diy oil tank evaporator question

[pathfinder22]

Seems like almost the same set up pan wise, I have a preheater on the back shelf slow dripping into the pan to maintain level.
It is fitted only for 6" stack and no blower,,, YET!
This is a new cooker, I figured I would have to make some tweaks....
Something to work on for next year.
I will be boiling again saturday, and will be adding some stack to the height, it should make some difference.
My old barrel cookers I made would shoot flames out the stack..was great for roasting hotdogs on a stick...lol
Thanks for all the info guys.

What is your air supply under the grate?

Just the slide vent need the bottom and the door open a little, hence the drafting problem.
I will probably take the vent off and add a small blower next year, no time to
mess with that right now though.

just a little update, I added another 4' of stack saturday, total about 7 feet straight up now.
it helped the back pan boil a little better, only about half of it.
It was easier to maintain overall temperature thoughout the boil though.
Really was hoping to get a higher evap rate then I am getting. the other issue is I pack it full of wood then
4-5 hours in I have to scoop coals cause it starts to block the vent.
well its a learning process, more stack height next season.

Here are some pics from my homemade oil tank evaporator. Under the door, we cut a vent for draft. The grate sits even with the bottom of the door, so all the air coming in the vent goes up through the grate. Burns really efficiently, very few ashes left after a boil.

That last pic is upside down, have no idea why . . . Sorry!
