Silica 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 vapor partition. When the steam pressure is reduced in turbines silica will precipitate on the blades as a glassy deposit which reduces efficiency. Measuring silica in water is useful to monitor demineralized for boiler water treatment. Our AQUASOL AE302 – SILICA TEST KIT kits are based on color comparison and are very simple and convenient to use.
