Burning Bitumious Lump Coal in a 1557M Hotblast

Hand fed coal boilers and furnaces using bituminous coal to heat your home or business. Hand fed stoves as the name implies require manual feeding and air adjustments.

You are correct you need to have the grate clear of ashes. The grate will not warp unless you let the ashes build up in the ash pan high enough to restrict the airflow to the grate. The incoming room air is comparatively cold and keeps the grate from getting to hot.

Keep the ash pan empty. The incoming cool combustion air will prevent the grates from warping.

I've read wher people leave the ashpan out and cut the back out of it so u can slide it In and scoop the ashes out. This left more air travel from underneath. Good idea??

A lot of the old stoves had three sided ash pans. I think that just weakens the pan at that end but, it makes it easier to clean out the back of the ash pit.

Will leaving the ash pan out give me more air flow that I need? Down sides to that

I cut the back of my ash pan off so that dumping it makes less of a dust plume. It also makes more room for poking in under the grates. I only have the ash pan installed when I shake the grates and remove ash. This is so that heat radiating down thru the grates can heat the floor of the fire box, which becomes added heat transfer area.

As long as you don't let ash pile up under the grates you shouldn't have a problem with the grates warping. I've never warped a grate in three years. BUT I have broken the nub that the handle slides on to by shaking it too hard.

No this isn't going to solve your draft problem...
I recommend a manometer to help you diagnose your issues..

Maybe I don't have a draft problem. I could want to turn my draft down and use a blower so I can have thermostat control. So u leave u ashpan out so u can get more air to the grate cause ur not getting enuff draft to fire coal. When I took the back plug outta the back of my stove I could feel the air sucking in. I would say my draft is fine

This doesn't tell you anything about draft strength..

Yes you're right.. you may not have a draft problem. You may have an ash problem. If you don't want to get a manometer than don't. You could just continue to guess at what the problem is... :?

I don't know of another way to measure draft pressure...

Wood creates plenty of its own draft since a higher percentage of heat is lost out the chimney. Coal is much more efficient.

No. The only thing firebrick would do on the baffles is retain heat and then radiate it, if the fire went out. I don't see any benefit putting firebricks up there..

Smoke shield? You mean the steel curtain that covers half the load door entry? It helps keep smoke from escaping out into the room.
