ABSTRACT:
A Venturi Cooler for flue gas desulphurization devices sprays water through water spray nozzles on pipes positioned perpendicularly to the longitudinal flow direction of the cooler. It is important for the effectiveness of the diffused water that the speed of the flue gas does not fall below a certain limit. A simple adjustment of the cross section of the Venturi cooler to the respective flue gas amount can be achieved by arranging movable baffles on the pipes. The baffles are positionable to reduce the cross section of the Venturi cooler and leave the openings of the water spray nozzles free. They advantageously comprise rotatable sleeves surrounding the pipes and have rotatable flaps for fast adjustment of the cross section.
