Disposing of Coal

Disposing of Coal

PostBy: chlop On: Wed Sep 11, 2013 5:38 am

Having had at least six outfires in the last two months and not being able to sustain a fire for more than two weeks at a time, I have tried everything that I know of to maintain a fire. I've had three experienced plumbers, a chimney sweep, friends, neighbors, and relatives try to help me, as well. I've can only conclude I have bad coal. Now, I assume I'll be able to maintain a fire when the weather cools off, but if I can't, how/where can I dispose of five tons of coal? If that's the case, the DF520-----only five years old----will have to go.

Have you been watching fire to see if it's exceeding high limit? If it is by the time efm cools down fire will be out.

You need to figure out what is happening. Either the coal goes out from lack of air, or it gets all burned up from lack of feed. It is possible that the coal is the issue, but lets check the simple things first.

Please post your aquastat and timer settings, along with the feed and air setting.

Also, are you burning rice or buck?

As you suggested this problem will probably go away in the winter, if it persists plan B for me would be mixing it with another load.

This is the first year you had trouble? Certainly the coal is suspect then.

just to add...

After getting my EFM install in last fall last year, things were for the most part simple during the winter.

When spring came and temps went up...well this first spring/early summer were nothing short of a PITA

It took setting and trying everything with 100 outfires until I got it right and it would stay for DHW
I would light it and go to work for 5 hours sometimes less and come back to a full ash tray of coal.
Many a time I was pissed and was thinking this wasnt for me.
But then it became so normal procedure to re lite the damn thing.
Then I finally hit the jackpot by setting more teeth on the feed and giving more air.
I got it to 4 teeth, 4.5 air.
I was under the assumption that air didnt need that high since my chimney was high.
Well I was wrong.

Had timer set to 3 min every 25min....trickled that back slowly each day...keeping it lit.
Finally got it to 2min every 50min....and left it there...didnt want to test too much.
Been running about 3 months or more without needing a light (other than a week vacation I shut down and put light bulb in)

My only experience can only help to say that try giving more air and feed (more than you would think) to see if it helps.

If all else fails, buy a couple bags for the DHW, then once heating season comes, almost any coal will burn with heating calls.

I could probably write a book on what I've done with the boiler. In June it was cleaned. A chimney sweep cleaned the chimney. I started having problems in the middle of July, so I made various adjustments. At any one time, I set the aquastat between 150 and 190. I set the feed at 3 or 4 and the draft between 4 and 5. I cleaned out the whole pot after each outfire and looked for any clogged pores. I took out all the coal from the barrel and vacuumed around the worm. Three plumbers made various adjustments. The commonality that all noticed was this----the coal looks like it has a lot of rock. At any rate, the stove seems to be burning too hot. The system skips several cycles; and the fire dies. Oh, I'm burning rice coal, and except during extended days of heat and humidity, the system has worked almost flawlessly. Someone told me I should try to get some "summer" coal, coal that has less rock in it. I just hope the coal I have now-----about five tons---burns well all winter.

The high limit needs to be at 200 for summer operation. Feed setting of 4 should be ok, air at 4 to 4.5. If the boiler gets too hot with the timer at 2 minutes every half hour, reduce the timer to 1.5 minutes every half hour and try it.

Are you using the tankless coil in the boiler? Or do you have it hooked up to an indirect?

I'm a bit afraid of turning it up to 200 as a plumber had it in that range (maybe higher) and the Taco valve he installed had to be replaced. I also remember that the fittings on our hot water faucets started to leak. I have a tankless coil. What's kind of funny is I remember the summer of 2009 when I set the low at about 140 and the high at 160 or so. I guess the type of coal governs a lot.

Nothing more frustrating than this.

Hope you can keep it together to figure this out.

Take Robs advise, because it really helps.
cut down on the timer, try less run, try more time in between cycles.
But the high limit can be controlled, mine doesnt go above 180 now, but I have my limit set to 160-200 or so.
With DHW demand and timer cycles, it stays around 160-170 most of the time.

Just hang in there with more fiddling.
Keep record of coal purchase, temps and settings.

Again, just getting a few bags of another brand, you could put in your barrel and see if that helps for the rest of the summer,
but chances are it is just a matter of settings...... on the air/feed and timer cycles

Give updates if you can, we are all here to help.

FYI if you do decide to get rid of it I'm sure someone will take it, just be clear about the issues you are having.

Rich is right, anyone would take that much free coal (one local ad and you would be swamped with calls). anyways....Did I miss where you purchased the "rocks" load from (might be good info for locals to keep an eye on)?

Doug you have to be careful about jumping to conclusions with stokers, the one year I was delivering coal that was very low ash, If I recall they were testing it at 4 and 5%. That is going to have a lot of BTU's if you can get tit to burn. People with hand fire stoves were ecstatic, lot of good compliments about the best coal they had and probably still the best coal they ever had. People with stokers were complaining becsue thy were having trouble keeping it lit. ;) They all needed to turn up the air and/or reduce the feed rate.

I suspect the things you observed were a coincidence. Many people follow EFM's recommendation and run the high limit at 200 degrees. Try to keep a 50 degree spread between the high and low limit. e.g. 150/200
