What is the steam generator manufacturer's full water running time treatment method?
When the boiler steam pressure and feed water pressure are normal, and the bucket water level exceeds 50mm, the following measures should be taken:
(1) Control and flush the two water level gauges of the steam drum to check if the indication is correct.
(2) The water supply adjustment is changed from automatic to manual, and the manual water supply door and the small total adjustment door are closed to reduce the water supply.
If the water level in the drum still rises after the above treatment, if it exceeds 75 mm, the following measures should be taken:
(1) Open the steam drum emergency drain door and close it immediately when the water level is at the normal water level.
(2) According to the steam temperature condition, close or close the desuperheating sluice, open the main steam trap and the superheater trap.
After the treated drum water level continues to rise and exceeds the water level in the upper part of the drum water level gauge, it will be shut down urgently, disassembled as soon as possible with the mother tube, immediately stop the water inlet, open the recirculation door, strengthen the release of boiler water, and pay attention to the drum water level gauge. The upper water level appears and the water level closes after the normal water level. After the standby furnace is in a normal state, the value obtained is long and can be operated according to the hot furnace.
If you do not see the water level in the drum level and do not find it in time, you should take the following measures:
(1) Compare and flush the two water level gauges of the steam drum to check if the indication is correct. Open the drum water level completely to release the sluice, then slowly close the water release door. If the water level gauge has a water level and continues to rise and fills the water level gauge, it is proven that the boiler full water does not exceed the water level gauge steam side tube and is considered an emergency shutdown.
(2) After opening the water level gauge and slowly releasing the water gate, the water level is not visible in the water level gauge. To confirm that the water is full, close the steam door, open the drain door, and immediately close the drain door after draining the water in the water level gauge. Quickly open the water level in the microvalve water level and fill it with water. At this point, it can be determined that the water level exceeds the steam side water pipe of the drum water level gauge and should be removed as soon as possible according to the emergency shutdown treatment.
(3) When the water level accident occurs in the boiler, if it is difficult to determine the water level, the furnace should be stopped immediately. After stopping the furnace, call the water method to check the water level of the drum.
