Lab Notes

Gas graph.
Oxygen drop at 10 minutes indicates when Testo problem was fixed.
Stack temperature drop at 75 minutes indicates when air supply was cut approx 90%.
The very high stack temperatures compared to earlier runs, indicates that the air slots in the firebox have too much inlet area.
Test MHA-1611 will be a repeat of this one, with the air left wide open.
Then, for test MHA-1612 we will reduce firebox air slots.
