摘　　要：从理论上研究了超音速汽液两相流升压加热器的出口流量调节方法 ,在此基础上设计和建立了由 4台汽液两相流升压加热器及再循环管并联组成的除盐水加热系统 ,该系统可以在 (6 0～ 36 0 )t/h的出口流量范围内将除盐水加热到给定温度 ,并具有升压能力。实际运行试验表明 ,该系统运行稳定、可靠 。The method of regulating the outlet flow rate of the boosting heater with supersonic speed steam-liquid two-phase flow has theoritically been studied, and a desalinated water heating system composed of four boosting heaters and a recirculating pipeline has been designed and built based on the said study. The said system can heat up the desalinated water to a given temperature while the outlet flow rate changing from 60t/h to 360t/h, and having boosting capability. practical operation test shows that the operation of the said system is stable and reliable, satisfying completely the requirements of production process in thermal power plants.
