Experimental investigation on biochar from groundnut shell ...

A continuous process for the production of biochar is considered one of the most promising thermochemical biomass energy conversion processes other than batch processes (earthen and mound kiln, metal kiln, retort, etc.) because of its higher biochar yield of 25 to 35% and its greater flexibility regarding biomass feedstock .

Biochar Retort Pyrolysis: Adapting a Bell-style RMH ...

There is an inner retort,probably about 30 gallons, with an opening for the woodgas pipe to screw into. A 55 gallon barrel surrounds that and mates up with the lower barrel to form the bell. It has a chimney stub and a place for the woodgas piping to pass through. The third barrel is probably a 55 gallon barrel cut and expand with additional metal.

Small Scale Devices for Production of Biochar

TLUD Gasifiers Can Make Biochar •Flaming (glowing) pyrolysis with very limited supply of air. This is NOT a retort. •Usually 15% to 22% yield of biochar by weight. •Control of primary air supply impacts the characteristics (quality) and quantity of biochar. Can make "designer biochar" with forced air.
