How to produce biogas at home
It is estimated that in the United Kingdom, the use of human and animal waste, the methane produced by anaerobic digestion of microorganisms, can replace 25% of the UK's total gas consumption. Scotland has designed a small methane engine that can be used in villages, farms or homes.
The basic principle of biogas production is still under exploration. The biogas formation process can be divided into two stages, the first will be a variety of complex organic compounds into lower fatty acids, such as butyric acid, propionic acid and acetic acid; and then the various products into methane and carbon dioxide etc..
Methane, as its name implies, is the gas in the swamp. It is often seen in the marsh, sewage ditch or septic tank, there are bubbles out, if we hit a match, it can be lit, which is naturally occurring natural gas. Methane is a kind of combustible gas, which is produced by the fermentation of microorganism under the condition of isolating air (reducing condition) and suitable temperature and humidity. Methane is the main component of methane, accounting for about 60% of the gas produced by a variety of 80%. Methane is a kind of ideal gas fuel. It is colorless and odorless. The 34000 joules per cubic meter of pure methane for heating, heating per cubic meter of biogas is about 2080023600 joule. That is, 1 cubic meters of methane completely burned, can produce equivalent to the amount of heat supplied by 0.7 kg anthracite.
