[Stoves] Box-1 Fuel

[Frank Shields]

Stovers,

Box-1 Fuel test package

I am thinking the following are the properties of biomass that effect 
the small stove combustion process. And that the constituents listed 
cross all biomass boundaries. No need to say ‘oak’ or ‘pine-cones etc. 
It covers the range from Richards briquettes, rice burners, dung, stick 
wood and chips.Although the test methods may not perform to ASTM 
procedures they are designed to be easily performed in any small 
backyard lab and results in the working range of biomass. The list is as 
follows:


1)Particle size distribution

2)Width to length ratio

3)Volatile matter (DAF)

4)Fixed matter (DAF)

5)Ash (dw)

6)Solvent extracted (resins etc.)

7)Water extracted (sugars & starches etc.)

8)Particle density (using free flowing sand)

9)Bulk density

10)%void space (from 8 and 9)

11)electrical Conductivity (determine soluble salts)

12) Moisture

Extra tests added where needed like toxic metals, durability, 
carbonates, acid soluble ash, neutralizing value and more..

Regards

Frank
