Abstract

The effect of binder types (bananas, yams, and cassava) and binders proportion on thermal properties of waterlily (Nymphaea lotus Linn.) briquettes were investigated. Peels from bananas, yams, and cassava were collected from agro processing cottage industry. The peels were washed, sun-dried, and ground using a disk mill and Tyler sieves to a particle sizes of 0.50 mm. The waterlily plants were collected from the river using a drag net, sun-dried, then ground and sieved to a 1.18 mm particle size. Respective agro-waste grinds at 20% (B1), 40% (B2), 60% (B3), and 80% (B4) of a constant weight of water lily grinds were blended together after addition of 200ml of boiled water. The resulting homogenous feedstock was then fed into a steel cylindrical die of dimension 14.21cm height and 2.14cm diameter, and compressed by hydraulic compression machine at pressure level of 5 MPa with dwell time of 20 second before ejected for further experimentation. From the results of the study, calorific value of waterlily briquettes ranged from 24751kJ/kg to 26717kJ/kg. The values obtained in this study are above 17000kj/kg threshold minimum calorific value by standard (DIN 51731:1996-10) for fuel sources, hence they are suitable for household and for small industrial heating applications. Because the ash content increased and the calorific value decreased beyond 60%, it can be concluded that the ideal amount of binder recommended across the binders for the production of waterlily briquettes is at 60% and below, even though the combustion properties generally improved with an increase in binder concentration.

Keywords: Biomass, densification, agro wastes, aquatic plants, density, briquette
