摘　　要：在船用焚烧炉整体结构初步设计的基础上,将炉膛、气冷壁等作为一个整体进行了三维冷态湍流数值模拟.通过模拟分析,得到了炉体内部不同区域垂直和水平方向的速度矢量图、压力分布等值线图.数值模拟为炉体结构的进一步优化气冷壁到炉膛的气孔大小和布置提供了重要的依据,同时也对燃烧的优化组织及其控制具有重要的指导意义.Based on the preliminary design of the marine garbage incinerator, the furnace and air cooling wall are made as a whole to carry out a three-dimensional numerical simulation in cold station.Through simulation analysis, the velocity vector contour and pressure distribution contour of different regions of the internal furnace in vertical and horizontal direction.Numerical simulation of the structure provides an important basis for further structure optimization of air pore size and layout from air-cooled furnace wall to the furnace.It also has the important guiding significance for combustion optimization and control.
