Answers
Answer:
Explanation:
1. The digester is a sealed chamber in which there is no oxygen. Anaerobic micro-organisms that do not require oxygen decompose or break down complex compounds of the cow-dung slurry. It takes a few days for the decomposition process to be complete and generate gases.
2. Because this decomposition happens in an anaerobic environment, the process of producing biogas is also known as anaerobic digestion. ... Due to the high content of methane in biogas (typically 50-75%) biogas is flammable, and therefore produces a deep blue flame, and can be used as an energy source.
3. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical power into electricity. Mechanical power can also be utilized directly for specific tasks such as pumping water.
4. Wind power projects depend primarily on wind speeds for generating electricity, and therefore, have lower fuel availability risks than other conventional sources of power generation. ... Since, wind power is primarily dependent on wind speeds, it is exposed to the vagaries of nature.
5. Producing biogas gives many advantages for the environment, companies and people involved. The advantages are: Biogas is a green energy source in form of electricity and heat for the local grid. Considerable environmental advantages - less emission of the greenhouse gasses methane, CO2 and nitrous oxide.
6. Image result for Biogas is also know as
Biogas is a renewable energy source. In India, it is also known as "Gobar Gas". Biogas is produced by anaerobic digestion with methanogen or anaerobic organisms, which digest material inside a closed system, or fermentation of biodegradable materials.
7. Anthracite is a natural smokeless fuel. Unlike bituminous coal, which produces a thick, black smoke and has a high sulphur content, anthracite has the highest carbon content of any coal and burns cleanly.
8. An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.
9. A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
10. Biogas Production from a mixture of WaterHyacinth, Water Chestnut and Cow Dung. There is an increasing need to replace conventional energy with the renewable energy to save our natural resources and our environment. The three variants were charged into a 20L portable bio-digester in the ratio of 1:1 with water.
11. The gas demand can also be defined using the daily cooking times. The gas consumption per person and meal lies between 150 and 300 liter biogas. For one liter water to be cooked 30-40 l biogas, for 1/2 kg rice 120-140 l and for 1/2 kg legumes 160-190 l are required.
12. 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.
