This is a Vigas cast nozzle.

That's what it looks like INSTALLED. Mine is still sitting next to the boiler to prove a point that I can wait!

:)
 
round. is yours not?

No, it's a bit oblong.

I'm going to play with my strainer basket a bit more. Mainly wanted to find out how durable this cheap thin kitchen gadget stainless steel is. I was surprised how good it held up in one firing - going to knock some more holes in it for next time. Had no expectations of it lasting any time at all.
 
I'll put some up tonight around 1700 if no one beats me to it.

We got out of work early because of the storm, and the nozzle is too hot to take out now because I had a fire this morning before leaving for work. I will get some pics to you as soon as I can if no one else has. I was going to take the halves out so you could see the secondary inlets in the refractory and the air channels in the nozzle halves.
 
carbon is cooking out big time. idk how long this will last. burns are going well though.

Attached are pics of my metal nozzle cover plates after more than a month and around 3-4 cords of wood.

Coalreaper,

Completely missed this the first time around. In your first pics, you mentioned your Sunday cleaning, and it looks like your refractory is completely bare. Did you just clean everything for the install of your nozzle, or do you always clean it out that well?
 
I just went back over this thread & the pics too.

Coalreaper - you mentioned that your nozzle is round. But in the very first pic you posted, it looks kinda oblong like mine is. A bit longer side to side than back to front. Then later in that series of pics, the shot from underneath with the steel in place, it looks like small gaps on the sides of the nozzle and also oblong. So I'm wondering if our nozzles are indeed the same? I should actually take some measurements next time I have my chamber cleaned out. And I also see you have the same crack I do in the front one. Think Clarkbug has the same also. That's interesting. I still haven't done anything about mine.

I am quite interested in hearing how it's held up - if it's been good, and if they're the same size, I might be interested in one if you get to making more. :)

Maybe with some grating-type pieces laid across the top though. ==c

I rememberl looking at the very boiler that coalreaper now owns. The nozzles are the same shape and I believe they are the same size. I just did a good cleaning on mine tonight and found that my rear section has a crack similar to everyone elses. :( I would also be interested one if it holds up and you are making more.

just for nozzel install. i leave at least 1/4" of ash when i clean out.

its really close to round. not likely to be making more. i can put together a drawing if you want. any machine shop with a lathe should be able to turn it down for yah.
 
update: failure.
started to notice decreased output when charging tanks. the bottom of the liner flared out and cut off the secondary air. started with 1/4" wall and it has lost a lot of material. but no more wear to ceramics.
stainless flavor went in yesterday. will see how that holds up.
