請容許我問一下.....

沼氣的成分

一氧化碳在哪裡?

Biogas is usually 50% to 80% methane and 20% to 50% carbon dioxide, with traces of gases such as hydrogen, carbon monoxide, and nitrogen.

貼錯了，抱歉。

清楚地說，這次氣爆地點在大學路的龍埔幼稚園前，屬龍學里
但是因為也會波及龍恩里的住戶 (二里以大學路 ...

ex: 為何一氧化碳濃度破表?

中華電信人員前往檢測，一氧化碳濃度遠遠超過標準35PPM近30倍，超標情況史上首見。

Biogas的成份Biogas is a mixture of methane (40 – 75%) and carbon dioxide (15 – 60%) with small amounts of other gases and by-products, i.e. nitrogen (0 – 2%), carbon monoxide (< 0.6%), hydrogen sulfide (0.005 – 2%), oxygen (0 – 1%) and ammonia (< 1%). Trace amounts of siloxanes (0 – 0.02%),
halogenated hydrocarbons (< 0.65%) and other non-methane organic compounds as aromatic
hydrocarbons, alkanes, alkenes, etc., are also occasionally present.
文中說carbon monoxide (< 0.6%)，若以體積濃度來說，應該就是小於 6000ppm....所以，沼氣中的CO達到1000ppm或是3000ppm應該都是正常的。
