Bi-metal thermostat and the ability to burn bit as well as anthracite.

Like you--no lame or anything--I cut a gouge at the bottom of the crack about quarter size & my guy Homer put the shoes on--the biggest problem was all the crap getting in the base of the split--been squirting it with clorox-- in two weeks it 75% closed up by spring he'll be fine--but--his feet are a lot more brittle then my sorrell So I slop on hoof conditioner 30 wgt old motor oil every now & again-- don't tell any of them tree huggers I'm doiung that :lol:

What exactly is the definition of a *base burner*? What makes a base burner a base burner compared to a typical hand fired? Other than the cool design.

Base Burners and Base Heaters are defined by the combustion process inside the stove. The cool design is what makes a Base Burner, a Base Burner. There are three basic types: The mica type like Nortcan has is one. On these the flame path is taken directly from the top of the fire pot and down through a heat exhanging loop under the stove. These stoves are called, "Radiant Heaters," because the body of the stove is mostly mica windows which allow large amounts of direct radiant heat out of the stove into the space being heated. These are probably the most beautiful base burners but in my opinion much more fragile than the other kinds. It is sometimes harder to keep these air tight due to all of the seams and dozens of windows. They are super stoves in the hands of an expert.

The second type is like my Glenwood No 9 Base Heater. It has a totally different design than the mica stove. These are extremely efficient, in fact probably the most efficient coal stoves in existance. On these the fire pot is suspended internally inside the stove. The exhaust gasses go up around the top of the stove barrel and then go DOWN AROUND the firepot between the outer barrel and the firepot itself. Then the gasses are split into two streams and sent to each side of the square base of the stove, then the streams come back together in the back of the base and go up the long back pipe from the base to the exhaust collar. The combustion and radiant functions of the stove are separated to insure the maximum efficiency of each function. The fire stays insulated from heat loss because it is surrounded by super hot exhaust gasses. The coal burns until it is completely consumed and nothing is left but a fine talcum powder like ash. The exhaust gasses have plenty of time after they leave the combustion area to radiate their warmth out into the room. I can run this stove up to 600 degrees and the stack temperature never exceeds 115. In fact it is so good at extracting heat from the fire I have to make sure the draft doesn't die for lack of temperature to maintain an upward draft.

The third type is like my Glenwood No 6 Base Heater. It is similiar to the other Glenwood except that it is designed to be a multi fuel stove whereas stoves like the Glenwood No 9 are strictly for anthracite use only. The exhaust path on these does not stay inside the stove per se, It is taken out through the rear of the stove into a set of exterior tubes which take the gasses down one side of the dual tube to a long U shaped flue under the ash pit and then the gasses go up the other side of the dual tube and then exit the stove. This design is the most all around versatile and easy to use stove I have ever had. The prismatic grate system is competely contained inside the stove and all the dust from shaking is kept in the stove. It is also extremely efficient and it produces large amounts of heat for a fraction of the coal that a similiar direct draft stove would consume. I hope this clears up your questions

Could you post illustrations of the gas flows for each design. For someone not familiar with anything other than a barrel stove it's difficult to understand.

Ideally someone that has Google Sketchup would draw the illustrations.

Yanche, I did a hand sketch some time back and posted it here. It would take me longer to find it than just re-post it. Not a beautiful drawing, but I think you get the idea from it. I've drawn out the Glenwood #6 only.

Thanks for the pic. Does anyone have a pic or drawing of this suspended fire pot it seems like an interesting idea.

Does the base of these stoves run hotter than a regular stove? In all the old pictures and advertisements I see the stoves directly on a wood floor. Also where is the best place to buy new prismatic grates for my Andes? I think one is slightly warped.

This is a picture of an unrestored #14 Art Stewart base heater with the suspended fire pot. Note the cast iron grill at the top of the fire pot. This lets the hot exhaust gas jacket the fire pot on the way down to the heat chamber surrounding the ash pit. Then the exhaust goes up the long back pipe and out the flue.

Yes, the base runs hotter than on a regular stove. When I start mine up, I run in "direct draft" until the fire gets going well. Also, when I'm running wood, I usually run in "direct draft". By "direct draft", I mean the back valve is set so the smoke does not circulate through the base. In the shoulder seasons, fall and spring - well mostly fall for me, I'll run wood. I don't usually get to where I'll be running in base burner mode. The stove will throw out a lot of heat, but once I do switch over to base burner mode - usually after I get the coal fire running well - I can sit in the chair near the stove and feel the heat coming out of the base. My tools to work with the fire will be quite warm when I pick them up if I leave them under the stove. Something I often do just for space saving.

I've never had mine directly on a wood floor. Years ago, we used to have a sheet metal piece that went under all our stoves, stuck out around it also. I used to think it was for catching any sparks or embers that fell out of the stove, but now I think it also worked as a heat shield for under the stove. Now, I run the stove on top of a tile base, like the look better and also think it works well.
