| Water hammer |
| |
Potentially damaging condition in steam pipes where waves develop on the condensate surface within a pipe as steam rushes over it. If the peak of the wave becomes high enough to reach the roof of the pipe, the water in the wave is pushed violently to the far end of the pipe.

| Waterlogged |
| |
Condition of steam coils where condensate is not discharged at a sufficient rate to keep it from accumulating in the coil. Filled with condensate, the coils do not transfer significant heat to the kiln.
