What is one potential issue with using a float steam trap in a system?

Using a float steam trap in a system can indeed be problematic when it comes to handling dirty condensate. The float steam trap relies on a buoyant float to control the discharge of condensate from the steam system. If the condensate contains debris or sediment, it can impede the movement of the float, leading to improper operation. This can cause the trap to either fail to open or fail to close, resulting in steam loss or water hammer conditions.

The other options suggest issues that may not specifically relate to float steam traps or are more accurately addressed by other types of traps. For example, some traps may have specific pressure limitations or cost factors, but the primary concern for float steam traps is their sensitivity to the quality of the condensate they are processing. This highlights the importance of ensuring that the steam system is maintained and that the condensate is kept clean to ensure efficient operation of float steam traps.
