Steam generator Generally, they operate for a long time. After the installation and use of the steam generator for a long time, some problems will inevitably occur in some aspects of the boiler, so we need to maintain the boiler equipment. So, if in daily use, large-scale gas and steam boiler equipment suddenly has some serious fault problems, how should we carry out emergency shutdown of boiler equipment? Now let me briefly explain the relevant knowledge for you.
Before we understand these contents, we need to know under what circumstances we should Steam generator equipment Carry out emergency shutdown measures.
When we find that the water level of the equipment is lower than the visible edge of the lower part of the water level gauge, when we increase water supply and other measures, but the water level continues to decline, the equipment water level exceeds the visible high water level, the water level cannot be seen after the drainage, the water supply pump is completely faulty or the water supply system is faulty, and water cannot be supplied to the boiler, all the water level gauges fail, and equipment components are damaged, endangering the safety of the operators The damage of combustion equipment, collapse of furnace wall or burning of equipment frame threaten the normal operation of equipment, as well as other abnormal conditions that endanger the normal operation of steam generator.
In case of these situations, we should timely adopt the emergency shutdown operation procedure: immediately follow the command to supply fuel and air, reduce the induced air, then quickly close the outlet main steam valve, open the exhaust valve, and reduce the steam pressure.
In the above operation process, it is generally not necessary to supply water to the equipment, especially in the case of emergency shutdown due to water shortage or full water, it is strictly prohibited to supply water to the boiler to prevent the sudden change of temperature and pressure in the boiler from expanding the accident or a large amount of steam carrying water causing pipe water hammer. Precautions for emergency shutdown operation: the purpose of emergency shutdown operation is to prevent the accident from further expanding and reduce accident losses and hazards to a large extent. Therefore, during emergency shutdown operation, keep calm, find out the cause first, and then take measures against the direct cause. The above are only general operation steps, and special cases should be handled according to the strain.
The above is what Xiaobian brought to you about the large-scale Gas steam generator equipment Under what circumstances should the emergency shutdown be carried out and the method of shutdown.
