General Guidelines for the Design of Steam Filtration Installations

The type of the steam filter and the retention rate to be selected depends on the quality of the steam which is required for the specific application. To prevent rapid clogging of the steam filter, it is important to consider the particle load in the pipes. This may require the use of pre and fine filters.

In addition, the flow rate of the steam in an installation should not exceed 25 m/s. In special circumstances, velocities up to 40 m/s are allowable, but the resulting turbulent currents and higher differential pressures must be taken into account.

The differential pressure in a new steam filter installation should be within a range of 0.1 bar to 0.3 bar. Higher temperatures (> 150 °C) require special higher temperature O-rings.
