Flue Gas Analysis

• Ashbox door closed (air cut back) when stack temperature reached 320F (18 minutes). Both bells were closed at 
  start, opened at 22 minutes
• At 20.5 minutes, the wood pile fell towards the glass. It was poked back straight at 60 minutes.
• The lowest CO/CO2 ratios ever were recorded during this run (.0012). See Testo data file.
• Spikes in stack temp 60 minutes and after correspond to pokes.

Quite a clean start for white birch. A small hot kindling fire went to the rear corner immediately. Not too much
bark was exposed to the kindling (see stacking photo), so startup was very controlled compared to other birch runs.

Opacity

The small spike at 60 minutes was when the pile was poked back upright, after falling towards the glass at 20.5 minutes.
