Maple, 18% moisture, 78.0 lbs
5 round pieces of maple, with 3 pieces of white birch on top, 2 on bottom, 10 pieces total
Warm heater (162F firebox temp), cold fuel
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.
Animation, 2 minute intervals.
TESTO Excel data file
Note that the opacity spikes lag the CO spikes, and there is no corresponding opacity spike for the CO spike at the end.
