The spraying of a fluid to cool gas, solids or even other fluids is a common industrial application. Cooling is achieved by spraying a cooler liquid that absorbs and carries away heat. Heat energy is transferred to the coolant either by warming it in its still liquid state or by evaporating/boiling the liquid into a gaseous state (phase change).
Spray nozzles are used cool a variety of processes in the Mining industry.
- Cooling of gasses can be achieved by spraying a fine mist of coolant into the gas stream
- The cooling of fluid beds
- The cooling of reaction tanks
