Amazing!! AHS 130 Won't go Out After Shutdown

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

This past Spring I had to put a recycle timer on my boiler to keep it going. If I didn't have a call for hot water or heat it would go out in a matter of hours. Now that I want to clean it for the winter season it won't go out!!!! I shut it down on Sunday night and it is still going strong. I could flip the switch and be back in business immediately! I know it has to do with draft but I am only reading .0 to .01 at best. I don't want to empty the hopper for fear of exhaust gases but how else can I get it to go out? Amazing!

That is a compact burn area, and the only area to supply air is from underneath. You must have good coal, an adequate draft and the perfect situation to support combustion. Lots of us have been saying for years that the fires will burn for several days with the controls turned off. If you need it to go out, either burn the hopper down and remove any extra coal, or wait a couple weeks for the burn to slowly quit. You know I am kidding, but if the fire is that low, you can ventilate and dismantle the blower assembly and have it out, on the floor in about 15 minutes. When we do service work, seldom do we have the luxury of the boiler being dead cold. Only do what you are comfortable with, no dead hero's needed. :idea:
"Political correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a 'piece of human solid waste' by the clean end." More true today....

I knew that the draft situation would be different this time of year versus the Spring, I just didn't realize it would be this different. Also you are correct WN the coal I am burning this year is so much better then the stuff in the past. I fired it back up for today as my family is tired of taking luke warm showers and being cold off of the oil burner. Tomorrow through Sunday will warm up, I am hoping the conditions will change enough for the boiler to die down then and I can clean it out by weekends end. We shall see. No dead hero's here!!!

See if this idea can work for you...

Disable the fan circuit and then force the grate circuit On to dump all the hot coals into the ash bucket. The hot coals will extinguish themself after being dumped/disturbed.
DO NOT ATTEMPT IF NOT KNOWLEDGEABLE WITH ELECTRICAL SAFETY

I've never attempted to turn mine off in order to force/extingusih the fire, but I do know that it takes mine 20 to 21 days to go from a full hopper to empty (and fire out) when I shut it down at the end of summer for its annual cleaning. I plan for my target clean down date well in advance accordingly.

Wow 21 days on a hopper. With my heat load in winter I can go through a hopper in two days and another day for the fire to go out. If the temps are in the 50s I can get three days out of the hopper and two days from the burn pot.

So 21 days and how many hours? probably depends on the tidal effects of Jupiter :lol:

I'm always impressed with your well kept statistical information partner 8-) :)

20 to 21 days is for summer running to provide DHW only. In the depths of the winter I'm topping off the hopper every 2 days. Currently topping off every 3 to 4 days.

Why is this a problem? I very rarely let my EFM go out for a quick cleaning, but I do make sure the area is well ventilated when I am working on it.

Edit: If you need the fire to be out, open the chimney clean-out door before you go to bed. The fire should be very sleepy by morning, and maybe out entirely.

We're talking about an AHS here...remember the air is coming in the view port over the top of fire...not necessarily up through the bed of hot coals. The hot coals are setting on 5-6" bed of insulating ash in a 11" dia. tube and probably standing ~11" in height...when it's go'in good it doesn't give up till it's all gone. ;)

My cleanings are by no means quick (3 to 4 hours), I disassemble most of it and that included the stack.. I don't really want flue gases filling the basement while I am working, the wife tends to get cranky!!
