Test HK-K24
February 14/09
Slightly warm heater. Large load 48 hrs previous, damper closed
White Birch, 20% moisture
Very large pieces. 8 pieces, 4.5 lbs kindling, 73.5 lbs total
Pieces stacked front to back. Kindling on right side, lit from top
Very fast and clean start. 2pc left-to-right on rear grate, to provide delayed ignition from
the grate location. This was a mistake - load overamped, very high CO
starting at about 10 minutes
Low PM, high CO. Efficiency loss from CO alone was 4.6%
Data for calculation stopped at 90 minutes, when air control was closed.
Cold air bypass open. Doors not taped. Flue damper shut 2 hrs after air was shut.
Animation, 2 minute intervals.
Flue gas
Time on gas graph is offset by 19 minutes.
Huge initial spike from the bad start. Not really reflected in the final number, which is a reasonable 1.12 g/kg.
Opacity
Condar Spreadsheet Results
Condar Spreadsheet (includes detailed fueling data)
Fuel stack. Front to back, two large pieces on the bottom. Second row stacked tight to the
back, to prevent premature ignition from the grate.
Fuel pieces, numbered 1 - 8 from heaviest to lightest piece.
