HK-K17 - February 6th, 2009

Notes
  • Cool heater - damper and ashbox door had been left open from yesterday's burn
  • White Birch, 20% moisture
  • 12 pieces, 4.5 lbs kindling, 64.4 lbs total
  • Smaller pieces, stacked front to back. Kindling on top.
  • No CO spike at the beginning, a very significant result.
  • Data problems with Testo analyzer, see notes below gas graph.
  • Ashbox door closed, air inlet left open 50% to simulate a slightly leaky heater. Damper left open.
  • Cold air bypass closed.
  • 0.93 g/kg PM (Condar)
  • 13.9 g/kg CO
  • 76.7 % overall efficiency
  • Very good numbers, but not reliable due to data loss. See notes with gas graph.

  • Equipment problems. First 18 minutes missing, data loss due to power failure. Values estimated from memory.
  • Testo malfunction between 42 minutes and 80 minutes - data interpolated between adjacent values.

  • Ashbox door was closed at 101 minutes, and air control closed 50%. Only gas data up to 101 minutes was used to calculate efficiency and emissions.

Good numbers, but not reliable, see notes on gas graph, above. However, a very interesting result for small wood, due to the absence of the usual CO spike at the beginning.
