城镇化过程中天然气分布式能源发展机遇探讨

城镇化势必会带来大规模的能源需求,如何处理好需求与供给的矛盾对于社会稳定及城镇可持续发展至关重要。本文从城镇化进程中居民建筑能耗角度进行分析,提出能源梯级利用对于节能的重要性;首先对中国2020年、2030年以及2050年的居民建筑能源需求进行了初步预测,再分别对比分析分供系统和天然气分布式冷热电联供系统在满足不同年份能源需求时的一次能源供应量;结果表明,天然气分布式系统较分供系统可节约40%能耗,对于缓解城镇化与能源供需矛盾具有重要作用。

Investigation on Development Opportunities of Natural Gas Distribution Energy in the Process of Urbanization

Urbanization would bring a large-scale of energy requirements, and dealing well with the contradiction between demand and supply is of significance for social stability and urban sustainable development. This paper focused on the residential building energy consumption in the process of urbanization, and put forward the importance of graded energy utilizing to energy saving. Firstly, the demands of China residential building energy consumption in the year of 2020, 2030 and 2050 were initially estimated, and then the amount of primary energy supply of the distributed supply system and natural gas distributed combined cooling heating and power （CCHP） system were comparatively analyzed respectively in different years, which meet the total energy requirements. The results shows that the natural gas distributed system could save 40% of energy consumption compared with distributed supply system, indicating the natural gas distributed system plays an impor- tant role in to ease the contradiction between energy supply and demand in the urbanization.
