By employing a self-designed and self-built atomization test system

the volume flow

spray angle and Sorter particle size(SMD) of large-scale slurry atomization nozzles for flue gas desulfurization were detected

and the relationship between the volume flow rate

atomization angle

SMD and pressure was obtained. The results show that

there is a certain deviation between the measured nozzle's rated atomization characteristic parameters and the measured results at the rated pressure. It is necessary to carry out design optimization for the atomization nozzles used in flue gas desulfurization system. Especially

a certain margin should be considered in the actual engineering design.
