Rayburn automated temperature control?

Yep I'm with Bill. The only thing you might want to change is the flue damper and the flue chamber door (diluter) if the wind really drops or really kicks up, but on an hour by hour basis this is less of an issue. Using anthracite I'd have no problems maintaining 180-200 degrees.
The only thing that could impact it is if I ran a bath which would then deliver cooler water to the back boiler which could take a little heat away from the oven but not hugely....

I assumed on here we would only be considering wood, and hence a more variable burning regime.

Im actually wanting to burn a mix of sawdust and glycerol - so a very homogenous product.

(if anyone wants to mention acrolein - please remember that acrolein is highly flamable and take that into account in any comments)

One thing im concerned about however, is that, as it burns (and must be burnt) so hot, i dont yet know if that will make the oven much hotter than is good for cooking.

Hopefully your fire bricks would help a bit with that. Is it plumbed in or just a stand alone? If plumbed then the water can take any excess heat if that is a concern?

Its neither yet...

The house we are trying to purchase has a suitable space for one, and my partner is a keen cook, and very much liked the oil fired aga where we were staying previously.

I have plenty of glycerol from biodiesel production, and, with care, it makes a good fuel, so, adding it all up (not to mention where we are trying to go has no central heating at present)

So, im just plotting at the moment!

I've been lucky enough to live with Aga and Rayburn most of my life and for cooking they can't be beat but solid fuel Rayburns inherently have  crude control. How about you convert the rayburn to burn Glycerol direct with no sawdust, this might give you a burner that could be controlled by conventional boiler technology.

I confess I know now't about glycerol but these people claim to have a Patent Pending on glycerol burner. So if it can be done I'm sure some one here can copy/bodge it!

My fear, from an insurance point of view, is that a servo opening and closing the exiting / original vent is one thing, whilst a complete modified burner unit, running on a fuel that most people have never heard of, is entirely another : (

I think most people have thier crazy non-complient heating systems outside of the home, where, if the worst happens, and they burn down, its no big deal.

Sadly, i think a servo controlling the original equipemnt would probably be about as far as i would want to go : (
