Biochar is created through the thermal treatment of biomass in a high temperature, indirect-fired rotary kiln, a process referred to as pyrolysis, sometimes also called torrefaction, though torrefaction tends to refer specifically to the pyrolysis of wood biomass. Biochar can be created from any form of biomass – animal by-products

The torrefaction is a heat treatment which aims to modify the properties of various wood varieties. Unlike a conventional drying, torrefaction is done at high temperature, in the range of 160 C to 250 C [320 F to 490 F]. The torrefied wood develops increased resistance to deterioration, fungal attack as

The small-scale rotating drum reactor (SS-RDR) was designed and constructed without using purge gas for the purpose of household application. The thermal and torrefaction characteristics of SS-RDR were studied and compared with other reactor types. It was found that the heat loss at the reactor wall and heat loss from exhaust gas of the SS-RDR were in the range of 6.3–12.4% and 27.9–42.8%

Jun 01, 2015 International audience; Rotary kilns are well suited for processing woody biomass by torrefaction to produce bioenergy. One of the key issues for process design lies in the flow pattern modeling.

TORREFACTION. When we crafted our first dryer, over 70 years ago, we simply needed a dryer that worked – we didn’t have time for anything less. We needed a dryer that was reliable, efficient and built with the understanding that capacity is king. So, we built one ourselves. As owner-operators of the same equipment you use we understand your
