Abstract: Biomass briquetting is a process which converts agro residue and saw dust materials with low bulk density into a uniform size and more convenient households or industrial fuel product. The major advantages offered by biomass densification are related to handling improvement and increasing calorific value per unit volume. In general this process offers energy generation opportunity from any biomass residue. Maichew Particle Board Factory generates a huge amount of dust particles from its different lines which recovered using different cyclones. But this recovered waste doesn’t use as a fuel for boiler or dryer and also not yet convert to any valuable product. It is simply disposed to the environment. Therefore, the objective of the project was to study an integrated briquetting plant for Maichew Particle Board Factory which converts the waste dust particle in to valuable product. This case study involved the overall energy review of Ethiopia and briquetting process in detail. According to the selection of appropriate technology which converts the eucalyptus dust to high quality briquette fuel screw press extruder with a pre heater and heated die coils has been chosen. In addition the amount of energy required to convert the dust particle to briquettes is also evaluated. Based on the results of this study, the economic evaluation of the integrated briquetting plant for Maichew Particle Board is feasible besides to its socio environmental benefits. It is an investment which can recover its capital with almost two years.

Abstract: One of the major problems concerning the use of solar panels for heating is the low level of thermal interchange with air in the dynamic vein of the solar panel. This weakness in such systems does not enable an optimum performance or high level of thermal efficiency to be obtained from their use. There is, however, a very noticeable improvement to thermal transfer when baffles are placed in rows in the ducts. To conduct the experiments, solar energy was simulated, the aim being to improve the ratio between temperature and thermal efficiency of an air heating plane solar panel and to make use of the system to reduce the drying time of papayes.
