Answers:
1) Firebox is firebrick lined (you can see one in the corner of the picture) with the heavy firebrick. I can’t think of the name, put its not the less dense pomice type.
2) The stove has a pretty standard looking secondary chamber with 304 Stainless burner tubes and a Hearthstone thermoceramic baffle. The air to the secondary chamber is controlled via a sliding damper, this allows it to be closed when burning coal. THe baffle and burner tubes are fully removable for replacement (I can’t imagine the tubes will ever go bad, they’re Sched. 40)
3) It has a a 6 inch top flue collar. It could have been made reversible, but since I knew this one would be installed with a top flue, there was no reason to have a hole for the flue in the rear of the stove.
4) The blower is a cop-out. haha. Just a blower, with a rheostat. I know i know, but i haven’t had time to set up the electrical stuff that would turn it on and off based on stove temp. I will get to it, but it isn’t done yet. Right now its just a basic 75 cfm squirrel cage that I picked up broken for $15.
5) The top of the firebox is insulated with kaowool (1/2” thickness).
6) THe shaker grate system is a series of 6 cast iron grates all connected to rotate simultaneously when a lever on the side of the stove is moved. Rather than some stoves, where only parts of the grates move, while others are stationary, this design should help to eliminate dead spots and help all ash fall uniformly. There are two baffles below the grates which help direct the ash into the ash pan, rather than around the sides, where it has to be shoveled out. The shaker grate system is very very beefy, all cast iron and 1/2” steel. It is double supported, ie if welds were to fail somehow, there is a redundant support system anchored to the bottom of the stove that would prevent the grates from dropping, JUST in case.
As I said, the ash pan is 12 x 8 x 12, so this puppy has some ash capacity. Also has a swing up handle so carrying it is easier.
The back of the stove has a 2” air channel which flows up the back and then over the top of the stove through an air grill on the top, kinda like a TLC 2000. THen there is a heat shield that bolts onto four support brackets after that. Given the air flow up the back of the stove and insulating qualities of the firebrick, the backwall temperatures of the stove are very mild. I have the actual steady state one dimensional heat transfer numbers at home, but I’ll try to post them later.
That leve above the door controls the primary air flow. I had originally intended it to enter the rear of the stove and move through a series of baffles before hitting the airwash, but after seeing it in real life and going over the frictional losses due to all the rough bends, it would have been too picky in regards to draft for the airwash to work properly, so I changed the design on the fly.
