[Stoves] oven-dried vs sun-dried biomass and TLUD stoves

[Richard Stanley]

Rajan, 
That was a brilliant elucidation of the progression of the combustion process. Thanks much.

When we oven dry the water-saturated   briquette as it comes out of the mold, versus drying it in ambient well but naturally ventillated conditions (3 to 5 days generally) the sun dried bq preforms better every time. Had never really considered why until you elaborated the sequence of combustion and products there to.  

For us, natural drying– with maximum surface area exposure–is also important, because uneven drying generates uneven shrinkage which in turn tends to shear  the randomly arranged fibers which hold the bq together.

Dear All,
 
I have a feeling that oven-dried biomass if used in a TLUD stove can lead to higher "particulate matter" emissions from the stove - which can be a health hazard.
 
So, probably a moisture content of around 10 to 15 % ( not more ) in the fuel has a positive role to play.
 
The best sun-drying may be giving us this moisture content.

Rajan
