Purpose of Carrying out Blowdown in a Boiler

Blowdown is necessary to control the level of concentration of the solids, and this is achieved by the process of 'blowing down,' where a certain volume of water is blown off and is automatically replaced by feed water thus maintaining the optimum level of total dissolved solids (TDS) in the boiler water.

Blowdown Separator - Cleaver-Brooks

2019-9-27 · Steam is rapidly separated from blowdown water and vented out the top of the blowdown separator in a cyclonic spinning action. Cleaver-Brooks blowdown separators are compact and can be quickly installed with few connections. Features: Dissolved solids-protects boiler surfaces from severe scaling or corrosion problems

Boiler Blowdown | Yokogawa Electric Corporation

Manual blowdown is accomplished at most plants by taking boiler water samples once a shift and adjusting the blowdown accordingly. This grab sample approach means that operators cannot immediately respond to changes in feedwater conditions or variations in steam demand and scaling conditions can occur and go undetected until the next sample check.
