我国火力发电能耗状况研究及展望

Research and Prospects of Energy Consumption of Thermal Power Generation in China

通过近十多年的发展,高效能、大容量发电机组逐步取代低效率、小容量的发电机组,我国火力发电的煤耗率呈现逐年下降趋势。但是火力发电依然是耗能大户,挖掘火力发电的潜在节能点,对于满足"十二五"关于节能减排的要求有重要作用。文章分析了我国近10年来火力发电煤耗率的变化趋势,并与部分发达国家进行对比。随着技术的不断创新和管理的到位,我国火电能耗水平将进一步降低,预计到2020年,我国火电供电煤耗率有望降低到300 g/kW·h以下。

Through nearly 10 years development,coal consumption rate of thermal power generation presents a declining trend with high-performance,large-capacity generator set gradually replacing the inefficient,small capacity generator set.But thermal power generation is still a major energy using industry.Exploring energy saving potential points has an important role for meeting the twelfth five year plan on energy saving requirements.In this paper,coal consumption rate change of thermal power generation during the past 10 years is analyzed and compared with some developed countries.With the development of technology innovation and management,energy consumption of thermal power generation will be further reduced and coal consumption rate is expected to be reduced to less than 300 g/kW·h by 2020.
