Abstract:
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.
Key words:
