发电厂入炉煤质变化经济性分析

Economy Analysis on the Quality Variation of the As-fired Coal in Power Plants

依据规程对670 t/h锅炉及1025 t/h锅炉系统运行状况进行调查,对锅炉本体、辅机能耗、煤耗进行测试分析,以评价不同煤质情况下设备、系统主要技术经济指标,定性、定量分析煤种变化对系统安全、稳定运行及其能耗的影响;认为提高机组经济性潜力较大,并提出改进建议。

based on the code to investigate the operation states of the 670t/h and 1025t/h boilers system,testing and analyzing the energy/coal consumption of the boiler body and the auxiliaries,for evaluating the tech-economic index of the equipments and systems under the different coal properties,the influences on the safety and stability in system operation and energy consumption due to the change of coal variety were analyzed quantitatively and qualitatively,it was shown that there were a big potential in enhancin...
