摘　　要：总结了超高压锅炉炉水低磷酸盐处理试验结果。炉水控制PO3 -4的质量浓度为 0 .3～ 1.0mg/L ,pH值为 9.0～9.7,对金属腐蚀防护起到良好的作用 ,有利于水汽质量的提高 。The testing results about treating feedwater with low phosphate on ult ra-high pressure boilers were summarized . To keep the boiler water with a PO 3- 4concentration at 0.3～1.0 mg/L and pH values between 9.0～9.7 will play a ve ry good role in the prevention of the metal corrosion . This method can improve the quality of water and steam , reduce the scale deposit on heated surface.
