摘要
当前,天然气净化厂供热系统高度依赖化石能源。为提高电气化率,提出了“市电”和“绿电与市电互补(简称绿电)”等2种绿色供热系统,利用电加热和熔盐储热技术,实现供热系统的电能替代,并对不同方案的技术、环保和经济性进行了对比分析。此外,针对绿电供热系统的容量配置开展了优化研究。研究结果表明:相较于原供热系统,市电和绿电供热系统的单位产品能耗下降,全厂电气化率上升。在绿电供热系统中,提高环保性能表现的关键在于增加系统中的绿电发电占比;而在经济性方面,为实现供热成本最低,建议只配置光伏发电装置。
Currently,the heating system of natural gas purification plants is highly dependent on fossil fuels.In order to improve the electrification rate,the paper proposes such two green heating systems as mains power and green power complementary to mains power(referred to as green power),uses electric heating and molten salt thermal storage technology to achieve electricity substitution in the heating system,and comparatively analyzes the technical,environmental,and economic performances of different schemes.In addition,it conducts the optimization research on the capacity configuration of green electric heating systems.The research results show that the unit product energy consumptions of two systems decrease and the electrification rate of the overall plant increases compared to the original heating system,the key to improving environmental performance in green power heating systems is to increase the proportion of green power generation in the system,and it is recommended to only install photovoltaic power generation devices to achieve the lowest heating cost in terms of economic performance.
