I have a simple goal for this project: Be warm in the morning.
I live in a bus and my current stove design gives me about 6 hours with madrone, thermal mass is limited of course. I'd like to burn about 2lbs per hour of pellets minimum and 5 max. My stove is made from a propane tank and a brake drum, I'll attach rough drawings when I have time to get on the real computer. I want to make an insert that simply plops into the stove and allows me to rocket some pellets, I'll use a sleeve on the feed tube to make the burn chamber removable so I retain wood as an option, afterall, I dont live in a bus for convenience, I need freedom. The hopper will be permanently mounted at an offset to keep the heat away from the gate valve.
So here's what I'm looking for input on, 3" square stock for the burn chamber? Sound about right? I am limited to 2" pipe for my intake opening so i dont want to oversize the burn chamber for that, but I do have the option to use secondary air inlets that are exsisting. They are easily plugged because they are threaded.
2" pipe for the feed? From what i'm finding, its prefered to have a feed tube thats slightly smaller than the burn chamber to help prevent flame creep. The brass gate valve as a shutoff is uneccesary but sticks with the steam boiler theme I have going.
The burn grate design. This is a real crap shoot for me so far. In my drawing you can see its wider at the top, i figure this would also help prevent flame creep. I left a gap so as not to block airflow. Should i make it longer and flat like a rocket stove? I figure i can play with this portion pretty easily though.
Obviously a constant electric draw isnt and option, i need every a/h I can get this time of year in Oregon.
