Is it harmful to human body?
Methane is the main component of methane. The gas from the 50% ~ 80% methane (CH4), from 20% to 40% carbon dioxide (CO2), 0% ~ 5% nitrogen (N2), less than 1% hydrogen (H2), less than 0.4% oxygen (O2) and 0.1% ~ 3% hydrogen sulfide (H2S) gas composition etc.. Because the methane contains a small amount of hydrogen sulfide, so slightly smell. Its properties are similar to that of natural gas. If the air contains 8.6 to 20.8% (by volume) of methane, it will form an explosive mixture of gases.
No harmMethane is not toxic to people, when the concentration is too high, so that the oxygen content in the air is significantly reduced, so that people suffocate. When the methane in the air reaches 25%-30%, it can cause headache, dizziness, fatigue, lack of concentration, breathing and heartbeat, ataxia. If you do not stay away from time, can cause suffocation. Skin contact with liquefied methane, can cause frostbite.
Methane is the main component of methane, and gas, like gas harmless... Ease of use
Methane is the main component of methane is a kind of ideal gas fuel, it is colorless and tasteless, with the appropriate amount of air will burn after mixing. The 34 million coke heating per cubic meter of pure methane, calorific value per cubic meter of biogas is about 2080023600 kj. That is, 1 cubic meters of methane completely burned, can produce equivalent to the amount of heat supplied by 0.7 kg anthracite. Compared with other gases, the utility model has the advantages of good antiknock performance, and is a good clean fuel.
