[Stoves] combustion of char -- spontaneous and dangerous

[Crispin Pemberton-Pigott]

Dear Friends
 
Here is a mass profile, raw and smoothed with 21 point simple averaging
(minus 1000 to pull it down so you can see it).
 


 

There is a clear sustained increase in the mass after about 800 minutes
(readings are per 10 seconds). The jumping around in the middle of the night
is, I believe, wind on the chimney. I am quite prepared to believe that the
effect of wind might explain 100% of the change in the line, but it is worth
looking at the whole fuel composition issue just in case there is something
new to learn.

 

Regards

Crispin
