Abstract: A nozzle ring assembly comprising a nozzle ring having a plurality of recesses for accepting a plurality of nozzle tips; a plurality of a first type of nozzle tips from which water emanates, the first type of nozzle tips being arranged about the face of the nozzle ring so that water emanating therefrom contacts the fireproofing material at a first distance from the nozzle ring, wherein the first type of nozzle tips provides a water spray for at least essentially uniformly mixing water and the fireproofing material; and a plurality of a second type of nozzle tips from which water is emanates, the second type of nozzle tips being arranged about the face of the nozzle ring so that water emanating therefrom contacts the fireproofing material at a second distance greater than the first distance, wherein the second type of nozzle tips provides a water spray that provides additional impact pressure of the fireproofing material against the surface.
