Sulfur Smell

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Either you aren't burning hot enough or the coal simply has a high sulfur content. I've been burning coal for most of 10 years now and sometimes it's very bad, sometimes not at all. I always get it from the same guy but I have no idea where he gets it.

with this crappy HEAVY weather we've been having here--I've been having some sulpher smell outside--it's bad tonight--but the weather is REAL heavy--I don't know what you've got weather wise in NH---I always keep my manual damper 2/3 closed---no fumes inside

MPD should be left open for several minutes or more after adding a new charge of coal. I don't think its necessary to leave it open for an hour or so.

Leave the MPD open. If the smell goes away, lose the MPD. If it doesn't, try loading your coal like last year.

As OP said,if you're getting some inside--open the manual damper & leave it till this cold sets in :) then shut it some

By loading coal in a large batch it takes time to get hot enough to burn the gasses, which leads to the smell. You were doing the right thing in loading in layers. When it is colder you can load in larger amounts since the stove will be running hotter. Many will leave the ash door open until blue flames appear before closing the ash door. The major advantage of a hopper in a stove is that the fresh coal will be very hot and near ignition temperature so will ignite gasses quickly.

I would open the MPD and then I would shake the stove down. Next, I would add the coal in layers like you did last year. Give it a little time to catch good and you see the blue ladies and you know that the gases are being burned off. Now when you have a good fire going you can cut back on the MPD about 3/4 closed and see if there is a difference. Some stoves seem to get choked out when you fill them up quickly in one shot. You will have to experiment with the timing when to close your MPD 3/4' s of the way.

if you're getting sulfur smell in the house consider that an indicator of a problem, not THE problem. the loading/sulfur content of the coal isn't the issue, the flue gasses entering the home are, be thankful you can smell it. lose the MPD

I too am not a fan of MPD's in pipe when burning coal. Barometric damper I can see. But not a manual pipe damper, in a modern air tight coal stove.
