Just open the MPD, your fire is hot, so no need to 'rev it up' with extra combustion air. Just load the new coal in a hurry, it will smoke when added to the hot fire..

yes I added 4 football sized pieces to the top of the bed, it burnt ok overnight but the 4 pieces welded themselves together and stayed above the coal bed as it settled over night it did ok, so im not complaining right now :) thanks

I'm surprised pieces that large fused.. That's one of the 'issues' with some Bit coals. A firebox full of nut sized bit coal with a high swelling index will swell, bridge over the burning fire, and the fire can burn out below the thick bridge of coal..

What I'd do when I hand fed Bit to my 'Big Bertha' boiler,, I'd load it up, close the door in a hurry,, and return in about an hour or two,, and use a heavy poker to break up and collapse the bridged coal..

Bit makes lots of heat, it just takes different proceedures to burn it well.. and to confuse things, Bit coal from one mine will act one way, the coal from a mine somewhere else will have different swelling index, volitlle content, ash content, etc.
