目前我国的能源供应十分紧张,工农业的发展受到能源短缺的制约。由于能源供应严重不足,全国约有20％的工业生产能力不能发挥。因此有效地利用各种能源资源十分重要。一、煤矿瓦斯的利用价值我国,是以煤炭为主要能源的国家,煤炭占能源消耗的75％。大规模的煤炭开发,随着生产过程释放出了大量与煤伴生的矿井瓦斯,由于生产安全的要求,这些瓦斯都随着矿井通风排出地面进入大气。瓦斯的主要成份甲烷是一种高效、高热值和清洁的气体燃料和很好的化工原料。据测算,我国煤矿每年从总回风中排入大气的纯甲烷量达50多亿标米~3,按热值计算相当于1000万吨原煤,如果考虑利用热效率,相当于2000多万吨原煤的利用能量,若建设这样规模的煤矿,仅基建投资就需40亿元以
At present, China’s energy supply is very tight, and the development of industry and agriculture is constrained by the shortage of energy. As a serious shortage of energy supply, about 20% of the country’s industrial production capacity can not play. Therefore, it is very important to utilize all kinds of energy resources effectively. First, the use of coal mine gas value China, coal is the main energy country, coal accounts for 75% of energy consumption. Large-scale coal development, with the release of a large number of methane associated with the coal production process, due to production safety requirements, these gases are discharged into the ground as the mine ventilation into the atmosphere. Methane, the main component of gas, is a high-efficiency, high-calorie and clean gas fuel and a good chemical raw material. It is estimated that China’s coal from the total return air into the atmosphere each year, the total amount of methane reached more than 50 billion standard meters ~ 3, equivalent to calorific value of 10 million tons of raw coal, thermal efficiency if you consider the use of the equivalent of more than 20 million tons of raw coal Of the use of energy, if the construction of such a large-scale coal mines, infrastructure investment required only 4 billion yuan
