Part 5 - Insulation

We are going to be insulating like crazy here. 2" of insulation on the main body of the roasting chamber. Kaowool and a rigid insulation board if needed. This is the stuff they insulate furnaces with. You can melt iron with 15 amps and sufficient insulation. The front and back will have at least an inch plus a layer or two of hardibacker. An Alchemist's furnace we are talking here. :@ And so I don't forget it, I want to seal every seam that could leak heat or smoke with aluminum tape. We'll see if we need a gasket along the metal to metal joint of the roasting body and the base. I think if we take care with flat, flush construction no seal should be needed. We are already recirculating our heated air and only ejecting some when we WANT to. The name of the game here is energy conservation!!!

1 1/2 Pounder Posts: 690 Joined: October 27, 2005	Yep, and it would never corrode. I do like the color.... Say, aren't those spots of PURPLE on the side?

1/2 Pounder Posts: 287 Joined: November 02, 2005	Indeed, on both counts. They even do custom work. I fear it may be a little outside the budget thought. I always wondered about a boiler and PF and basket in an espresso machine made with silcosteel. Oh, and I made a discovery today with my Zen II. I have now installed the halogen light you purchased. With the new MASSIVE illumination, I could see where and how I was getting as smoke as I was. It was literally forming at the gaps in the front where air was coming in. I could see it form. The mixture of fresh oxygen with the roasting environment produced smoke that immediately wanted to make a departure. I sealed up the front seams with some aluminum tape and my smoke drop 80% I would estimate. I need to hack the halogen fixture a bit and see if it will work as an afterburner. That light is damn hot.
