The hybrid stove you built is functioning quite well indeed. Any thoughts to plotting a graph with various secondary air setting for the same time period on clear sheets and lay it over that graph like the old days back in school :D Your extended burns are nice, I remember when I started burning coal I would run down to the basement and mess around with stuff and I am sure I did more harm than good...what your doing is good now we need to find you a hobby for 15 hrs. :P

Actually I took the data points while I was at work. Love the remote ip cam haha. As for adding secondary air to a mature fire, I always seem to see the pipe temp increase and the over the load door decrease. I suspect the extra nitrogen carrying heat outweighs the benefits of burning CO on top the coal bed. It does however help maintain draft so I do keep a very small amount of secondary when I set it for the long burn. :D

Ok, you just gave me a couple ideas. 1, bi-metal, self adjusting over the fire air, and or, bi-metal self adjusting mpd. One thought I had is when the pipe gets hotter the bi-meal spring could adjust mpd to keep more heat in the stove :?: just a couple late night thoughts, talk to you later and stay warm!

I wish I could say the same. I am a bit of a newbie. My coals are burning but the temps in my 2600 sq foot home aren't steady. Some days I get low 60's sometimes as high as the 90's. I'm baffled. Why do my coals seem like they are burning cold? It's not feeling all warm and toasty like I know it has done in the past. I have a Harmon. It has an air flow adjustment in the front, ash shifter on the side, and on the pipe going into the chimney is like a swinging trap door barometer or something . My coal place accidentally gave me rice instead of nuggets, and I've noticed rice seems to last longer (nuggets i was using a bag and a half a day - rice about a bag or less a day). (I live in York PA).

When I get up in the morning, I do my ash shake until i can see the coals burning bright in the ash area, scoop a quart pot worth of coals, shake it on top of the barely lit coals until they are covered about 1/2 inch, open the bottom draft door in hopes that the oxygen will kick up the flames, and leave it for about 15 mins. When it seems the coals are taking, blue flames are dancing, I repeat the procedure until the stove has coal filled to the top of the back wall (upright brick top). Then, I leave it alone. Sometimes the coals die, other times they kick up.
Any suggestions or comments? I try to keep the ash pan low and cleaned. Temps are in the teens/20's lately.

Am I understanding correctly, you are burning rice coal in a hand fed coal furnace? If so, that may be the problem. Pretty much, rice coal is only for automatic stoker stoves. I'd call the coal guy and tell him he goofed and you need nut coal

Sweetczz , I'm surprised your able to get any heat or maintain a fire with rice , Carbon had a good suggestion about calling your supplier , have they deliverd to you before? Do you get bulk or bagged? Good luck , Shawn

I too agree with Carbon12. Get some "nut" sized coal. Some places are in short supply of nut. If so, ask if they have pea. Oliver

actually I ordered nut - pallet - so we unloaded and later that night i went to use it it was rice! However, it does burn well when i'm doing something right. Today i cleaned the stove good, burned a few logs, loaded the rice coal, left the house and came back to 83 degrees! No i don't have a self feeding stove, but it's an old Harmon. I'm guessing when it doesn't burn hot enough it just gets clogged even though we do shift and poke the fire. There were lots of white chunky pieces like maybe the rice should have burned hotter to make it more loose ashy. I'm actually loving the ease of use with rice, but the mess sucks - i use less bags too - a huge savings over coal!

You need nut coal, not rice. That's why you're having the burning problems you're having. Call the dealer and tell him to come get the rice. You'll be so happy you did.

I've used the nut and I think i had more waste with it - took almost 2 bags a day - now i can use a bag or less of rice coal - I may decide to buy some nut coal to add to my fire just before bed or before leaving since they're bigger chunks and might burn longer. But so far, so good.

since I cleaned out the stove and started new, I've been able to keep it stoking a steady 82 degs - after about 7 hrs it drops to about 76 and it's usually around the time I am ready to leave the house or go to bed so I will top it off. Because I got a good burn going again, the new coals take very quickly and strongly. It seems that the problem wasn't so much the wrong coal, but not cleaning the clogged uncooked coals from a weaker fire previously to the cleaning.

When the stove burns hot and efficiently, the ashes fall through the grate better and I am able to keep a good burn going longer. So, it was an unexpected surprise that rice coal does work. It's easier to manipulate and scoop, too. I use a KIRK brand 1 and 2 quart pot, scoop the coals, and my hands are protected when I dump them into the fire. I'm slowly relearning the art of coal burning, and learning new things by accident :)

I admire your exploration with the rice coal but I (like the others) believe this is the bulk of the problem.. Hand feds are designed to burn pea size and bigger. Rice size isn't going to give consistent burns because of the tiny pathways to carry oxygen throughout the coal bed.

sweetczz wrote:and on the pipe going into the chimney is like a swinging trap door barometer or something .
this is a barometric damper. When this is set properly it will help with a longer steady burn, with the right sized coal.

This again is a symptom of the small coal. In my opinion, you are making a lot more work for yourself than needed. You are burning less rice coal than nut size because it burns slower. You are also getting less heat.
