Question About Unburned Coal When Using Coal and Wood

So after the advice you guys gave I have been able to use the coal to pretty decent effect for night burns. I’ve been getting about 12 hours out of the coal. I have found that with the coal loaded a little above half way up the fire bricks has had the best effect, any more then that tends to choke out the fire. Probably with a larger size coal I wouldn’t have this problem. My question is in the mornings when I go to switch back to wood, I feel like I have a lot of burned coal that hasn’t turned to ash and has to be shoveled out of the firebox, js this normAl? I will try to add a picture for reference.

Also is there ever a sulpher smell to anthracite? I’m wondering if there might be some bit mixed in, as I get that smell hanging outside faintly when it burns sometimes.

With Anth. you'll get a lil sulpher smell if atmospheric --cool word-- conditions are right--HEAVY! Is your stove a combo--wood & coal? You're using nut?

Yes from what I understand I made a bad purchase if I plan on switching to all coal. Luckily I have a lot of access to wood and mainly want the coal for long burns when I’m not around for right now. It is nut size.

I would not cleanout the fire box, but shake down well and start the wood fire. Any coal left will burn.

That is what I did today and the picture is still what was left unburned.

Don't lite a coal fire unless your going to burn it for a long time, it's not like wood and will not burn up in full like wood.. I won't burn coal unless it's for a week at least...

That's okay, shake it again and continue to build your wood fire on top, unless those are clinkers/slate and you have lousy coal.

As a matter of fact, that stove could be modified to burn coal just fine.

+1, but your going to need a good hot bed of wood coals to get the coal going again, but it will work..

There is some learning curve with running anthy in these multi fuel units. As long as you have decent draft, ashes cleared properly, a healthy burning bed left after shake down and most importantly - have blocked any places where primary air can bypass the grates - you can load to the gills and it'll go.

There doesn’t seem to be any other place for secondary air to go in. It burns great when the ash pan is open and goes down to a simmer unless I have the damper open most of the way.

That looks like a coal meatloaf... lol, pile it on until you cant anymore, then keep it under control with air. make sure you can control the air so it don't run away. I know as a newbie myself it's hard to wrap your head around putting in all the coal you can, over time you will understand this..

That looks good to me, other than that it's a little shallow. There shouldn't be any problem loading more coal on top of that. Leave the ash door open till the fresh load is burning good, just don't leave it unattended while it's open or forget about it.

I would block the front and rear liners so primary air can't bypass the grates. That's just what I would do lol.
