Last run in HK-J series
Condar series
Maple, 18% moisture, 78.0 lbs
5 round pieces of maple, with 3 pieces of white birch on top, 2 on bottom, 10pieces
Warm heater (162F firebox temp)
cold fuel
Side ignition, cold kindling, 4.0 lbs
Similar to run HK-J29, 1/2 lb more kindling, larger load.
Nice clean start, then fire overamped at 27 minutes, creating large opacity spike for 10 minutes.
Dark grey smoke from stack. However, PM number still reasonably low, indicating that this was pure soot with no tar, as would be expected at this stage in the burn.
This is an interesting demonstration of the high opacity, low mass nature of the soot component of PM.

18% moisture, 70.3 lbs
Round pieces, 2 small pieces of white birch on top, 9 pieces
Stack sloped slightly towards kindling
Warm heater (132F firebox temp), cold fuel
Side ignition
Cold kindling, 3.5 lbs (not enough)
Almost identical load to run HK-J26 (very clean), except a borderline start, requiring one additional piece of kindling.
Interesting example of non-linear system -- high sensitivity to initial conditions.

Reference run.
This run was a best guess as to an optimum fuel loading and optimum air.
Very clean, low PM, low CO, good efficiency.
Stack temperature is hight, partly due to measurement location - see discussion for Series HKI
This run will serve as a benchmark for comparison for future tests.
