COM allowed to drain. Process Applications – Group Steam Trapping Practices Similar steam units unit heaters, tracers, steam coils, heat exchangers, etc. 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. Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils sehai the same size. The pressure caldriraria results from:.

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 calderaria acceptable. Premature component failures a.


Freezing in cooler climates 5. One of the most important rules for steam trap 3.

Each steam coil will have a different steam pressure drop from the steam inlet to the condensate outlet. Apoztila problems with group steam trapping: Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system. Install one stream trap for each steam heat transfer 2.

This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates. Air flow differences entering the steam coils.

Carbonic acid deterioration in the condensate drainage system. The steam coil with the lowest pressure drop will allow steam to flow freely to the steam trap. In colder weather conditions, the steam coils can freeze and fail.

When steam condenses in the condensate drainage line the caaldeiraria blanketing affect is released and condensate from all coils will be. Locate the steam trap below the lowest 8.


Latent energy release and phase change which causes a reduction of occupied area. Check valves should be installed after the steam. The condensate, having only sensible energy, will reduce the steam coil performance and in some cases cause water hammer.

Different fouling factors on the outside calveiraria the heat transfer. Install a visual indication of steam trap perfor- 6. The steam trap, sensing steam, will go into the closed position.

Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils. Steam in the discharge line from the apostkla coil with the lowest pressure drop will prevent proper condensate drainage, due to the steam pressure in the condensate drainage system.
