What are the temps on the stack and sides? Also how much ash on the end of the grate, assuming it is plate burner and not a pot. Brand and model?

at full throttle you are going to have about an inch of ash at the end of the grate.
how big is the space that you are heating? any insulation in your house?
is your stove in a basement?
i heated a 20x30 room with r11 ceiling insulation and block walls with r3 foam sheets and paneling on half the room with my alaska. when it got really cold i had to run the stove wide open to keep it in the mid 60's i had a box fan behind the stove to help move the heat around more.
insulation and thermal break are important. seal up the drafts the best you can.
here at the homestead i installed a 85,000 btu reading coal stove when i moved home. i have it in the basement so i'm heating 3 floors, about 2600 square foot total.
the stove runs wide open when the temps are below 35 degrees. i have the downstairs thermostat for the coal stove set at 73 degrees and the oil furnace set at 69 degrees. i had some 3/8" foam installed under the new siding and just the added r2 and the thermal break have made the house more comfortable.

Do you mean a stoker stove? 85,000 is pretty small for a coal furnace.
If its the 85k btu number you are trying to verify I think you'd have to measure the weight of the coal that is fed through the stove along with the run time of the stoker. That gets you how many lbs / hr are being burned up by the stove. Then calculate the btu's / hour by using the btu's per lb of coal . You should probably figure out the unburned coal from the ash by weighing the ash and using an ideal ~14% ash ratio and subtracting any percentage above that. Then subtract out the stove inefficiency percentage and you'll get a nice WAG at it!!
or just ask Isayre to come up with a spreadsheet!!!
