The Research aimed to use the technology of the fermentation to produce the biogas from the cow manure. The digester has benn carried according to the Indian model. The digester consit of one cylinerical tank with 9.42m3 volume (height 3m, diameter 2
m) and gastank with 6m3 (height 1m) and inlet pipe and outlet pipe. The study showed the following:
The accumulated production of biogas was through the 30 days retention time 48m3. The heighest production was in the thirteenth day with 4.5m3. The farm became after the use of digester clean and with little insect and smell.
With use 1m3 of biogas could we use one cooker for 2.5 hour and with the same quantity could we use one inner combustion diesel motor (90% biogas and 10% diesel) for half an hour.
3/4m3 from digester volume is enough for one cow with 12 kg manure daily. So we can design the suitable digester for any farm.
The power supply in remote areas has been usually provided by thermal power plants, usually diesel
generators. Recently the use of renewable resources to generate electricity and protect the environment
increased rapidly. Hybrid power systems may c
onstitute the most economical solution in many
applications in the near future, especially for electrification remote area.
Hybrid systems by definition contain a two sources or more of power generation (or storing) to supply
electricity to the loads. These sources may be pure traditional, traditional and renewable, or may be
renewable only.
This paper describes a case study for a remote area. It shows importance of using the hybrid system to
electrify a remote area. The suggested hybrid system consists of wind turbine, PV, traditional generator,
and batteries to supply a load (72 kWh/d). A real wind data related to Alsukhna near Homs is used. We
perform a technical and economical analysis using Homer to determine the optimal design of a hybrid
System for a Reliable Load Supply in Remote Area with least cost.
