Hi Bellzy and welcome,
so long as the flue is large enough I see no reason why not, but, and some would disagree, line it if at all possible, even if the present chimney is in good condition. Have a good look at your Rayburn, it may actually be a solid fuel one that has been converted to oil anyway, as many were and it is possible that you may be able to convert it back.
I'm sure that someone who knows more will be along shortly

Cheers, Paul
