Design, manufacturing and evaluation of Portable bio gas unit for use in Nomads areas

Abstract

An experiment was conducted at Al -kalakla Quba town, Khartoum state - Sudan. The objective of the study was to design, fabricate and evaluate a portable biogas unit to be used in rural communities. The unit was fabricated using steel barrel designed from a barrel as a portable container and the abundant cow dung as a substrate. The cow dung was left for ten days in the digester before the first reading .Reading were taken for twenty days .the successive reading showed an increasing rate of gas production. The fabricated unit is mobile carried on a cart for transportation in nomad areas and it can work as affixed unit wherever it needed. The results showed that small amount of gas was from this unit and this is due to the small size of the unit fabricated. Despite this fact the gas produced from the designed unit satisfied the daily need of a rural family.
