By establishing a numerical simulation model of the high-temperature flue gas spray evaporation process, the heat transfer and flow processes in the quench tower using 4 different numbers of atomizing nozzles were simulated. Research and analysis were conducted under specific conditions. Different number of atomizing nozzles, the flow field above the quench tower is different, the greater the number of atomizing nozzles, the smaller the area occupied by the air flow, the smaller the conical volume formed by the droplets, the less time it takes to fully evaporate. A single atomizing nozzle cools down faster within 2m from the top of the tower, have the longest trajectory length of the droplet movement, but the time for the droplet to completely evaporate is the longest.
