I bought two meters. They will be up to the grid at both ends. For a given temperature of the grill.
I am studying a very simple system. This diverted flow of smoke towards the other end of the barrel. Then there will be smoke flow from both ends (as in reverse sistem)
Involves the incorporation of a metal plate, forming a tunnel and divert less smoke pipe to the other end of the barrel. This will have the advantage of generating more heat inside the enclosure.
Reverse flow is cool. Really, the chimney out the side (just above grate) and up, on the opposite side, is about the same (see pic of smoker I posted). Reverse flow takes more work, but yes, it pulls it back straight across the grate.
What is that metal on the lid? Did you know galvanized metal on a smoker can cause heavy metal poisoning (zinc poisoning)? Usually you avoid all galvanized metals.
Then put pictures, for you opinion, if it is desirable combined reverse flow.
Indeed it is galvanized. But this outside. So do not think that entails danger. The function of this sheet is to give strength to the door and cover the separation between the door and the barrel.
I ignored the dangers of zinc, but will not have contact with high temperature or the interior.
Before I did reverse flow I would test your smoker. I'm already worried about bringing the chamber up to temp, and reverse flow means your chamber will be even cooler since there is a plate at the bottom and the smoke doesn't enter the chamber until it reaches the other side. Then, your chimney/damper on the same side as the firebox pulls it across. But you really need good airflow for this to work and you have a small opening. I think this would kill your smoker. You need to put a damper on your firebox. I don't see one.
Oh okay I thought that was the coal tray. It can work as a damper as long as you can control the air well and almost close it completely, same for the damper on the top of the chimney (usually a cap works that you can slide). Where do you put the wood/coal in?
The gate is too small for the coal. It became a function of controlling the flow of air. The closure is almost airtight, so it has to work. Due to the cylindrical form, was very complex system make another gate.
Try missing photos with more zoom, to be better appreciated.
The wood / coal anger in a basket in the firebox. I have not yet built.
In reality, the day is over. I put it to work at maximum temperature to burn inside for more than 3 hours. With all the locks open.
Reached a maximum of 210 º C (410 º F). Then exploiting the temperature of an oven, I put a tray in the smoker with meat, potatoes, tomatoes, peppers, onions, scallions, olive broth, salt and beer.
THP thank you very much! Yes, lots of smoke escapes. I am thinking how to put some material that seals the exhaust smoke. Try using high temperature silicone. I think it is safe at these temperatures
I made a basket for charcoal. Be tested for operation. Then build something better
Apple wood chips, soaked
107ºC (225ºF) for 4 huors
The pork ribs
A fish, some chorizos and morcilla
Being the first time I reach the goal. There is much to improve and discover.
Tomorrow will do an update and I'll add more a pipe interconnecting both drums. I had difficulty maintaining temperature and at times down to 80/90ºC (180/200ºF)
Way to break it in right. I always found it tough maintaining that sweet spot @ 225 till I used a total separate fire box for making coal then adding as needed to the attached fire box. Was getting too many flare ups with adding straight wood to fire box, if it needed a bump up I'd add small dry pieces directly. Now I have gone the electric route, less stressful and far easier to maintain temps.
