Abstract The spray drum cooler is one of the key equipment in the rotary hearth furnace process. In order to improve the cooling performance of the cooler,a CFD numerical simulation technology was used to establish a coupling model of the heat transfer process based on the heat transfer characteristics of the external spray cooling system of the drum. The effects of layout parameters such as the number of nozzles,pitch and offset on heat transfer were studied. Effects of nozzle distribution parameters including nozzle number,nozzle distance and nozzle offset on the spray cooling were studied. Too many nozzles with too small distance or too few nozzles with too large distance are not conducive to the cooling performance. An appropriate number and distance have an important impact on the cooling performance of the equipment. Compared to rectangular array nozzles,the parallelogram array has better cooling performance. Finally,the correctness of the research results was verified by specific engineering applications.

Key words： spray drum cooler coupled heat transfer model nozzle distribution wall cooling performance
