Note
As well as removing sludge from the boiler, a second and equally
important function is to maintain the TDS (totally dissolved solids) level to
within the required limits. The amount of blowdown, and hence time
required, it dependent on the amount of TDS in the raw water supply, the
percentage condensate return, water treatment chemicals added and the
number of the hours a day operation. In order to establish the required
blowdown rate, consult your water treatment specialist who will
recommend a water treatment program in terms of appropriate
chemicals and the required blowdown rate, which takes these factors
into account.
