Boiler deaerator
Thread Content
Automatic control of the steam flow rate injected at the top of a boiler deaerator, with a installed steam injection nozzle injecting steam into the feedwater. The steam flow rate is regulated based on the actual temperature of the water in the tank, thereby preventing steam shock, especially during tank heating. Therefore, the maximum opening degree of the injection valve is calculated based on the difference between the actual temperature and the saturation temperature. What does preventing steam shock mean in that context? ? Please. .
It should be bubbles that form when there is an excessive amount of steam that cannot be absorbed by the water in time; this leads to a sharp rise in water level, resulting in an artificial water level reading. Called a shock wave – it’s confusing.
