The pressure drop results from:. Air flow differences entering the steam coils. Temperature control problems 2.

Premature component failures a. Typical problems with group steam trapping: Each steam coil will have a different steam pressure drop apostlla the steam inlet to the condensate outlet.

Freezing in cooler climates 5. 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.

Latent energy release and phase change which causes a reduction of occupied area. Locate the steam trap below the lowest 8. The steam trap, sensing steam, will go into the closed caldeiradia. Process Applications – Group Steam Trapping Practices Similar steam units unit heaters, tracers, steam coils, heat exchangers, etc.

Check valves should be installed after the steam. Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. Install a visual indication of steam trap perfor- 6. The condensate, having only sensible energy, caldeirxria reduce the steam coil performance and in some cases cause water hammer.

Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: 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 same size.

In colder weather conditions, the steam coils can freeze and fail. 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. COM allowed to drain.


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 calceiraria condensate drainage system.

Different fouling factors on the outside of the heat transfer.

The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils. When steam condenses in the condensate drainage line the steam blanketing affect is released and condensate from all coils will be.

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. One of the most important rules for steam trap 3.
