ABSTRACT:
An improved prilling tower is provided for the prilling of molten substances wherein a receiver equipped with an exhaust conduit is positioned below the nozzle during pre-heating of the nozzle prior to normal operation, after the end of a normal operating cycle or when the nozzle is replaced during operation of the prilling tower. Means are provided for moving either the receiver or the nozzle in a horizontal direction so that the nozzle is out of proximity with the receiver during normal operation of the prilling tower. More than one nozzle or more than one receiver can be employed in a prilling tower to provide for continuous operation of the prilling tower during replacement or cleaning of the nozzles.
