Objective of this project is to generate electric power using bio gas.We use oil cakes and cow dung as feed for bio gas and this has worked excellently for our Bio Gas plant.
Idea is to generate electricity locally using dung bio gas.
This is an attempt to develop a model of producing electricity locally on small scale, and consume it within a short distance.
What is bio gas?
Bio gas is a mixture of gases, usually carbon dioxide and methane. It is produce by as a result of anaerobic decomposition of organic matter such as vegetable waste, animal waste. It is produce by a few kind of micro organism.
The active main flammable component is methane. Advantage of methane is that it dose not produce harmful carbon monoxide gas. So it is very good to use it in home.
As compare of with commercially available natural gas, Bio Gas contain a large preparation of carbon dioxide. So it is needed to remove such contain before using Bio Gas in IC engine. Process of filtration is important factor while using Bio Gas in internal combustion engine.
Approximate gases content in Bio Gas :-
- Methane(CH4) - 66.5%
- Carbon Dioxide(CO2) - 30.5%
- O2+N2 - 0.5%
- Humidity - 2.5%

COMPARISON OF CALORIFIC VALUE OF VARIOUS GASES
- Producers gas:-1200kcal/cum
- Landfill gas:-4000-5000kcal/cum
- Bio Gas:- 4500-6000kcal/cum
- Natural Gas:-6800-8000kcal/cum
