Active Burn Strip on AK 110

Active Burn Strip on AK 110

PostBy: heatwithcoal On: Sun Sep 22, 2013 8:42 pm

When my AK110 is idling (fr 0 at min 8) the leading edge of the burn strip is maybe 3" in front of back wall and the lazy blues are even with the back wall. I seem to recall on my other stokers the burn strip is more centrally located.
I have heard stories of the fire backing up into the hopper on other stoves.
Does this seem fine for this furnace or do I need to make an adjustment somewhere?
my draft is between .02-.03

The draft is a bit low, so I would check and make sure the baro is not open and set to .04. It is normal for draft to be a bit lower in spring and fall with the warmer out door temps. The fire however is right where it should be for idle.
Check out the draft issue and let us know what you find. Check all areas for blockage and let us know the chimney configuration.

Matt,

I have a cinder/clay chimney 10"x10" by 24' (i think). Coming from the stove i have 6" pipe to 6" elb to increaser to 8" to 8" straight vertical pipe to 8" elbs (2x) into 8" thimble throught foundation into exterior chimney. I am measuring draft in the middle of the vertical 8" pipe. One other question is the inside of the hopper is almost hot to touch. Below is a picture showing the interface between the hopper and back of the stove. The hopper is angled back away from the stove body with an air gap at the top but not at the bottom. Is this correct?

The back wall of the hopper can be as hot as 180*F, but not usually at idle unless the fan is not running. Your hopper looks to be angled away too much, check and make sure the carriage bolts are not up out of the slot thus allowing the hopper to tilt back. This could be killing draft by making a leak where the hopper joins the feeder.

Also you are taking the draft on the wrong side of the baro, need to take it between the bar o and the furnace, above will be affected by baro opening to a great amount. You didn't mention if the baro was open?

ARGHH!!! I was going from memory on the draft reading location. I am actually taking reading about 3" below the draft control on the 8" pipe. Should it be on the 6" pipe? The baro is set to crack at .04 and is now closed.

I will check on the installation of the hopper but I measured the hopper and at the top it is 1/2" from back of firebox which is driven by the angle iron running horizontal between the hopper and firebox at the top of the hopper only. The hopper is against the firebox at the bottom where it sits on the stoker mech.

House is tight, I duct taped together a 4" duct inlet to outside for combustion fan. Seems to be reading .03 now at idle now...48* outside... I did this for my previous stoves but did not install it on the ak110. Guess i need to add this as a permanent feature?

Thoughts?

The angle goes between the nuts and hopper, on the inside of hopper. Not between hopper and furnace. There should be a thin spacer between the hopper and furnace. The angle is a support for the sheet metal hopper.

As you mentioned, I have the large flat strip on the inside of the hopper with the angle in between the hopper and stove to be used as a spacer . When installing I seem to recall there being limited detail in this area of the instructions. Other stoves i have owned have an air gap between stove and hopper so I thought this should have one too. My bad, I should have made a call to the manufacturers, I heard they have top-notch service. :clap:
