WINGJET

For Flue Gas Desulfurization in Fossil-Fuel-Fired Power Stations

The EKATO WINGJET was developed for the absorber towers in flue gas desulfurization plants and is the most successful and efficient impeller for this application. For other applications where side-entry agitators are required, this impeller becomes more and more popular, too.

The WINGJET, which is used in flue gas desulphurisation units of fossil fuel-fired power stations is a good example of an impeller with specially optimised flow properties. The primary tasks of these impellers, which are mostly side-entry, is to suspend gypsum and to disperse air in very large absorber tanks. In designing the EKATO WINGJET specially for this process, the emphasis was on increasing the efficiency. The blade design was based on the required uniform power transmission over the length and circumference of the blades. The winglets suppress vortexing around the tip of the blade, thus preventing erosive wear in this region that occurs with conventional propellers.

What does “Number of sealing faces” mean?

Single-acting mechanical seals
These seals have one sealing surface and only seal in one direction. They are generally simpler in design and are commonly used in applications where pressure is applied from only one side.

Double-acting mechanical seals
These seals have two sealing surfaces and can seal in both directions. They are ideal for applications where pressure may come from both sides or where a higher sealing performance is required.

Triple-acting mechanical seals
These are less common and used in specialized applications that require a more complex sealing setup. They offer additional sealing surfaces or mechanisms to ensure reliable sealing even in highly demanding environments.
