Burning house coal

[Annpan]

I have been told to only burn smokeless fuel in my 'multi-fuel' burner... but... I am unable to get any wood delivered until the weekend, and I have half a bunker (couple of bags worth) of house coal sitting in the garden...

What's the problem with burning regular coal - I don't live in a smoke control zone and our chimney is lined.

What's the worst that can happen?

Who told you that? and why?

Can't think of anything. But then I don't own a fire, coal or otherwise.

If you can burn wood in it then the only thing that might be awkward is getting the clinkers out of the grate - specially if it's one of those that swivel, wood and smokeless both go to dust/ash but coal will leave cokey clinkers behind

The glass may smoke up and the clinkers can be re-burnt just as they used in Victorian times

I don't think a couple of bags will do any harm A. Might cause problems with sooting up if you burnt it continually but even that's not the end of the world.

good luck, Paul
