达州高低压给水加热器

高压给水加热器是利用来自汽轮机的抽汽，来加热锅炉给水，使给水达到所要求的温度，从而提高电厂的热效率和保证机组的出力。

       低压给水加热器是利用汽轮机的低压抽汽加热由凝结泵来的低压给水，使给水达到所要求的温度，从而提高电厂的热经济性，我公司根据用户的不同要求，采用不同的设计方案，选择汽、水流速，传热好、汽阻小，进行振动计算、支座的地震计算、管座的推力和推力矩计算。我公司设计的低压加热器有立式顺U型管、直管等类型，针对不同需要，换热管可采用铜管、钢管、不锈钢管等。采用可靠的安全保护系统，每台低压给水加热器均附有水位显示器、调节和报警装置，疏水水位自动调节，高水位时迅速报警以切除本台低压加热器。在管侧和壳侧均有安全阀以防超压。山东宏达科技集团有限公司（济南板式换热器）是一家集新能源产品、核级压力容器产品、石油石化产品、环保工程设计、制造及产业项目综合性承包安装为一体的集团化公司。

  High pressure supply water heater uses discharge steam from steam turbine to heat supply water of boiler, and makes supply water to reach required temperature so as to improve thermal efficiency of power plant and to ensure output of the unit.
  Low pressure supply water heater uses low pressure discharge steam from steam turbine to heat low pressure supply water of condensation pump, makes supply water reach required temperature so as to improve thermal economic performance of power plan. Our company uses different design plans according to different requirements of users, selects optimal steam and water flow speeds, ensures good heat transfer and small steam resistance, and makes vibration calculation, earthquake calculation of base, thrust and thrust torque calculation of pipe seat. Low pressure heat exchangers designed by our company include various types such as vertical smooth U shape pipe and straight pipe. According to different needs, heat exchange pipes can use copper pipe, steel pipe and stainless steel pipe, etc. Reliable safety protective system is used, each low pressure supply water heater has water level indicator, adjustment device and warning device, discharge water level is adjusted automatically, warning is given out at high water level so as to turn off the low pressure heater. Safety valves are set on pipe side and casing side so as to prevent overpressure.
