Immediately stop the boiler sewage, stop the boiler soot blower desulfurization soot blowing, close the oxygen discharge door of the deaerator to prevent the deaerator, the condenser water level falling rapidly. Immediately close the low-pressure auxiliary steam to the heat exchange station and calcium carbide plant steam supply door, if necessary, directly out of the low auxiliary. Close all pressurized and no ah sparse water door. Immediately close the condenser make-up water regulating door and electric door to prevent the unit vacuum from dropping. According to the water level change of deaerator and condenser, control the water level of deaerator appropriately, ensure the high water level of condenser, reduce the load appropriately, and prevent the loss of steam and water. Closely monitor the water level of the closed water tank, send someone to the closed water tank in place to make up water cut to condensate, pay attention to the closed water temperature.

When the demineralized water system returns to normal, it will return to the original operating state. If the demineralized water system can not be restored in time and affect the safe operation of the unit to apply for shutdown, to prevent the expansion of the accident.
