<br class="">
I believe the test package I put together would answer your questions. That because when working on the procedures and selecting the different tests I had what you are referring to in mind. They include test like:<br class="">
Moisture, size distribution, particle shape, particle density, bulk density, void space (for air flow), volatiles and fixed carbon using the pipe method, Ash and ash properties, - I think that is about it as I remember. I had some other ideas using air flowing artificial ’smoke’ but to lack of interest never followed through.<br class="">
Then we need to correlate the results from the above tests to determine how they relate to a stove performance. That I never attempted but I do think I have all the methods and tests that is appropriate to do the job.<br class="">
