A

That's okay, you do kind of whatever.

A

So what you're gonna do here, is you have your coils? So this is a gasifier well.

A

For a pelletized pelletized biomass burner here, yes,.

A

Because it's it's a when you have a stationary power supply. You do things differently, because you have a lot of room, so you have a big smokestack, so you have a smokestack 20 feet tall and the smoke comes out the bottom and it goes up the smokestack because this smokes gonna be, you know, 400 degrees. Maybe you can get it down to 300 degrees, but it's hard to get much below 400 degrees.

A

So there's several ways of doing it. One way is you put your pellet burner.

A

So you have a fan, you always burn your your pellets in a cast-iron pot and the better ones I know have little holes drilled in them.

A

So this is your plenum. The air blows in here blows in through the little holes swirls around in the pop. Your flame comes up here.

A

Your flame comes up here goes down through. Here goes up the smoke standard. Now you can take this and put right on top. If you want to, and the flame comes out, you know, then the flame comes out and goes down, and it takes a little bit when you're trying to make this corner with your heat. To get it started. It takes a little bit. It's gonna smoke a little bit until you get your hot air in here and then it'll draw soon.

A

As you get hot air in here, then you get plenty of draught and plenty of draw. So your smokestack Poon's is always cheaper than a fan, but it just takes a little bit to get. It started.

A

How would you put this right on top here, so just close that off and draw the draw that there? This is the this could be the secret right here.

A

You have to have a fan to get it started and after that boohoo, so you have your crucible.

A

We have a corn burner, which is the same as a pellet burner over here, so you can look at it and it works kind of good enough.

A

So you have your flame here, but all you do.

A

Just kind of round those corners see your flame comes up here, and it goes down here.

A

So that's that's rather counterintuitive that the flame is on top right.

A

You need to put the flame on top, you can put it right beside and it doesn't really matter if you have a lot of you put it on top it's kind of up in the air a little bit, which is even it doesn't really matter where you put it. You got to have your your flame is a separate unit. It's a combustion chamber, and it just is a box that flame and hot gas comes out, so it doesn't matter where it is.

A

As long as you have an insulated pipe to pipe it where you want what's the thinnest, can you make a thin pipe like six inches across? That's the burner chamber.

A

I would have to look at I forgot what our what's our BTUs on that corn burner Terry, you remember, look go look at. It was a 250,000.

A

Fine 50,000 see that's only a gallon a half an hour so but they'll get you a five horsepower pretty much. Okay, you go! That's how you, okay, that's how you make up.
