HK-K05 - January 12th, 2009

Notes

• Warm heater. Surface temperatures are being tracked for damper comparisons, and data will be added later
• Damper left open, with cold air bypass open.
• White birch, 20% moisture
  
• 6 pieces, 4.5 lb kindling, 63.4 lbs total
• Large CO and PM spike about 15 minutes in.
• 5% efficiency loss due solely to CO, about 3% higher than normal.
• Grate air inadvertently closed for entire run.
• 2.29 g/kg PM (Condar)
• 45.5 g/kg CO
• 71.9 % overall efficiency

Animation

Flue Gas

The flue gas probe and its filtering system had a malfunction that was corrected at minute 38. Condar spreadsheet gas data, to allow calculation of a PM number, was estimated for the first 35 minutes, by using the data from the previous test.

Opacity

PM number is higher than previous tests, at 1.5 g/kg. Could be due to kindling mis-start, which required adding additional newspaper. Kindling pile was lit from top, but used less newspaper layering than previous tests, resulting in a mis-start.

Statistics

Fuel stack

Fuel stack. Kindling is on the right side, layered with newspaper. Ignition from top of kindling. Kindling stack used less layering with newspaper, and resulted in a mis-start.
