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 apostilz trapping is acceptable.

Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system. The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils. The condensate, having only sensible energy, will reduce the steam coil performance and in some cases cause water hammer. In colder weather conditions, the steam coils can freeze and fail.

Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils are the same size. Each steam coil will have a caldeiraris steam pressure drop from the steam inlet to the condensate outlet.

The pressure drop results from:. Latent energy release and phase change which causes a reduction of occupied area.

Restriction of flow to the individual heat apostia unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. Air flow differences entering the steam coils. 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. The steam trap, sensing steam, will go into caldeidaria closed position. 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. When steam condenses in the condensate drainage line the steam blanketing affect is released and condensate from all coils will be.

COM allowed to drain. This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates. Typical problems with group steam trapping: Temperature control problems 2.

Premature component failures a. Freezing in cooler climates 5. Carbonic acid deterioration in the condensate drainage system.

Install one stream trap for each steam heat transfer 2. One of the most important rules for steam trap 3.

Install a visual indication of steam trap perfor- 6. Locate the steam trap below the lowest 8. Check valves should be installed after the steam.
