can't get enough heat out of VF3000

Gonna Chime in on this. I have a Magnum stoker and had the exact problem Hillside is having. Just a lazy fire and no heat output. Only variable was I put newly picked up coal in my stove. Same dealer as always just bought it couple months later. Once that coal got onto the fire it just killed it. I checked everything, then checked the coal. It was just COVERED in fines. So my quick solution was to put a drying rack over my ash pan and sift all the fines off it, or as much as I could.It was amazing how much came off the coal. Once that "clean" coal was feed thru it was burning like it normally does. All these symptoms sound all too similiar. Please give that a look...

OK, I checked the ash compartment and it was pretty clear as I expected it to be. So I emptied the bin and put in 2 bags of Centralia brand coal from Wilkes Barrie PA (says deep mined) but not really sure where or who the actual mine is but there is a big difference in the flame... now what to do with 6 ton of low performance coal?

The coal does seem to create more fines (in the little removable tray and under the grate inserts) than what I remember from before. This is the first coal I've bought from Sherman Coal Co. , Elysburg PA, Do you think the problem is the coal? or do I need to look for something else? It's really driving me nuts.


I'm assuming you previously had good results with this boiler in your home? There is a question I asked hillside a couple times that I don't believe he ever answered. In the ash compartment, there is a metal door that slides down over the area where the flue pipe exits the bottom of the boiler. Have you removed that and cleaned out the flyash behind it?

Hillside,
Where in PA are you?
I travel across PA for working, so if you are close I'll be more than happy to stop by and see if I could help.
I have a VF3000 running for the past 4 years non stop 365 days and I have to turn it down because it overheats
often.
Like everybody is saying, something is just not right.
I'm heating 2 1000 sq. ft. floors, plus I have a water heater coil installed for my domestic water, and my temps drop down to maybe 150.
I have the aquastat set at about 165 most of the time.
I live in Poconos PA, so it gets cold here, house is a new construction, but very crappy job, quarter inch space between playwoods.
VF3000 is more than enough for me. When I first started burning coal people helped me (coalkirk) late a night tshooting my issues ( I had overheating issues).
Now I feel is my time to help fellow coal burned.

Bryan,

You can always mix it in with some new better coal. Just vary the ratio depending on outside temps.

sounds like you need a wash plant to get rid of those fines off the coal....i bet the Hoffman boys in Alaska have one they could sell you cheap....just don't depend on them to get it to you!! :D

Centralia is pretty good coal. I had some stove coal from them for my hand and it was excellent. White/green woven bag.

Now we're talkin'. Another set of eyes is always a good idea, especially if they belong to someone that runs the same boiler.

Sorry I haven't gotten back to reply. The temps here in the area have been in the 30's so I am not sure if I have made improvements or not as the boiler kept up at those temps before. At least for the time being it is getting to temp and shutting down now. When the temps drop I will let everyone know how it is working.. I did everything everyone suggested. I really appreciate the replies and imformation...

could a bad aquastat or thermostat control cause low fire... Sorry if it was mention still haven't had my morning coffee... It seems Hillside has tried draft suggestions, but not much mention on electric part.
