Introduce the respective solutions to two flooding accidents in oil and gas boilers

　　During the operation of oil and gas boilers, the water level has always been the main concern, because once the boiler water level is higher than the safe water level, the normal operation of the equipment will be endangered. This phenomenon is also called a flood accident. Generally, flooding accidents can be divided into two situations, one is slight flooding, and the other is severe flooding. The corresponding treatment methods are also different.

　　When the boiler is full of water, the first thing to do is to flush the water level gauge to check if there is a false water level, and to confirm whether it is slightly full or severely full. Only after clearly distinguishing this basic nature can targeted solutions be taken.

　　If the boiler is only slightly filled with water, the incineration should be weakened accordingly, and the feedwater automatic regulator should be set to manual operation; at the same time, some of the feedwater valves should be closed to weaken or stop the feedwater; and then the recirculation pipe of the oil and gas boiler economizer should be opened. Valve or bypass flue.

　　In addition, the drain valve must be opened to release part of the pot water; the steam pipe and the drain valve on the superheater should be opened. The purpose of this is to accelerate the draining. After the water level in the boiler drops to the normal water level, normal operation can be resumed.

　　If the flooding accident in the boiler is serious, stop the boiler in time and stop the water supply; and quickly drain the water to speed up the drainage. After the water level returns to normal, the pipes, valves and other components can be inspected and used to make the boiler work normally. .
