Introduction In order to improve the operation efficiency and the economic benefits of coal-fired units， this paper takes the heating reconstruction project of Zhuhai Power Plant as an example to explore the way which can break the operating predicament of coal-fired power unit.
Method By analyzing the heating reconstruction project of Zhuhai Power Plant， this paper conducted a comprehensive discussion on the feasibility， control strategy and construction effect of this project.
Result The analysis results showed that the coal consumption of the unit was significantly reduced after the heating reconstruction， and the increase of heat supply increased the heat power ratio， which can also strive for more planned electricity and the power generation base value.
Conclusion Heating reconstruction is a valuable optimization way for coal-fired unit with suitable conditions， which has very important guiding significance and economic value.
