^Nope and don't plan on installing one. I have no desire to control the rate of burn. Hot, fast and clean is all I am interested in.
I suspect the flue might be a bit on the large size, however I played around with closing off the flue last night and it made no real difference to the smoke production.
Whatever I do, the smoke is either there, or there a bit more.

Lewis, I' guessin you leave the burner to get really hot? I've got a wood burner in my shed (ex gas bottle), it puts out heaps of smoke until it is really hot. 15-20mins sometimes.

Same here, but fires need to get up to heat before they burn clean.
Building fires can be a bit of an art, I do think that keeping such a small fire burning at full pelt will be laborious. The best solution would be a good controllable air intake, that way you can get it hot and keep it simmering away.

hope it's going to be silver....... Sadly, i saw this thread a bit late - i've just ripped out my wood burner this week, which has a built in water jacket. You could have had it, as it's past its best and only going to be weighed in. Not as rewarding as building one anyway, i guess! Cheers, Joe

Joe - thanks for the offer, might be tempted, although a long way from hereford.
I have been tinkering away, but not had an opportunity to post any updates. I will do at the weekend. I am currently a few hundred miles from home on work business, so it has been put on the back burner for a while.. (badum-tish, I thank you!).

been having a think about this, is the smokey burn due to a lack of draft with the short chimney?

Ive been thinking about converting mine to a drip feed oil burner. Looking at some of the builds on youtube, if the design is right, they burn cleanly and no messing trying to keep piles of wood dry. And the fact that there are hundreds of litres of old oil at work waiting to be liberated

And the fact that there are hundreds of litres of old oil at work waiting to be liberated Once they are started and hot waste oil burners are great, don't think they do much for air quality though;) and i think there are issues with using them in commercial premises for that reason - although that wouldn't matter at home. If you built one with a back boiler you could heat the house too

Used Mickeys Chimnea over the weekend to burn a load of green and dry pine rubbish etc..... smokey as hell till it warmed up, then drew like a train, clean, fast hot burning.

Thanks for the comments guys.
I have been playing around with the air intakes, and also managed to score (for free (winning!)) a 150 mm wide 3m long length of steel ductwork to act as the flue.
I fired it up and it went mad! It got really really hot, bottle glowed red hot.
Pics tomorrow.

Hi, I'm new here, but sooo glad to have found you and your brilliant experiment, just the inspiration I needed to find! And! at the right time! Can't wait to read more. PS, great welding!

Right, evening all. Sorry for the delay in updates, but I have been all over the UK on site visits recently, so evenings have been very busy. So here are a few pictures of the test burn I did the other day, the one that worked! Here is the burner without the flue. You can see just heat haze, NO smoke. This is just what I was after Here you can see the 150 mm steel ducting flue Right, here are the modifications that I made. I added a secondary air intake feeding air into the back of the burner and up behind the baffle. I tweeked the baffle, and added a flair to the front edge to help hold the fire below the baffle to mix with the extra air. It seems to do the job. I then started to double weld everything (inside and out) that I could I then set about welding the top on Cleaned up I just need to clean all the old burnt paint off, and give it a few coats of high temp paint to help slow the rusting down once bathed in water. I just hope it is water tight!!! Lewis

Brilliant progress. Loving the fag lighter welded into the baffle! Was that intentional?

It is not a fag lighter. It is a scrap of metal that I used to seal up a hole in the baffle (old sit on lawn mower seat base).

^ Fair does. It really did look like a melted fag lighter which would have been pretty epic.

Right. a bit more progress. I sanded the old paint off and gave it a coat of BBQ high temp paint. I layed about 10 coats on the weld joints to help ensure that any pin pricks are blocked (I really do hope it holds water!). I then set about cutting more out of the old air tank to enable me to slide the burner section into place. Cut out of the rear air intake It has spread a lot now that I have cut the sides, so I will need to ratchet strap it back into a more round shape before welding the front back on. Starting to weld the burner into the tank Tacking the rear strip back into place. More pics soon. Lewis

I am really enjoying this build Lewis.
Your welds should hold back pretty much everything you throw at the boiler.
Looking forward to completion as well, although it means one has to find anothe thing to build or read.

Nice work, I'm getting in to this now. Make sure you take proper temp measurements when It's up and running.
