Notes on readings
  • The flue gas opacity at this point represents the raw ohmeter readings. Scaling issues will be addressed
    once there is more data, and with some bench tests to determine % extinction.
  • There is drift in the opacity reading, either from the sensor moving, or the laser being absorbed by CO2. (Update, March 04/07: it appears that the laser is being absorbed by CO2, revised light source is described in HK-H11)
  • The dips after 70 minutes correspond to pokes of the fire, when the door was opened, and track the 
    red flue temperature readings.
