摘　　要：通过对磷酸盐隐藏现象的分析，结合12．5MPa汽包炉水自身情况，改进协调磷酸盐-pH处理，将炉水磷酸盐含量控制在2-4mg／L，pH值控制在9．0—9．4，有效避免磷酸盐隐藏现象的发生。Through the analysis of the phenomenon of phosphate hide, also in consideration of me conditions of 12.5 MPa steam drum boiler water, the coordination of phosphate-pH treatment has been improved. Phosphate concentration in the boiler water was controlled between 2-4 rag/L, pH value between 9.0 -9.4. Phosphate hide was effectively avoided.
