Abstract: The invention relates to a device for burning waste liquor and to the disperser in the form of a nozzle used therein. The liquor is dispersed downwards from the corners of a furnace in showers of droplets in the form of full cones. The distance of the dispersers nozzle outlets from the bottom of the furnace is 45-60 percent of the sum of a narrower and a broader side of the furnace''s bottom plane and the geometrical axis of each of the dispersers is in a plane which forms an angle of 40* -50* with the sidewalls of the furnace, and the axis of each disperser forms an angle of 35* -55* with the vertical line of intersection of the furnace sidewalls. The top angle of the outlet in the outlet member is 60* -90* and the diameter of the outlet is 30-45 percent of the inner diameter of the nozzle body. The body of the nozzle comprises a detachable vortex element having four spiral grooves at an angle of 45* -60* to the transverse axis of the nozzle. The crosssectional flow area of the grooves is 45-55 percent of the inner cross-sectional area of the nozzle body portion.
