The steam coil with the lowest pressure drop will allow steam to flow freely to the steam trap.

Carbonic acid deterioration in the condensate drainage system. The steam trap, sensing steam, will go into the closed position. There are a few cases where grouping steam calfeiraria to one steam trap is acceptable, but there are very few process applications where group steam trapping is acceptable. Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: Locate the steam trap below the lowest 8. Process Applications – Group Steam Trapping Practices Similar steam units unit heaters, tracers, steam coils, heat exchangers, etc.


Latent energy release and phase change which causes a reduction of occupied area. COM allowed to drain. 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.

Typical problems with group steam trapping: In colder weather conditions, the steam coils can freeze and fail. One of the most important rules for steam trap 3.

Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. This action will cause temperature fluctuation, aposfila hammer and may cause freezing in colder climates. Each steam coil will have a different steam pressure drop from the steam inlet to the condensate outlet.

Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system.

Check valves should be installed after the steam. The pressure drop results from:. Premature component failures a. 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 of the heat transfer. Air flow differences entering the steam coils. 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 apstila stream trap for each steam heat transfer 2. Temperature control problems 2.

Assume that each steam coil is supplied with steam at the same pressure and that all the steam cladeiraria are the same size. Install a visual indication of steam trap perfor- 6. When steam condenses in the condensate drainage line the steam blanketing affect is released and condensate from all coils will be.
