New Envirotec Big Burn Pot

[farmerdanvg]

Hello all,

I've been burning with my envirotec for 5 seasons now, and I was in need of a new burn pot. The original one I find too small for cold days, and is cracked and the sides warped.
$12 of steel and 2 hours later, I had a new burn pot. It measures 8" x 6" and the burn pot is 4" deep. The sides are 6" high.









This is a #5 fire


The clinker rod works really well. Grab it with some vice grips, bang it against the ash bucket, and the clinker falls off. Bury it back in the corn and it's ready for next time. On another positive note, there is almost no fly ash in the stove now. Usually the door lip was full and there was charred corn on either side of the pot.

With no front or bottom, it should be easier to clean. It sits over the angle iron frame in the bottom of the stove... no modifications. I'm making a 5" wide one now for warmer weather.

Thanks for looking; if you have any questions or comments, don't hesitate to ask.

Hey, the pot looks great Dan. I've been burning for about as long as you, and same problem with my pot. I've purchased a replacement insert for one of my pots. You just grind off the welds on the top of the burn pot and replace the inner portion.

But, at the same time, I like the idea of the larger burn pot. My third stove, in the shop, was purchased used and the previous owner had constructed a large burn pot. It is basically a larger version of the original pot although with considerably heavier metal. I don't think it will ever warp or crack! He modified the angle irons on the base of the combustion chamber to keep the new pot in place.

I have a few questions for you though. One, it looks like you've left the backside of your box open, so it must be held tight against the back wall of the combustion chamber wall to force the airflow through the pot. Is that correct? Did you modify the angle irons on the floor of the stove as well? What keeps your pot in place when removing the clinker?

Thanks for the compliments, mdonkers.

To answer your questions, I have left the back and bottom open on the burn pot. It does have to be kept tight to the back wall to work; it sits surprisingly tight to the wall. When I take the clinker out, I just push against the front of the burn pot with the clinker rod that came with the stove as I grab the clinker hanger with pliers. If the pot moves, It doesn't go far.

The original pot would move on me as I would take clinker out. It slides about 1/8" fore/aft. I guess this is to allow the combustion air tube to fit into the hole. I never liked this, because if a kernel fell into there, it was game over, shut down the stove, vacuum, clean and replace the pot. I would put a piece of 1/8" thick aluminum angle wedged against the back of the pot and the front angle iron to prevent the movement.
Without a back on the pot, nothing can get stuck between the pot and stove.


I depend a great deal on gravity to hold the pot in place. I did not modify anything on the stove, mainly because I don't want to haul it out of the basement again.
10 hours at #5 on the feed, and the clinker is 3/4" thick.
