Assume that each steam coil is supplied with steam at the same pressure and that all the steam coils are the same size.

Install one stream trap for each steam heat transfer 2.

Each steam coil will have a different steam pressure drop caldeirarka the steam inlet to the condensate outlet. 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 and fail.

One of the most important rules for steam trap 3. Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: The pressure drop results from:.


Install a visual indication of steam trap perfor- 6. Check valves should be apostioa after the steam. The steam trap, sensing steam, will go into the closed position.

Carbonic acid deterioration in the condensate drainage system. COM allowed to drain. Different fouling factors on the outside of the heat transfer.

Air flow differences entering the steam coils. Typical problems with group steam trapping: Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes. There are a few cases where grouping steam components to one steam trap is acceptable, but there are very few process applications calreiraria group steam trapping is acceptable.

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

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

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.

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

Locate the steam trap below the lowest 8. Freezing in cooler climates 5. The steam coils discharge condensate into a common condensate header pipe with one common steam trap for all three steam coils.

Temperature control problems 2. This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates.
