<p>PURPOSE: To annularly rotate fine fog drips by inclining a discharge orifice at a specified angle with respect to a spray nozzle useful to spray lime slurry in a gas desulfurizing system, and by prevent the deposition and accumulation of the slurry on the tip face of the nozzle. CONSTITUTION: A spray nozzle device 10 for spraying lime slurry into a flue 11 such as an exhaust duct in a boiler of a power plant or the like, with lime as fuel is provided with an air inlet 15 at the upstream end of a cylindrical shell 14, an inlet 16 for a fluid such as the lime slurry is furnished intermediate to both ends of the shell 14 and a tubular nozzle tip member 18 at the downstream end of the shell 14, and a plurality of circumferentially spaced discharge orifices 55 pierce the tip member 18. However, in this case, the axis of each orifice 55 is inclined at an angle of about 10 deg. to a first plane including a central line and also at the angle of 35 deg. to a second plane vertical to the first plane.</p> |
