摘　　要：600 MW亚临界汽包炉炉水的处理方式影响机组的蒸汽品质,优化炉水处理工艺对于提高锅炉蒸汽品质、预防汽轮机积盐具有重要作用。通过试验定量考察了数台同型号600 MW亚临界汽包炉炉水磷酸盐含量对蒸汽品质的影响,确定了各机组最优的炉水处理工艺及炉水水质监控指标最优控制方案。The boiler-water treatment method of 600 MW sub-critical boiler unit has direct influence on its steam quality. It is important to optimize the boiler-water treatment method in order to improve boiler steam quality and prevent salt deposits on steam turbine. Based on experiments, the effect of phosphate concentration in the boiler water of several 600 MW sub-critical boilers of the same type on steam quality has been investigated quantitatively. The optimal boiler-water treatment process of every unit and corresponding boiler-water quality controlling scheme are determined.
