摘　　要：为研究新型船用焚烧炉处理污油和垃圾的可靠性,通过离散相模型模拟污油单独燃烧,在获得污油燃烧状态后,添加固定床燃烧模型模拟炉膛内污油与固体垃圾同时燃烧过程。结果表明:污油单独燃烧时,炉膛内气流流动顺畅,高温区处于炉膛中心区域,出口烟气温度约1425K,出口氧气浓度为9%。污油与垃圾同时燃烧时,固体垃圾燃尽所需时间约1200s,污油助燃效果稳定可靠。模拟结果为焚烧炉的设计和运行优化提供了理论支持。To study the reliability of waste oil and solid performance in a new marine incinerator,the discrete phase model was used to simulate the separate combustion of oil and waste.After the combustion state of oil obtained,a fixed bed combustion model is added to simulate the simultaneous combustion of oil and solid waste.The results show that when the oil is burned alone,the air flow in the furnace is relatively fluent,and the high temperature area is in the central of the incinerator.The gas temperature at the outlet of the furnace is about 1425K,and the oxygen concentration at the outlet is 9%.When oil and solid waste are burned simultaneously,1200 seconds are needed for solid waste to burn out.
