What is Bio-gas Generator or Biogas Plant

The bio-gas generator or biogas plant is the small where bio-gas is produced from the biomass waster materials like cow dung. The figure below shows a typical bio-gas generator or biogas plant which uses cow dung for production of biogas. Cow dung is produced in huge quantities especially in the countries that are major producers of milk like India, Australia, US, China and others. The cow waste which would have created the environmental pollution can be effectively used for producing biogas, which is an excellent sources of renewable energy. This biogas can be used
for cooking and heating.

The bio-gas generator or the biogas plant shown in the figure uses process of digestion for production of biogas. Digestion is the biological process that occurs in the absence of oxygen, but in the presence of anaerobic organisms at atmospheric pressure and temperature of about 35-70 degree Celsius. The main part of this biogas plant is the digester where digestion process occurs.

Parts of Bio-gas Generator or Biogas Plant

Let us see the various parts of this biogas plant or bio-gas generator:

1) Foundation: The biogas plant shown here has been built within the surface of the earth underground and it is on the foundation that the whole biogas plant is based. The foundation forms the base of the digester where the most important processes of biogas plant occur. The foundation base of the digester is made up of cement concrete and brick ballast. The construction should be built in such a manner that it should be able to provide stable foundation for the digester walls........
