科学用能与分布式能源系统

从对能源的中长期需求和能源供应能力的缺口出发,论证了节能和科学用能应当是我国能源发展战略的核心。阐述了科学用能的研究内容、方法和主要特点,指出应重点抓住高耗能产业和科学用能的共性科技问题。对建筑科学节能,提出尽可能采用可再生能源和环境能源以节约化石能源和电能。分布式能源系统是科学用能的范例,它与集中式发电的有机结合是新世纪电力工业和能源工业的重要发展方向。开发小型和微型燃气轮机可以提升我国动力工业的技术水平;正确确定冷热电三者的关系,充分发挥中低温余热的作用,是使分布式能源系统获得最大节能效果和最大经济效益的关键。

Using Energy Scientifically and Distributed Energy System

From the standpoint of a middle-& long-term demand for energy supply, it is demonstratedthat the energy conservation or using energy scientifically should be a core of China’s energy strategy. Themain contents, methods and features of scientific utility of energy are discussed. For energy saving inarchitecture, it should make all possible to use renewable energy and environment friendly energy. The dis-tributed energy system is an example of using energy in a scientific manner, which should make greatlyprogress in China. The development of small and micro turbines will improve the technical level of nationalpower industry. The right choice of relation among the electricity, cooling, and heating is of significance forincreasing the effects of energy conservation and getting the good economic benefits.
