Fine Tuning a Old Tri-Burner

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Today is the 1st time I started my refurbished Poineer top vent with power vent. I obtained a .4 draft setting the power venter at 3/4 rpm and adjusting the baro to obtain a .4 draft . The feed stroke of the carpet was set @ 5/8" but I was pushing hot coal over the edge. I reduced the carpet stroke to 7/16" with the convection/feed motor control on lowest setting. I have about 3/4" of cool ash at end of the grate. When I turn convection/feed motor to fast I had to back the feed rod nut to make the carpet stroke back to 5/8" to get the fire about 3" from back wall of stove. My question is if I set carpet stroke at 1/2" and only have less than 3/4" of cool ash at the end of grate and fire is 2 1/2 inches from back wall am I in the ball park? Does anybody here still have old school tri-burners and could someone give me help tuning my burner? Thank you in advance....

I think your instincts are good and you are in the ball park.

My first time with the Ol' Tri burner this season as well.

Mine pretty much stays 1-1/2" from the back and a good 3" of burnt off the front. I'm heating a Garage so I'm not nearly a fussy as I am with the house stove (but that's a 07 Channing III so you can't compare).

Thanks forthe replies. After all night burning on low convection fan/feed my cool ash on ther front of grate was about 1 1/2 inches with the carpet stroke at 3/8". 13lbs of coal in 12hrs.

What is you stove temp at that rate? 1lb per hr is awesome if it's meeting your heating demand.

stove temp @ 265/270. Its not meeting my heating demands in all rooms. I have forced hot air system in house with the fresh air intake in the same room as stove and I'm going to wire the circulating fan from the furnance to a timer to kick on at timed intervals to get the heat to my furthest rooms from stove and add a bathroom style fan in the coldest upstairs bed room on a variable control switch to draw warm air up. Will give a update in a couple days. Increased feed and fan rate to almost 2lbs per hour stove temp @ 300/320 all rooms are warm but rooms where stove is almost 85 need better air movement.

Can you run your furnace blower on low to help move air?

You know when people say it was "better back in my day"?

They were right.

2lbs, That sounds more like it. Very typical to move the warm air to the other parts of the dwelling via duct work and such.
You are very fortunate to a forced air system already in place, lots of us are heating "electric" homes with no such convienent ducting and are forced to be abit more inventive.

Sounds like you're well on your way, congrats.
