  • Silica Test Kit - rakiro.net

    Silica Test Kit. Silica (sio2) is an oxide of silicon, and is present in almost all minerals. It is found in surface and well water. Silica is a problem for high pressure boilers, as it exhibits enough volatility that high pressure boilers will have silica carry over to the vapour partition.

    2019-7-8 · Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it

  • Scaling in boilers - Lenntech

    If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination. For further information check our web page about silica scaling in boilers.

    A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
