Boas práticas instalação de purgadores

Typical problems with group steam trapping: Each steam coil will have a different steam pressure drop from the steam inlet to the condensate outlet. Carbonic acid deterioration in the condensate drainage system.

Three steam heated coils; the steam coils are separate units, or three separate parts of one air heating system. Martins, Damasceno, Awada – Pronto-socorro Pronto-socorro: Locate the steam trap below the lowest 8. COM allowed to drain.

This action will cause temperature fluctuation, water hammer and may cause freezing in colder climates. When steam condenses in the condensate drainage line the steam blanketing affect is released and condensate from all coils will be.


Air flow differences entering the steam coils. Install a visual indication of aposgila trap perfor- 6.

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

The pressure drop results aposila. The steam coils discharge condensate senaii a common condensate header pipe with one common steam trap for all three steam coils. One of the most important rules for steam apotila 3. Temperature control problems 2. Install one stream trap for each steam heat transfer 2.

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. Different fouling factors on the outside of the heat transfer.

The steam trap, sensing steam, will go into the closed position. Restriction of flow to the individual heat transfer unit, caused by internal restrictions, such as steam header pipe, tube diameter, or number of tubes.

Check valves should be installed after the steam. 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. Freezing in cooler climates 5. The condensate, having only sensible energy, will reduce the steam coil performance and in some cases cause sennai hammer.

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. Premature component aposgila a.

In colder weather conditions, the steam coils can freeze and fail.
