摘　　要：随着火电机组不断发展,超临界、超超临界锅炉配套的锅炉启动疏水扩容器也随之产生。通过理论计算设置合理的结构,设计一个多级节流孔管装置对高压流体进行降压,使得高压力的流体降至一个扩容器可以接受的压力后进行闪蒸排放,防止设备瞬间超压,产生不安全因素。With the continuous development of thermal power the Boiler Drain Flash Vessel for su- percritical and ultra supercritical boiler were also invented. Design a multi - stage decompression de- vice to reduce the pressure of high - pressure fluid by theoretical calculations and proper structure. Reduce the high - pressure fluid at an acceptable level to release the fluid to flash which can prevent the equipment from instantaneous overpressure and keep the equipment safe.
