Also just noticed coals2u are doing the olive waste briquettes (Homefire olive briquettes) for £4 for 10kg rather than the previous £6. Worth a try I think. They do free delivery if order is over £30. Seems pretty good.

They say it lasts twice as long as wood but there are different types of wood. I imagine they are comparing with commercial softwood logs rather than nicely seasoned Hawthorn for example which burns for ages.

On the Aga /rayburn thingy I burn mainly small anthracite..worked out how to keep it alight all night...I sleeps on the sofa and checks it regularly. I like the small anthracite but it don't work in the multifuel. On the multifuel in the lounge burn smokeless/wood/heat logs/wod.coal mix thingys...gets lovely and warm..just dragged half a tree though swampy area, up a bank, over fence up the garden where it lies waiting waiting for me to saw up. Its hard work foraging. I do buy logs as I need them cos theres to many in a load for me to move.

On the rayburn house coal blocks the flue in a week!! smokeless about 3 weeks and anthracite [good quality] just over a month so you pay your money and takes your pick Sounds like you could do with a bit more 'top air' and an insulated flue. Chimney goo is just unburned volatiles condensing inside the flue. (I was a child pyromaniac...)

I must say I never had problems with the flue on my Rayburn. The flue is 3' internal (un-insulated) and 6' external double skinned.
This is a homemade contraption which consists of a thick walled steel pipe welded to the deck with an ordinary enameled flue inside it, the gap, rockwool filled and the top joint capped with high temperature silicon. The flue is next to an area of deck that you walk along so it was essential that it never got hot enough to actually burn someone.
When I was burning house coal mixed with var. types of manufactured fuel, I had to clean the flue every few weeks (Rattling a chain down it) but when I was burning anthracite it never seemed to need doing, although although it used to get the same treatment.

Allowing more top air until the volatiles burn off should help. I guess if a fresh load of coal is smoking when added it might help to burn some dry kindling on top with extra top air, to burn the smoke as it comes off. Soot is just unburned carbon, just needs the right air (and heat) to burn in the stove before reaching the flue. www.google.co.uk/search?q=burning+coal+volatiles+"top+air" www.google.co.uk/search?q=bituminous+coal+"top+air" Maybe Rayburns don't have good enough controls to allow this? Haven't used one myself.

I think it might be because you are using the temperature of the fire to control the temperature of the oven as well, you don't always want it going like the clappers if you are doing a casserole

The rayburn is essentially a cooker and water heater, so the flue gases do have a long complicated route to the flue which is the issue. You dont have any top air controls which would be handy if it got rid of soot. I burn hot morning and night to clean out deposits but the anthracite from abroad is shit!! and it is full of it as well! so it clinkers up to death. Carl my coalman wont sell it me as its so bad, so I burn blue flame which is anthracite petcoke mix, burns to a powder, doesnt last as long as anthracite but is a lot cheaper so works out the same

My ideal would be something squirrel size but with an oven. I do slow cook and re-heat food on top, but the flue is a bit in the way.
Anthracite is good but needs too much air, I found it wants something between fully open control and lower door very slightly open or it either burns too hot or slowly goes out. After 100kg of that I'm trying Supertherm. Which is smelly and not as hot but far easier to control with both doors shut as they should be. I can get it to stay in overnight every time.

Maybe open it up for a while before refuelling to get a nice chimney draft going (and burn some soot), might even help if the existing fuel can be pushed back a bit so the newly added stuff doesn't smother it. Could even try a mix of fuels to try and get the best of both so to speak. Plenty of aga discussion out there so a traw of t'web might turn up some ideas: www.google.co.uk/search?q=rayburn+soot+anthracite

I've got a fairly small (firebox smaller than a squirrel) dutch cooking stove. No oven but the top is extra big And has 3 cooking plates on it.
Can't deal with anthracite at all!!
Homefire or brazier is best will stay in for about 12-14 hours.
I have seen very nice French cooking stoves on eBay now and then which look like half of a rayburn Nice.
I had a rayburn MF for 4 winters about 10 years ago on a narrow boat. Nice but not really sure I would want one again. Its tempting but the amount of fuel and ash going in and out is quite considerable.
Also takes a long while to warm a boat up if you have been away (a coal/wood burning version I mean).

The fire is normally burning well anyway when I refuel, I just think that it is the design of the rayburn with its long and large surface are to the flue have a look on line and you will get my drift because that is what the smoke does gently drift!

Shows how much I know about Rayburns - zilch. So I'll shut up.
