ANSYS Fluent Modelling of an Underexpanded Supersonic Sootblower Jet Impinging into Recovery Boiler …

Sootblowers generate high pressure supersonic steam jets to control fireside deposition on heat transfer tubes of a kraft recovery boiler. Sootblowing is energy expensive, using 3-12% of the mill's total steam production. This motivates research on the dynamics of sootblower jet interaction with tubes and deposits, to optimize their use. A CFD investigation was performed using ANSYS Fluent 15

Part Retractable Sootblower | Clyde Bergemann

Clyde Bergemann's Part Retractable Sootblowers are the solution for the efficient cleaning of heating and reaction surfaces of superheaters, economisers, airheaters and gasheaters with heavy fouling and flue gas temperatures < 800 °C. This type of sootblower is a cost-effective solution especially for medium sized boilers.

Kraft Recovery Boilers - Sootblowers (Russian)

When black liquor is burned, a significant quantity of ash is produced. Some of the ash accumulates on the boiler tube surfaces, reducing the boiler heat transfer efficiency. Eventually, the boiler flue gas passages can become plugged, and as a consequence, the boiler has to be shut down and washed with water to clean out the passages. This unscheduled shutdown interrupts production and incurs

Recovery boiler - Wikipedia

Abstract (summary): The fouling of heat transfer surfaces in kraft recovery boilers is a significant concern for the pulp and paper industry. The usual approach to controlling fouling is the use of so-called ``sootblowers,'' that utilize boiler steam to generate supersonic steam jets that are literally used to knock deposits off of the boiler tubes.
