摘　　要：燃煤发电原理是通过热能将水加热转换为蒸汽,利用蒸汽的动力冲转汽轮机,再由汽轮机带动发电机发电,最终实现能量的转换。在整个水汽循环过程中,水汽高温高压在各种管道中流动,对水质的要求很高,其中重要的一个参数就是SiO_(2)的含量。一旦SiO_(2)含量超标将造成管道、凝汽器、汽轮机叶片等重要设备腐蚀、结垢,轻则影响发电效率,重则引发爆管等恶性事故。因此,在线硅表的维护显得尤为重要。在保证在线硅表准确的前提下,探索自配试剂配方,逐步替代进口试剂,利用头脑风暴法选限最优方案,并将措施进一步细化,实施效果显著,全年可节约10万元生产费用,达到了节能降耗的目的。The principle of coal-fired power generation is to convert water heating into steam through thermal energy,use the power of steam to impulse the turbine,and then the turbine drives the generator to generate electricity,and finally realize the conversion of energy.In the whole process of water vapor cycle,water vapor high temperature and high pressure flow in various pipes,the requirements of water quality is very high,one of the important parameters is the content of SiO_(2).Once the SiO_(2) content exceeds the standard will cause corrosion and scaling of important equipment such as pipes,condensers,turbine blades,etc.,which will affect the power generation efficiency in light cases and cause malicious accidents such as pipe bursts in heavy cases.Therefore,the maintenance of the online silicon meter is particularly important.Under the premise of ensuring the accuracy of the online silicon meter,we explore the formulation of self-formulated reagents,gradually replace the imported reagents,use the brainstorming method to select the optimal solution,and further refine the measures,the implementation of significant results,the annual savings of 100,000 yuan of production costs,to achieve the purpose of energy saving and consumption reduction.
