      Water-tube boiler - Wikipedia

      A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

      Water Handbook - Boiler Blowdown Control | SUEZ

      Because chlorides do not precipitate in the boiler water, the relative chloride concentrations in feedwater and boiler water provide an accurate basis for calculating the rate of blowdown. The chloride test is unsuitable for this calculation when the feedwater chloride is too low for accurate determination.

      Chloride level in Boiler feed water - Corrosion

      The amount of chloride in the boiler water is a function of the type of boiler and the boiler pressure. High pressure utility boilers have essentially zero chlorides. For low pressure industrial boilers say 150 psi units, boiler water chlorides limits are set on the ideas that:

      boiler water chloride level should be monitored to ensure the blow down rate is correct. If the chloride level is higher than the recommended maximum, more blow down is needed. If it is low, excess blow down is occurring, resulting in wasted chemicals, water, and heat energy. In some cases the chloride level never approaches the recommended
