燃煤机组的供热改造项目实例分析

Case Analysis of Heating Reconstruction Project of Coal Fired Unit

[目的]为了提高燃煤机组的运行效率和经济效益,以珠海发电厂的供热改造项目为对象进行实例分析,探索煤电机组经营困境的破局之路。[方法]通过剖析珠海发电厂供热改造项目,从可行性、控制策略、改造效果等几个方面综合探讨。[结果]分析结果表明,供热改造后机组煤耗明显降低,同时供热量的增加提高热电比,可争取更多的计划电量,增加发电基数。[结论]供热改造对于条件合适的燃煤机组是一个值得参考的优化途径,具有非常重要的指导意义和经济价值。

[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.
