Silica Scaling in Boilers - Lenntech

To minimize this problem, the quantity of silica in the steam must be controlled. Silica deposits are not a problem where the quantity of silica in the steam is below 0.02 ppm. The proper boiler water silica level necessary to mantain less than 0.02 ppm silica in the steam is shown in the figure below.

Boiler Steam drum internals and function

Steam drum internals for typical type of boiler are shown. The internals include separation devices to assist in separating small droplets of boiler water from the steam. Boiler water in the steam will cause scaling of the superheater and steam turbines.Baffles, chevron types separators and demister pads are used to minimize boiler water carryover.

Steam - Wikipedia

2019-10-14 · Steam is water in the gas phase, which is formed when water boils or evaporates. Steam is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as this water vapour condenses. At lower pressures, such as in the upper atmosphere or at the top of high mountains, water boils at a lower
