避免机组骤升负荷进程中除氧效果的恶化，能够经过投入加装在给水箱内的再欢腾管（补充的加热蒸汽管）或内置式加热器来处理。
to avoid the deterioration of the deoxidization effect during the sudden load process of the unit, it can be treated by the reloaded rejoicing tube (supplemented heating steam pipe) or built-in heater in the water tank.
汽轮机负荷变化时，除氧器滑压运转对给水泵人口汽化的影响。当汽轮机负荷添加时，除氧器内作业压力升高，此刻给水温度是低于新压力下的饱满温度，给水泵进口不可能发生汽化，对给水泵的运转变得更安全些，这是有利的。
the influence of the sliding pressure operation of deaerator on the population vaporization of the feed pump is changed when the steam turbine load changes. when the steam turbine load is added, the operation pressure in the deaerator increases, and the water supply temperature is lower than the full temperature under the new pressure at the moment. it is not possible to vaporize the inlet of the pump, and it will be more safe to operate the water supply pump.
在汽轮机负荷俄然减小时，除氧器内作业蒸汽压力随之下降。此刻泵进口水温因静压头的效果短时间内不能下降，但泵进口的压力却随除氧器的压力下降而下降了，所以呈现了泵进口压力和水温不匹配，形成泵运转安全可靠性下降，汽化危险剧增的局面。
the steam pressure in the deaerator decreases as the load of the turbine decreases. at the moment, the inlet water temperature of the pump can not be reduced for a short time due to the effect of the static pressure head, but the pressure of the inlet of the pump drops with the deoxidizer pressure. therefore, the pump inlet pressure and the water temperature are not matched, and the safety and reliability of the pump operation is decreased and the vaporization danger is increasing dramatically.
汽轮机骤降负荷的暂态进程中避免给水泵汽化的问题，需经过对滑压除氧器的热力体系进行暂态工况的核算，选择适宜的给水箱容量，安置高度和泵吸入管的管径，以及其他一系列必要的办法来防止，选择进程还需进行必定的技术经济比较。
in the transient process of the sudden drop of the steam turbine, the problem of avoiding the vaporization of the water pump is avoided. it is necessary to check the transient condition of the thermal system of the deaerator, select the appropriate capacity of the water tank, the height of the pump and the pipe diameter of the pump, and other necessary measures to prevent the process. technical and economic comparison.
