Read MoreWater-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high

Read MoreIn water, the specific conductance, or ability to carry an electric current, is directly related to the quantity and mobility of the dissolved solids. As such, specific conductance is widely used to monitor boiler makeup and condensate purity and to control boiler and cooling system blowdown.
Read MoreShell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam at 100°C.
