In this article, sawdust, rice husks, peanut shells, coconut fibres and palm fruit fibres were densified into briquettes at modest pressures of 5-7 MPa using a piston and die type of press.Abstract:
Biomass material, including sawdust, rice husks, peanut shells, coconut fibres and palm fruit fibres, was densified into briquettes at modest pressures of 5–7 MPa using a piston and die type of press. The briquettes were tested to evaluate their relaxation behaviour, mechanical strength and burning characteristics. The sawdust briquettes were found to have better overall handling characteristics. But briquettes of different biomass materials required different optimum conditions of fabrication and generally showed a promising potential for further development.read more

Compression of straw to high densities in closed cylindrical dies
M.J. O'Dogherty,J.A. Wheeler +1 more
TL;DR: In this paper, the authors reviewed the literature on the compression of straw and grass in closed dies and conducted experiments to establish the pressure-density relationship for straw and found that at densities of 350 kg/m3 the wafers were durable and could be formed at pressures in a range 12-31 MPa.

Durability and relaxation of sawdust and wheat-straw briquettes as possible fuels for Kenya
Lucy Wamukonya,Bryan M. Jenkins +1 more
TL;DR: In this paper, a study was conducted to determine the possibility of producing durable briquettes from wheat straw and sawdust as fuel for Kenyan households and small-scale industries, and the results showed that wheat straw was the least durable and expanded most, while blending straw with sawdust improved this durability considerably.

The briquetting of wheat straw
TL;DR: In this article, the authors demonstrate that wheat straw can be compressed to a relative density greater than unity, and stabilized at that density without binding or other mechanical aids, which represents a reduction in the volume of the material by an order of magnitude, so the straw could be transported and stored more economically than is possible at present.

A review of the mechanical behaviour of straw when compressed to high densities
TL;DR: In this paper, the authors reviewed the available information on the formation of high density briquettes in closed and tapered dies and classified the information under four broad aspects, namely: (1) the physical properties of straw, (2) the compression characteristics, (3) the formation, and (4) theoretical considerations of compression.

Theoretical analysis of the compression of fibrous agricultural materials
M.O. Faborode,J.R. O'Callaghan +1 more
TL;DR: In this paper, a model for analyzing the compression behavior of fibrous agricultural materials is proposed, which uses a single equation for the compression function, which may be separated into two parts.
