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.

The Value of Good Boiler Blowdown Control

In a steam boiler system, blowdown involves removing a portion of the concentrated boiler water and replacing it with feedwater, which is a mixture of condensate and makeup water. Good blowdown control is a critical component of the boiler water treatment program. Boiler blowdown is heated, treated feedwater that is sent to the drain instead of converted into steam. Blowdown is used to control

Blowdown Tanks – Precision Boilers

A blowdown separator is the best choice when space limitations preclude using a large tank to collect and hold the effluent while it cools to an acceptable drain temperature. The blowdown separator accepts boiler blowdown, vents the portion that flashes to steam, but does not store the effluent until it cools.

Heat Recovery from Boiler Blowdown TDS Control

Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.
