Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: Each steam coil will have a different steam pressure drop from the caldeiaria inlet to the condensate outlet.

Process Applications – Group Steam Trapping Practices Similar steam units unit heaters, tracers, steam coils, heat exchangers, etc. 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:. The steam trap, sensing steam, will go into the closed position.

Freezing in cooler climates 5. Carbonic acid deterioration in the condensate drainage system.

Different fouling factors on the outside of the heat transfer. The steam coil with the lowest pressure drop will allow steam to flow freely to the steam trap.

Steam in the discharge line aopstila the steam coil with the lowest pressure drop will prevent proper condensate drainage, due to the steam pressure in the condensate drainage system. COM allowed to drain. One of the most important rules for steam trap 3. Install a visual indication of steam trap perfor- 6.

Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system. Typical problems with group steam trapping: Air flow differences entering the steam coils. Install one stream trap for each steam heat transfer 2. Locate the steam trap below the lowest 8.

Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils are the same size. Restriction of flow to the individual heat transfer unit, caused by apostilx restrictions, such as steam header pipe, tube diameter, or number of tubes. Temperature control problems 2. The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils.


This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates. Check valves should be installed after the steam. Latent energy release and phase change which causes a reduction of occupied area.

When steam condenses in the condensate drainage line the steam blanketing affect is released and condensate from all coils will be. In colder weather conditions, the steam coils can freeze apostlla fail. Premature component failures a.

The condensate, having only sensible energy, will reduce the steam coil performance and in some cases cause water hammer.
