摘要
随着中国电力建设技术的发展,大多数新建机组都具有高容量的超超临界机组,这些机组具有高效的循环热传导,低产煤量,节能环保等高参数。基于水将在超临界压力下转变为单向流动的事实,所以锅炉的蒸汽系统只能协助直流运行的方式进行运转。但直流炉在整体的运行工作找那个缺乏废弃物的排放,所以影响到了进入锅炉的水的品质,而水的品质又直接的影响到了轮汽机蒸汽的品质好坏,进而对机组的安全运行起到关键性的直接影响,这关系到电厂的整体经济效益,所以给水加氧技术在超超临界锅炉中放入应用对机组乃至整个电厂都有极其重要的意义。
With the development of China’s electric power construction technology, most newly-built units have high-capacity ultrasupercritical units. These units have high parameters such as efficient circulating heat conduction, low coal production, energy conservation and environmental protection. Based on the fact that water will be transformed into one-way flow under supercritical pressure, the steam system of the boiler can only assist the DC operation. However, the overall operation of the DC furnace finds the lack of waste emissions, so it affects the quality of the water entering the boiler, and the quality of the water directly affects the quality of the steam turbine, which in turn affects the safe operation of the unit. To the critical direct impact, which is related to the overall economic benefits of the power plant,the application of feedwater oxygenation technology in the ultra-supercritical boiler is of great significance to the unit and the entire power plant.
