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
Animation, 2 minute intervals.
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.
TESTO Excel data file
Condar Spreadsheet Results
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.
Condar Spreadsheet (includes detailed fueling data)
Fuel stack. Front to back, largest pieces on bottom, kindling on top.
