APPARATUS FOR SPRAY COMBUSTOR OF BLACK LIQUOR AND BLACK LIQUOR COMBUSTION BOILER USING THE SAME

摘要

PURPOSE:To jet a black liquor as homogeneous dispersed droplets into a furnace and enable stable combustion by providing a special collision plate at the tip of a nozzle for jetting the black liquor into the interior of the furnace. CONSTITUTION:The tip of a jetting nozzle 14 for a black liquor is provided with a collision plate 16. The collision plate 16 is formed into a circular or elliptical shape of nearly left and right symmetry in the extending direction of the central shaft 13 of a jetting hole 15 in the nozzle 14 and the left and right both side ends in the jetting direction of the black liquor are provided with curved parts 17 or weirs for preventing the jetted black liquor from running and a means for nearly homogeneously dispersing and discharging the jetted stream of the black liquor on the collision plate to form free liquor film streams, dividing the resultant streams into droplets of nearly the same size and uniformly dispersing the droplets on the periphery is simultaneously provided.
