

We ran pan on blocks for last 2 years and used an approx 8" x 10' stack. It helped. Does not hurt to add soil at a slope to back of arch to push heat up to bottom of pan


this coming year we are moving off of blocks and onto a 265 gallon converted oil drum for arch, add astck and will add small fan

You can wrap copper tubing arround the stove pipe and make real good preheater. Gerry
