Spray Nozzle 11
Spray Nozzle 11 : Two-Fluid Nozzles: (2. 1) Control of Two-Fluid Nozzles: Many applications use two-fluid nozzles to achieve a controlled small drop size over a range of operation. Each nozzle has a performance curve, and the liquid and gas flow rates determine the drop size. Excessive drop size can lead to catastrophic equipment failure or may have an adverse effect on the process or product. For example, the gas conditioning tower in a cement plant often utilizes evaporative cooling caused by water atomized by two-fluid nozzles into the dust laden gas. If drops do not completely evaporate and strike a vessel wall dust will accumulate, resulting in the potential for flow restriction in the outlet duct, disrupting the plant operation
