ABSTRACT The first part was the design and construction of a machine model using wood and the second part w pulverized coal-rice husk briquettes. The dt find the different loads due to shear stress on varlous parts or the nlachlne as the materials flow during consolidation. The loads obtained were used to dimension gears, shafts and pulleys that form the power transmission system of the machine. The machine was then drawn to produce a detail dimensional model in software form using AutoCAD. A soft copy of the drawings, the detail and assembly view is included in a couached at the back of this work. Briquette compositions of coal, rice husk and pa1111 "11 31LIt.tyC were produced at various compression pressures in the range from 20 to 451 i combustion characteristics were tested and evaluated.

The briquette density showed an increase from 527 to 1470.01kg/m3. Experiments performed revealed that a 5:3:1 ratio by weight of coal, rice husk and palm oil sludge gave the optimum calorific value of 19970KJikg. The result showed that the calorific value of rice husk has been improved, therefore putting an economic value to a rather waste material.
