燃煤电厂煤场场损预测研究

Study on Prediction of Coal Yard Loss in Coal-fired Power Plant

燃煤在储存过程中,由于受到外部环境因素和自身特性的影响,会发生煤量流失、水分增加、发热量降低、燃煤自燃等一系列变化。这些变化都是造成燃煤煤质、煤量损耗的重要因素,也直接关系到电厂的生产经营效益。因此,做好燃煤煤量、煤质损耗分析,认真执行损耗控制措施,以降低燃煤煤量和煤质的损耗,是火电厂煤场管理工作主要课题。

During the storage ofcoal,due to the influenceofexternal environmentalfactors and its own characteristics,a seriesof changes will occur,such as coal loss,water increase,calorific value decrease and coal spontaneous combustion.These changes are all important factors that cause the loss of coal quality and quantity,and are also directly related to the production and operation benefits of power plants.Therefore,it is the main task of coalyard management in thermal power plants to do a goodjob of analyzing the loss of coal quantity and quality,and earnestly implement the loss control measures to reduce the loss of coal quantity and quality.
