HK-K16 - February 5th, 2009

Notes

• Warm heater
• White Birch, 20% moisture
• 9 pieces, 4.5 lbs kindling, 63.6 lbs total
• Smaller pieces, kindling stacked tighter than HK-K15, to slow down start
• Slower start. CO and PM spikes, delayed and smaller than HK-K15.
• Air left open, flue damper left open. Data collection stopped at 120 minutes.
• Very low efficiency at the end, which reduced overall average to 70.0%, slightly lower than others
• This is a reference run to get surface temperature data for a cycle with damper open plus ashbox door open (worst case).
• 1.12 g/kg PM (Condar)
• 24.99 g/kg CO
• 70.0 % overall efficiency

Flue Gas

Air left open, data stopped at 120 minutes. Extended data is available in Excel file, below.
Slow, clean start. Delayed spikes, lower spikes. Compare with yesterday (HK-K15).

Opacity

Slightly less than yesterday, even though wood was even smaller. Due to slower start. Not enough air for large load of small wood, or firebox too small.
