Synthesis gas formation which can be transformed to useful compounds through biomass
gasification is perceived as one promising process of biofuel production. A construction, design and
development of an efficient and small-scale wood-fired gasifier prototype was made at Batangas State
University. This study included the costs and specifications of materials, the design, components and
percent conversion of the biomass to syngas by obtaining the amount of the residue. Set of operating
conditions were determined so as to achieve a good performance of the gasifier; otherwise it adversely
affected the operation of the prototype. The gasifier operates in a condition in which the air flow rate is
560 - 610 cm3
/min wherein the valve is half-open and the blower is turned on after 20 seconds. The
gasifier will be closed after a minute of start-up. With these conditions, the gasifier works accordingly to
a smooth operation. Syngas was composed of methane (2.32 % volume), carbon dioxide (10 % volume),
carbon monoxide and minimal amount of hydrogen. Two (2) kg of woodchips with 90.75% conversion
was the best amount of feed suited for the operation of the gasifier. This innovation comprises a method
which efficiently converts the feedstock thereby enhancing the energy of the syngas produced with byproducts
at minimum acceptable value. The wood-fired gasifier will be a very helpful tool in contributing
to the resolution of pressing social and environmental problems such as energy security and local
agricultural waste pollution.
