HK-K04 - January 11th, 2009

Notes

• Warm heater. Surface temperatures are being tracked for damper comparisons, and data will be added later.
  
• Damper closed at end of run. (Jan 17/09: damper was found not to be closing all the way. See notes in the Test Series.)
• White birch, 20% moisture
• 6 pieces, 4.5 lb kindling, 63.7 lbs total
• Equipment malfunction from minute 0 to 35. Gas values during that interval estimated from previous test.
• Kindling mis-start, see details below. Higher PM than previous tests, at 1.5 g/kg.
  
• Grate air inadvertently closed for entire run.
• 1.47 g/kg PM (Condar)
• 17.0 g/kg CO
• 71.7 % 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 an 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 an mis-start.
