Test MHA-1801
January 15, 2018
Red oak, same batch as last test series of 2017
Log cabin stacking, top ignition
61.50 lbs including 1.5 lbs kindling
21.7% moisture. 2344 stacking.
Pisla HTT 602 door, 22" wide
Austrian eco firebox, see http://www.heatkit.com/research/lopez-2014-03-01.html
See 2017 Run #16 (final run) of a repeatability study with a new test fueling protocol under development.
The 2018 series is a "substantially similar" study for possible use in certifying factory made heaters,
to allow laboratory testing on one model to apply also to variations on that model.
For this run, we are repeating the last series of 2017 as a baseline for comparison.
Condar spreadsheet results, calculated at 90 minutes.
With the eco-box, the test is over when the air supply is closed. Remaining charcoal would normally be burned in the next fire.
Notes:
This run was done from memory. The stacking was 2344 instead of 2345.
The kindling was 1.5 lb instead of 2.0 lb. Last year, we went from 1.5 to 2.0 because the top kindling was not "catching" the
pile fast enough. You can see the same phenomenon on the red temperature curve, below.
Note that PM is 1.43 g/kg vs 0.65 g/kg for the last run of 2017
