Regarding the selection of displacement for steam traps
Thread Content
If the displacement of the selected steam trap is much larger than the displacement required by the process, will this affect the operation of the steam trap? Thank you
Generally, the drainage capacity of a steam trap should have an appropriate safety factor. If your process requires a drainage capacity of 300 KG/H, then it is advisable to choose a steam trap with a drainage capacity of 900 KG/H, resulting in a safety factor of 3:1. This safety factor can range from 2:1 to 10:1; however, too high a value comes with various drawbacks, such as increased installation and purchase costs, faster wear and tear, greater steam losses, and higher pressure in the backpressure system.
If the selection is at a ratio higher than the appropriate one, the steam trap will release some steam when it operates; as a result, its operating frequency increases, which affects its lifespan
What would happen if, on the other hand, the selected desiccant is of lower quality than what is required by the system design? Could this lead to pressure buildup of steam in the system?
Reply to 6# jsdywzr: If the selected hydroscoper does not meet the requirements specified in the system design, it will result in poor heat exchange efficiency within the system, thereby affecting the increase in the system’s capacity； Second, it can lead to poor drainage of condensate, causing water hammer that damages equipment and pipelines.
Generally, the safety factor is usually set between 2.0 and 3.0, but it still depends on what the supplier recommends. In the case of TLV, a safety factor of 1.5 times is usually sufficient. Finally, when choosing a demister, there are other factors to consider... for example, whether you intend to recycle the condensed water for reuse in the process, as too high a pressure loss can affect the volume of liquid that can be discharged
