在600MW火电机组中,手动调节方式是恒定再热器汽温和锅炉用水量的重要操作手段,也是减温水自动调节系统的必要补充。如何实现减温水的最佳调节,关系到锅炉运行的安全性和经济性,通过对手动调节减温水的不同操作方法进行比较和大量观察数据的分析归纳,找出锅炉负荷与减温水量及温控与调整阀开度的量化关系,总结出具有可操作性的减温水手动调节工艺,应用在日常操作中既简化了操作程序又达到了机组稳定运行的要求,有一定参考价值。 In the 600MW thermal power unit, the manual adjustment mode is an important operation means of the constant reheater steam temperature and the boiler water consumption, and is also a necessary supplement to the automatic regulating system of the water for reducing the temperature. How to achieve the best adjustment of the water temperature reduction is related to the safety and economy of the boiler operation. Through the comparison and analysis of different operation methods of manually adjusting the water temperature reduction, we can find out the boiler load, Control and valve opening to quantify the relationship between summed up the manual operation of the adjustable water temperature control technology used in daily operations not only simplifies the operation procedures and achieve the stable operation of the unit requirements, have some reference value.
