| Abstract: | The reasons for the overpressure of drain water flashtank and failure to recover drain water in 600 MW supercritical unit of Huaneng Shantou Power Station were analyzed.Based on this,the solution was proposed to discharge the drain water from boiler steam-water separator to condenser throat through three-stage desuperheater.The unit operation and solution application after retrofitting was evaluated. |
