deaerator
Thread Content
In a thermal deaerator, high-temperature steam is injected to heat the feedwater. What does it mean to prevent the system from being affected by the impact of steam bubble explosions under conditions of low feedwater temperature and high steam injection flow rate? Please explain this in detail. // Thank you. . .
High-temperature steam used to heat feedwater can easily cause air hammers, and you will hear noises in actual production. To prevent the system from being affected by the impact of steam bubble rupture under conditions of low feedwater temperature and high steam injection flow rate, that is, to avoid the damage caused by air hammers to equipment and pipelines and reduce safety hazards.
So what exactly is going on? Does it refer to what happens when a high steam flow rate meets water at a low temperature? Or when exposed to high and low temperatures
When high-pressure steam enters cold water, its pressure drops instantly, causing the steam to vaporize and explode. A massive vibration and sound are generated at the moment of the explosion.
Thermal expansion causes a mixture of gas and liquid inside the pipeline
