Question

explain the structure of biogas plant.​

Answer 1

Explanation:

The biogas plant is a dome-like structure made of bricks and cement. It consists of the following five compartments: Mixing tank: Present above the ground level.

Answer 2

biogas plant is a unit which digests cow dung and organic waste materials to produce greenhouse gases such as methane, carbon dioxide.

Explanation:

• Biogas plant is a closed structure which breaks down organic material such as cow dung, vegetable and food waste and other organic waste substances under anaerobic conditions to produce biogas.
• These are units which largely produce methane and carbon dioxide which are highly combustible and so used as an alternative for cooking LPG cylinders.
• Structure : The plant is majorly classified into four parts Inlet, Digestion chamber (fermentation site), outlet and a Gas collector. All parts are present above the ground level except the Digestion chamber.
• Inlet is the part through which the Chamber is fed with waste products and a liquid sludge which activates the digestion.
• Digestion chamber is a doom shaped cylindrical chamber with a lid. The microbes break down the organic matter in anaerobic conditions to produce methane, carbon dioxide and other gases.
• Outlet is the passage for the the digested waste to be let out from the digesting chamber.
• Gas collector is the space which collects all the gas produced form the fermentation. The doom shaped lid on the Digesting chamber rises as gases accumulate in the collector. Rise in the level of the lid indicates that gas produced is being collected. This collector is connected to the gas stove.
