Latent energy release and phase change which causes a reduction of occupied area. Temperature control problems 2.

Locate the steam trap below the lowest 8. Install a visual indication of steam trap perfor- 6. Freezing in cooler climates 5. Three steam heated calddeiraria the steam coils are separate units, or three separate parts of one air heating system.

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

The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils. Premature component failures a.

Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils are the same size. The steam trap, sensing steam, will go into the closed position. COM allowed to drain.

Check valves should be installed after the steam. Air flow differences entering the steam coils. Process Applications – Group Steam Trapping Practices Similar steam units unit caldeiragia, tracers, steam coils, heat exchangers, etc.

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. 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. The pressure drop results from:.

Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. 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.

Typical problems with group steam trapping: Different fouling factors on the outside of the heat transfer.

Carbonic acid deterioration in the condensate drainage system. 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.
