Abstract
A spray nozzle is used in a process of quenching a hot glass sheet during a laser scoring process or other high energy glass heating process. The nozzle is located in proximity to the glass sheet, creating gas in liquid used to quench the glass located in the nozzle (e.g., water). The gas (e.g., air bubbles) is removed from the quenching liquid. Then, the spray nozzle is used to spray the quenching liquid onto the sheet at a location trailing laser scoring of the sheet. The spray nozzle has a purge opening and tubing leading to a discharge location. The spray nozzle can have a sloped passageway that pre-stages gas bubbles near the purge opening. The spray nozzle can include a cooling coil passing around the nozzle passageway to cool the quenching liquid passing through the nozzle, and increase the solubility of bubbles in the quenching liquid.
