    瓦斯發電機組進行發電需要滿足哪些條件?

    1、瓦斯的濃度。瓦斯爆炸發生的濃度界限指的是瓦斯與空氣的混合氣體中瓦斯的體積濃度。當瓦斯濃度達到9.5%時,理論上瓦斯可以同空氣的氧氣安全反應,從而放出更多的熱量,因此爆炸的強度;當瓦斯濃度低于5%時,由于參加化學反應的瓦斯較少,不能形成熱量積聚,因此不能爆炸,只能燃燒;當瓦斯的濃度高于16%時,由于空氣中氧氣不足,滿足不了氧氣反應的全部需要,只能有部分的瓦斯與氧氣發生反應,所生成的熱量被多余的瓦斯和周圍介質吸收降溫,所以也就不能發生爆炸。
    1. Gas concentration. The concentration limit of gas explosion refers to the volume concentration of gas in the mixture of gas and air. When the gas concentration reaches 9.5%, theoretically, the gas can react safely with the oxygen in the air, thus releasing the most heat, so the explosion intensity is the largest; when the gas concentration is lower than 5%, due to the less gas participating in the chemical reaction, it can not form heat accumulation, so it can not explode and can only burn; When the gas concentration is higher than 16%, due to the lack of oxygen in the air, it can not meet all the needs of oxygen reaction. Only part of the gas reacts with oxygen, and the heat generated is absorbed and cooled by the excess gas and surrounding media, so the explosion can not occur.
    2、充足的氧氣含量。瓦斯與空氣混合氣體中氧氣的濃度必須大于12%,否則爆炸反應不能持續。煤礦井下的封閉區域、 采空區內及其他裂隙等處,由于氧氣消耗或沒有供氧條件,可能出氧氣濃度低于12%的情況;其他巷道、工作場所等按規定氧氣含量不得低于20%,一般不存在 氧氣濃度低于12%的情況 ,因為在些情況下,人員在短時間內就會窒息而死亡。
    2. Adequate oxygen content. The concentration of oxygen in the mixture of gas and air must be more than 12%, otherwise the explosion reaction cannot be sustained. Due to oxygen consumption or lack of oxygen supply conditions, the oxygen concentration may be lower than 12% in the closed area, goaf and other fissures under the coal mine; the oxygen content in other roadways and workplaces shall not be less than 20% according to the regulations, and generally there is no case of oxygen concentration lower than 12%, because in some cases, personnel will suffocate and die in a short time.

    3、足夠能量的點火源。點火源能夠引起瓦斯爆炸的三個條件是:(1)溫度不低于650度。(2)能量大于 0.28mJ.(3)持續時間大于爆炸感應期。這三個條件通常很容易滿足,如明火、煤炭自燃、撞擊火花、電火花等。在煤礦開采過程中,對一些不可避免的火源有時需要采取特殊的技術,使其不能滿足瓦斯的點火條件 。例如:井下爆破時所用的毫秒雷管產生的火焰,其他溫度主達2000度,但持續的時間很短,小于爆炸感應期,因此不會引起瓦斯爆炸。
    3. Ignition source with enough energy. The three conditions for ignition source to cause gas explosion are: (1) the temperature is not lower than 650 ℃. (2) (3) the duration is longer than the induction period. These three conditions are usually easy to meet, such as open fire, coal spontaneous combustion, impact spark, electric spark, etc. In the process of coal mining, some inevitable fire sources sometimes need to adopt special technology, which can not meet the ignition conditions of gas. For example: the flame produced by millisecond detonator used in underground blasting, other temperatures are mainly up to 2000 degrees, but the duration is very short, which is less than the induction period of explosion, so it will not cause gas explosion.
    利用瓦斯發電需要滿足一定的條件,我們知道瓦斯的主要成份是甲烷(CH4),它是一種無色無味的可燃性氣體,當瓦斯濃度在5%-16%時,遇明火會發生爆炸,當濃度在9.5%時爆炸的威力,當瓦斯濃度大于16%,遇明火,瓦斯會只燃燒不爆炸,我們利用瓦斯發電機組進行發電,要使瓦斯氣源的濃度達到爆炸范圍(更好是9.5%),此時爆炸產生的化學能,發電效率也就。除了瓦斯濃度外,發電對瓦斯的溫度、壓力、水分含量與雜質粒度等也有一定的要求:
    We know that the main component of gas is methane (CH4), It is a kind of colorless and tasteless combustible gas. When the gas concentration is 5% - 16%, it will explode in case of open fire. When the concentration is 9.5%, the explosion is the most powerful. When the gas concentration is greater than 16%, the gas will only burn but not explode in case of open fire. We use the gas generator set to generate electricity, so as to make the concentration of gas source reach the explosion range (preferably 9.5%), At this time, the chemical energy generated by the explosion is the largest, and the power generation efficiency is the highest. In addition to gas concentration, power generation also has certain requirements for gas temperature, pressure, moisture content and impurity particle size
