中国气体燃料资源及开发利用前景展望

在经济发展迅猛、能源紧缺、环境恶化等因素的共同驱动下,中国对气体燃料发动机的需求非常紧迫。为此,分析了中国常规天然气、煤层气、垃圾填埋气、页岩气等轻质气体燃料的资源分布、开采及利用状况,认为大量的气体燃料资源储备为中国气体燃料发动机的发展提供了契机。然而,对我国动力行业的发展水平及规模的分析结果表明,目前我国气体燃料发动机的技术水平和制造规模都远远落后于发达国家,缺乏竞争力,满足不了国内市场的需求。进而,对气体燃料的开发利用和气体燃料发动机的发展提出以下建议:1健全煤层气利用设施,推动煤层气产业的发展;2规范市场,优化资源利用比例,提高气体燃料的利用效率;3加快对气体燃料发动机的研究,在中远期能源和动力发展规划中要高度重视我国气体燃料发动机核心关键技术和制造水平的迅速提高;4针对不同的气体燃料,优化气体燃料发动机的性能。

Prospects of gas fuels resources and their exploitation and utilization in China

〗Under the present situation of rapid economic development, energy shortage, environment deterioration, etc., gas fuelled engines will be urgently needed in China. In view of this, through an overview of the light gas fuels such as conventional natural gas, CBM, landfill gas, shale gas, etc., as well as their distribution, exploitation and utilization status, we concluded that a large amount of gas fuels reserves provide an opportunity for the development of gas fuelled engines in China. However, the present technical level and manufacturing scale of gas fuelled engines are still lagging far behind those developed countries. We presented the following proposals for China to explore more uses of gas fuels and well develop gas fuelled engines. (1) CBM utilization policies and infrastructures should be implemented and fulfilled to stimulate the development of CBM industry. (2) The utilization efficiency of gas fuels should be highly improved by regulating the market and optimizing the resource utilization ratio. (3) The research of gas fuelled engines should be speeded up with focus on improving the core technologies and manufacturing level especially in the mid and long term energy and power development strategies. (4) The performance of different engines should be enhanced upon various types of gas fuels.
