Answers
Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source. ... This energy release allows biogas to be used as a fuel; it can be used for any heating purpose, such as cooking.
Its uses: The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen.
Heya mate.. Here's your answer!
RAW MATERIAL USED FOR MAKING BIOGAS
In simple words: Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Anaerobic digestion (or biogas technology) is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas
USES OF BIOGAS
➡Biogas for home – cooking:
The biogas is transferred to the cooking place like kitchen from the digester through a tube. Except electricity, biogas when compared to other fuels produces less pollution while cooking. Need not wait for the heat after ignition. It produces instantly. Byproduct of biogas is used as fertilizer. It helps in producing indoor light.
➡Biogas for electricity:
External combustion engine – When biogas is combusted externally stirling motor is heated. It is heated with the help of heat exchanger. On the expansion of gas in the stirling motor electricity is generated.Since their efficiency is low and are expensive, their use is limited.
Internal combustion engine – Gas motors, gas turbines and diesel engines are some of the examples.
