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.
