进入盛夏,随着气温的不断升高,农民家中沼气池的沼气产量往往是“供大于求”。夏季是农村户用沼气池产气高峰期,也是极易诱发各类安全事故的高危期。因为沼气是一种易燃易爆的气体,一个火星就能点燃,而且燃烧温度很高,在密闭状态下,空气中沼气含量达到8.8%时,只要遇到火种,就会引起爆炸。 Into midsummer, with the rising temperature, biogas digesters in farmers’ biogas production is often “oversupply ”. Summer is the peak of gas production in rural households digesters, but also highly vulnerable to all types of high-risk accidents. Because biogas is a flammable and explosive gas, a Mars can ignite and the combustion temperature is very high. When the biogas content in the air reaches 8.8% in the closed state, it will cause an explosion whenever a fire is encountered.
