Fire Tube Boiler Water Limits For Silica


Boiler – Fundamentals and Best PracticesA fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four boiler tube - Search boiler tubevalues are for high "ids: lower values are for low solds in the boiler water Dictated by boiler treatment e These values are exclusive of silica.

SiO 2 0.2 to 0.5 kcal·m –2 ·h –1 per degree C. This scaling is mainly caused by the presence of calcium salts (carbonates or sulphates) in the water. These salts are less soluble when hot than when cold or when there is an excessively high level of silica in relation to the alkalinity of the water in the boiler.
