CityGas管道气成份
CityGas管道气成份昨晚才知道，坡上管道燃气不是天然气，而叫town gas，主要成份是氢气！
大家请看EMA官方文件

第13页，
7.1 Gas Specification
Typical Town Gas Composition
Hydrogen 53.0~65.0
Methane 3.0~20.0
Ethane 0.1~2.0
n-Pentane 1.0~2.7
i-Pentane 1.0~3.7
Carbon Monoxide 2.0~6.0
Carbon Dioxide 11.0~23.0
Nitrogen 2.0~5.5
Oxygen 0.5~1.5
单位体积热值只有天然气的一小半啊！
PS. 坡上天然气的成分甲烷至少要80%.

CityGas 官网也有描述

Water vapour represents the bulk of the by-products produced during the combustion of town gas. This is because the main component of town gas is hydrogen and during combustion, hydrogen will react with oxygen in the air to produce heat and water vapour. As a result, town gas emits less carbon dioxide during burning as compared to natural gas and LPG.
