This is my first 8 inch batch Rocket Stove.
The built was base on the sketchup file that Peter shared. I used only one barel and the riser is shorter(45 inch high) than the original design. The gap between the top of the barrel and the top of the riser is 12 inchs. For the riser, I use high temperature insulated bricks ( suppose to support temperature high as 2600 deg F.) I replace the window by a refractory slab and to some cutting with a gap of 1/2 inch to allow the p-channel sealed with ceramic wool. A ceramic plate was used to support the p-channel on the firebox. Low duty refactory bricks was use to build the bottom and the side of firebox. The back of the firebox was built with super duty bricks. The firebox was wrap around with perlite and clay slip and finaly cover with old clay bricks. The rear end was shape like a dome (built with cob) to receive the flue gaz from the barrel and redirected to the bench of the first rocket stove (35 feet pipe inside the bench).
I use a sheet of metal just over the barrel as firewall suspend from ceilling. I will double the surface of firewall to get ceiling at lower temperature.
The finish of the bench is a 2 coat lime plaster (quicklime slacked).
First fire experience
We forgot to prime the cheminey and smoke come out from the p-channel... After priming the chimney with a propane torch for 10 minutes, just enough to heat the cheminey, everything goes fine!
We were very impressed how the barrel irradiate the heat!
Second fire experience
The next day, the bench was enough hot to not need to prime the cheminey. Put some wood and kindling into the firebox. After lightening up, 15 minutes later, gaz inside the barrel was 1600 deg F!
Very Very happy! :-)
Thanks you Peter to share this very good design and all of you that make this possible!
