2019 MHA Research Heater Tests

Test MHA-1912
February 13, 2019

Random loading, white birch, log cabin stacking, top ignition. Cold firebox, cold fuel
Pieces loaded in order of increasing weight. 2344 stacking.
60.34 lbs including 2.0 lbs kindling
Estimated moisture 15%.
Run #6 of a cold firebox test series. Heater fired every 2nd day.
The Testo data was started 10 minutes before the test.
CO spike at the beginning, high PM from birch bark burning at around 10 minute mark.
See sequence photo and lab notes, below.

Pisla HTT 602 door, 22" wide
Austrian eco firebox, see http://www.heatkit.com/research/lopez-2014-03-01.html

This was the 10th full run using the new automated Condar controller

Lab Notes

Testo gas graph. Interesting comparison with previous run.
Demonstrates the greater variability with a cold firebox, more sensitivity to initial conditions, kindlling stacking, ignition sequence.

Burn sequence. Time lapse taken at 2 minute intervals. White square marks 90 minutes.
