全中水条件下循环水模拟试验研究及应用

Experimental study and application of circulating water simulation test fully replenished by intermediate water

华电滕州新源热电有限公司2台350 MW机组通过开展全中水方式的循环水补水模拟试验,确定了满足机组安全、经济运行的水质控制标准及加药量,同时进行了现场实际应用,循环水系统无结垢和明显腐蚀,实现了高比例中水回用条件下机组的安全、稳定运行。

2 × 350 MW units of Huadian Tengzhou Xinyuan Thermal Power Company Limited carried out a simulation test on circulating water fully replenished by intermediate water. The dosages that met the water quality control standards required by safety and economic operation of the unit were determined. The field tests were made,whose results showed that the circulating water system had no scale or obvious corrosion. The safe and stable operation of the unit with high proportion of reused intermediate water was realized.
