[TheForge] coal stove

[Peter Fels & Phoebe Palmer]

Kim; There are a bunch of variables in stove efficiency.
Like a forge or a carburetor, the air mixture is critical as is the velocity and temperature of the incoming air.
The refractory qualities of the fire box matter a lot as does the efficiency of the fuel/air interface.
Adjustability of the air intakes and their shape and placement matter , as does the stack flow and velocity, and, of course, the ratios between them. The object is a hot, clean fire.
Once all that is tuned in, the stove has to extract the heat for you without ruining the draft.
And stuff like that.
My vague recollection is that some of those stoves were designed for wood, others for coal and some tried to compromise awkwardly.
A strong grounding in fluid dynamics would be helpful in design.
Surprisingly subtle things have a considerable effect.
I welded up a bunch of one-off stoves and fireplaces over the years, and had to change some of them
a number of times before they worked passably.
Now you have been foolish enough to read ramblings about fireplaces and stoves by an old guy
who lives in temperate, central, coastal California. 
We don't know what cold is.

Flu size is the same. It is a typical barrel style parlor stove . The
grate is about 16"and stands about 4' high.has a large draft opening
in the ash door and constant draft opening in the upper loading door.
The grate surface is 1/4 to 1/3 of my other stove. It also has a large
thermal mass around the upper 2/3ds of the stove.
