I have a large quantity of residual coal slack in the bottom of the

You use it to keep the fire in over night. Lots of slack last thing at
night, shut down the air supply and close the damper. Get up in the
morning open the air supply and damper away she goes...

At least that is my childhood memory from 30+ years ago when we had an
open fire with back boiler.
