“提高煤气质量。提出各种燃气达到国家气质标准或更高标准的分期目标”。 在我国幅员辽阔,能源分布不均,各地能源结构不一和交通运输尚在逐步开畅的情况下,我国城市煤气采取“因地制宜、多种气源、多种途径的发展方针”是完全正确的。因此当前我国城市燃气有:天燃气、液化石油气、人工煤气、工业余气、矿井气等各种燃气。 “Improve the quality of gas. Propose the phased goals for various gas gases to meet national temperament standards or higher standards.” As China has a vast territory, uneven energy distribution, different energy structures in different parts of the country, and the gradual opening of transportation, it is absolutely right for China’s city gas to adopt a policy of “according to local conditions, multiple sources of gas, and multiple approaches to development”. . Therefore, currently China’s urban gas is: natural gas, liquefied petroleum gas, artificial gas, industrial surplus gas, mine gas and other gas.
