Boiler Blowdown types and Boiler Blowdown calculation The intermittent blowdown is given by manually operating a valve fitted to discharge pipe at the lowest point of boiler shell to reduce parameters (IDS or conductivity, pH, Silica and Phosphates concentration) within prescribed limits so that steam quality is not likely to be affected.

Water Handbook - Preboiler & Industrial Boiler Corrosion …

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Boiler Treatment Options from Alken-Murray Corporation

You can combine chemical treatment with the removal of solids known as blowdown. Softening agent chemicals, which react with calcium and magnesium to produce a non-adherent, very mobile and readily dispersed sludge, are added to the water to maintain the water at "0" hardness. The non-adherent sludge is removed by either manually wasting boiler

Control valve settings must be adjusted regularly to increase or decrease the blowdown according to control test results and to maintain close control of boiler water concentrations at all times. When continuous blowdown is used, manual blowdown is usually limited to approximately one short blow per shift to remove suspended solids which may have settled out near the manual blowdown connection.

the blowdown method and requirements of steam boiler

Boiler blowdown - WikipediaBoiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within of boiler feedwater for the continuous production of steam required by most boiler applications.
