摘要：在这个电气时代，电力是必不可少的生活必备元素。火力发电作为最传统同时也是最有效的发电方式方法之一。除氧器作为火力发电装置火力发电过程中反应最先开始的设备；蒸汽除氧作为火力发电最先开始的步骤。除氧器以及除氧过程绝对是火力发电过程中最为关键也最为重要的环节之一。使用除氧器的唯一目的是通过加热锅炉给水，使溶于水中的氧气及杂气不再被水溶解，这样可以保护加热炉炉体及汽包免收溶解于水的氧气的腐蚀。保护了锅炉的炉体等于避免了造成巨大的经济损失，所以，控制除氧器的除氧工程是具有十分重要且有价值的现实经济意义。

除氧器控制系统毕业论文、设计、项目讨论和研究设计，采用组态软件、PLC控制器的连接，以工业组态软件为平台的整个应用除氧器控制系统设计，对除氧器的总体控制的实现。对除氧器内的液位、出口流量以及压力进行控制,这样才能够尽最大能力的去管制除氧器的热力除氧过程。71091

Deaerator Control System Design

Abstract: In this age of electricity, electricity is an essential element of life. Thermal power generation is one of the most traditional and effective methods of power generation. Deaerator as a thermal power plant, thermal power generation process of the first reaction of the equipment; steam deaeration as the first step in thermal power generation. Deaerator and deoxidization process is absolutely one of the most important and important links in the process of thermal power generation. The only purpose of using the deaerator is to heat the boiler feed water, so that the oxygen and impurity gas dissolved in the water are no longer dissolved by water, thus protecting the heating furnace, the furnace body and the drum from the corrosion of oxygen dissolved in water. To protect the boiler's furnace body is to avoid huge economic losses, therefore, it is of important and valuable practical economic significance to control the deaeration of the deaerator.

Deaerator control system, graduation thesis design, project discussion and research design, using the connection configuration software, PLC controller, design platform for the whole application of Deaerator Control System Based on industrial configuration software, to achieve the overall control of deaerator. Control the level, outlet flow and pressure of the deaerator so that the thermal deaeration process of the deaerator can be controlled as much as possible.
