摘　　要：伴随国内经济水平的快速提升,电力生产已然是重中之重的一个环节。早期生产因为技术条件不足,普遍选用参数较低、能耗较大且污染严重的燃煤系统。经过不断发展,当前国内逐步利用效率更高且污染较轻的系统取代传统燃煤机组。随着电力领域的持续前行,超临界直流锅炉也出现在实际生产之中,不同种类的锅炉设备所适用的场合有所差异,同时内部给水控制架构也不尽相同,所以在实际应用过程中始终存在不足之处。本文就针对目前超临界直流锅炉的发展进行研究,对内部控制系统存在的问题提出对应的优化方案。With the rapid improvement of domestic economic level,electric power production has become one of the most important links.Due to the lack of technical conditions in early production,coal-fired systems with low parameters,large energy consumption and serious pollution were generally selected.After continuous development,the current domestic use of higher efficiency and less pollution system to replace the traditional coal-fired units.With the continuous development of the electric power field,supercritical once through boiler also appears in the actual production.Different types of boiler equipment are suitable for different occasions,and the internal water supply control structure is also different,so there are always deficiencies in the actual application process.In this paper,the development of supercritical once through boiler is studied,and the corresponding optimization scheme is proposed for the problems existing in the internal control system.
