【摘要】：为了实现城市生活垃圾的无害化处置,提出了两段热解旋流燃烧装置。该装置的关键技术在于燃烧室内增加了一螺旋体。通过对燃烧室的数值模拟,确定了螺旋体的结构参数,并考察了螺旋体对气相燃烧温度场、烟气平均停留时间和组分浓度分布的影响。结果表明:增加螺旋体后,燃烧室内气体混合均匀,燃烧完全,燃烧情况优于无螺旋体时,满足抑制二VA英的要求。
[Abstract]:In order to realize the harmless disposal of municipal solid waste (MSW), a two-stage pyrolytic swirl combustion device was proposed. The key technology of the device is the addition of a helix in the combustion chamber. Through the numerical simulation of the combustion chamber, the structural parameters of the helix were determined, and the effects of the helix on the gas combustion temperature field, the average residence time of flue gas and the distribution of the component concentration were investigated. The results show that the mixture of gas in the combustion chamber is uniform, combustion is complete, and the combustion condition is better than that without the spirulina, which can meet the requirement of inhibiting 2 VA in the combustion chamber.
