Traditional Steam Blows

VGI offers both exhaustive steam blows and continuous low pressure steam blows.

Exhaustive steam blows have been utilized in the industry for over 75 years, and was once the standard approach to cleaning steam circuits. This method is similar to the exhaustive air blow technique, except the boiler is fired to generate the pressurized steam used to clean the steam path to the turbines. VGI provides specialized high temperature quick-opening valves for the technique, as well as detailed procedures and design of temporary piping, steam quenching devises, silencers and debris containment equipment. The highly trained Field Supervisors direct plant personnel in the conduct of this method, providing and operating target insertion devices used to assess the final cleanliness of the steam circuit systems.

Low Pressure Steam Blow

Over 20 years ago, VGI staff introduced the continuous low-pressure steam blow technique, which became standard practice for the pre-commissioning cleaning of steam system circuits. This method has now been superseded by our VolSteamBlow^™ process but is still being performed when it is practical and cost effective to the project.

VGI have extensive knowledge with these processes and applies this experience when considering the appropriate solution to be considered for a project.
