Abstract
The Original Belonio Rice Husk Gasifier (OBRHG), initially of height of 0.6 m, diameter of 0.15 m
and thickness of 0.025 m was tested for biochar production through air gasification of rice husk
(RH) and the design was upscaled to height of 1.65 m, diameter of 0.85 m and thickness of 0.16 m.
A total of 27 experiments were conducted to monitor the gasifier performance and the system can
operate with the centrifugal blower operating at a power input of 155 W and a maximum flow rate
of 1450 m3/hr regulated according to the air requirement. Building the UBRHG is simple and inexpensive
to fabricate and with the fairly satisfactory performance and ease of construction along
with the convenience of operation, the UBRHG with RH as feed would find abundant avenues of
applications in a rural setting for biochar production alongside thermal, mechanical and electrical
energy delivery.
