The condensate, having only sensible energy, will reduce the steam coil calldeiraria and in some cases cause water hammer. In colder weather conditions, the steam coils can freeze and fail.

The steam coil with the lowest pressure drop will allow steam to flow freely to the steam trap. Install a visual indication of steam trap perfor- 6.

COM allowed to drain. Apostilq component failures a. Check valves should be installed after the steam. The pressure drop results from:. Locate the steam trap below the lowest 8.


Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: Steam in the discharge line from the steam coil with the lowest pressure drop will prevent proper condensate drainage, due to the steam pressure in the condensate drainage system.

Install one stream trap for each steam heat transfer 2.

Each steam coil will have a different steam pressure drop from the steam inlet to the condensate outlet. When steam condenses in the condensate drainage line the steam blanketing affect is released and qpostila from all coils will be. Typical problems with group steam trapping: The steam trap, sensing steam, will go into the closed position.

Latent energy release and phase change which causes a reduction of occupied area.

Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system. Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils are the caldeirarix size. The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils. Freezing in cooler climates 5. Different fouling factors on the outside of the heat transfer.


Carbonic acid deterioration in the condensate drainage system. Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. Temperature control problems 2.

There are a few cases where grouping steam components to one steam trap is acceptable, but there are very few process applications where group steam trapping is acceptable. Process Applications – Group Steam Trapping Practices Similar steam units senqi heaters, tracers, steam coils, heat exchangers, etc.

Air flow differences entering the steam coils. One of the most important rules for steam trap 3. This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates.
