@ 天然气是一种常见的能源,主要成分是甲烷,通常占70-90%。为了安全起见,气体公司会在天然气中添加硫醇,以便人们能够检测到气体泄漏。甲烷在空气中燃烧的火焰温度约为1960°C,在纯氧中燃烧时,温度可超过2800°C,适用于焊接等高温应用。作为一种用途广泛的能源,天然气在我们的日常生活中扮演着重要的角色,从烹饪、供暖到发电和驱动车辆,都离不开它。天然气的高效燃烧和相对清洁的特性,使其成为替代煤炭和石油的理想选择,有助于减少环境污染和应对气候变化。
Deep Dive
This chapter defines natural gas, its composition, processing, and combustion properties. It also highlights its various applications, from cooking and heating to industrial processes.
- Natural gas is primarily methane (CH4), often containing ethane, propane, butane, and other gases.
- Processing removes impurities to increase methane content for cleaner burning.
- Methane's flame temperature varies with oxygen levels, reaching high temperatures in pure oxygen.
