gas analysis
Flue gas.
Note that time values are offset by 18 minutes.
Mild overamping at 50 minutes. Small wood, hot firebox. Note high stack temperature due to previous fire.
Also note, before start, when flue damper is opened, flue temperature jumps from 90F to 200F on standby.

TESTO Excel data file

Note that first peak is due to startup, with no corresponding CO peak. Second peak happens during overamping
(low oxgyen, 8.0%), and corresponds with the CO peak. After 52 minutes, opacity is zero. Actually, it dips
slightly below zero, which is characteristic. This may be because of the hotter gas at this stage of the burn.
