Biogas can be used for heating it?
At present, countries around the world have begun to use biogas as fuel and lighting. The use of biogas instead of gasoline, diesel, the effect of the machine is also very good. It has many advantages as rural energy. For example, the construction of an average l of 1.5 square meters of the fermentation tank, firewood and lighting problems can be basically solved throughout the year; people and livestock manure and crop straw and weeds, through fermentation, which generates methane, also can be used as a fertilizer, but also because of a high degree of maturity to make fertilizer higher manure biogas fermentation, the vast majority of parasite eggs were killed, can improve the sanitary conditions in rural areas, reduce the spread of diseases. Now, the application of biogas is spreading in many countries, and the development and utilization of biogas energy has achieved good results.
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.
Household biogas digesters in rural areas are mainly used for domestic fuel. Construction of a volume of 10 cubic meters of methane tank, put into the equivalent of about 4 pigs per day fermentation of raw materials, it can produce biogas can solve a family of 3 - 4 people lighting, cooking fuel. Biogas can also be used in agricultural production, such as greenhouse heat preservation, baking agricultural products, food reserves, fruit preservation, etc.. Biogas can also be used for power generation of agricultural machinery, large and medium-sized biogas production of biogas can be used to generate electricity, burning boilers, processed food, heating or supply of urban residents.
Biogas is a mixture of gases, mainly composed of methane (CH4) and carbon dioxide (C02). Methane accounted for 60% of the carbon dioxide accounted for a total of 30%, a small amount of hydrogen, carbon monoxide, hydrogen sulfide, oxygen and nitrogen gas, such as 40% of the gas, accounting for about 70%. As a result of combustible gas containing methane, so biogas can do fuel.
