A spray nozzle for use in the elbow interconnecting a coke oven ascension pipe and a main, characterized in having frusto-conical nozzle orifices to generate sprays which commpletely cover the elbow cross section only when they reach the transition between the elbow and the coke oven main. The invention resides in the realization that in order to optimize the performance of the nozzle, there must be a specified relationship between the inlet diameters of the frusto-conical orifices, the outlet diameters of the orifices and the radial and circumferential distances between the centers of orifices arranged in concentric circles. |
