Boiler Blowdown | Yokogawa China Co., Lt

Boiler problems are avoided by periodically discharging or "blowing down" water from the boiler to reduce the concentrations of suspended and total dissolved solids. Surface water blowdown is often done continuously to reduce the level of dissolved solids, and bottom blowdown is performed periodically to remove sludge (suspended solids) from the bottom of the boiler.

2020-3-12 · The nature of the scale formed depends on the chemical composition of the concentrated water. Normal deposit constituents are calcium, magnesium, silica, aluminum, iron, and (in some cases) sodium. The exact combinations in which they exist vary from boiler to boiler, and from location to location within a boiler (Table 12-1).
