一、引言从节约能源,提高能源利用率的角度出发,应该合理利用不同能级的热能。对于有较大的且较为稳定的用热负荷厂家,建立热电联产系统是一项行之有效的节能措施。随着工农业生产的迅速发展,我国能源供应紧张的状态在较长的一段时间内是无法得以缓解。目前,在那些能源短缺而用电用热量又很大的地区和厂矿,为了更好地利用现有的能源资源,提高能源利用率,正在积极筹建热电联产系统。这样,一方面能提高能源利用率,节约大量的能源;另一方面能缓解该地区或该厂矿用电紧张的局面,促进生产的发展,同时还能减轻大气污染,净化环境。因此,建设热电联产系统具有一举三得之利。
I. INTRODUCTION From the perspective of energy conservation and improving energy efficiency, it is necessary to rationally utilize thermal energy of different energy levels. For larger and more stable heat load manufacturers, establishing a cogeneration system is an effective energy-saving measure. With the rapid development of industrial and agricultural production, the state of tight energy supply in China cannot be alleviated for a long period of time. At present, in regions and factories and mines where there is a shortage of energy and large amounts of electricity are used, in order to make better use of existing energy resources and improve energy efficiency, it is actively preparing for the establishment of a cogeneration system. In this way, on the one hand, energy efficiency can be improved, and a large amount of energy can be saved. On the other hand, it can alleviate the situation in the region or the mine’s power consumption, promote the development of production, and at the same time reduce air pollution and purify the environment. Therefore, the construction of a combined heat and power system has three advantages.
