Boiler Pipelines Steam Blowing Procedure: Why and How

Any impurity being dislodged from the boiler or steam pipes during operation of the power plant can lead to a major damage in the turbine, and so the steam boiler and their associated pipes need to be cleaned before rolling the turbine for the fist time. After that the procedure is done regularly to keep the system clean. Steam blowing procedures are used to clean the boiler system and pipe lines.

Boiler Blowdown Control | Water Treatment Services

In industrial steam boilers, blowdown is made up of feedwater which has been treated and heated, but is then flushed to drain rather than going through the conventional heating process where it is converted into steam. Boilers use blowdown to control the levels of suspended or dissolved solids in the water which the boiler uses.
