小型农村固体废弃物焚烧炉炉拱结构的研究

Research on the arch structure of small rural solid waste incinerator

对处理农村固体废弃物的小型L型火焰焚烧炉炉拱的结构参数进行研究。提出一种用于L型火焰焚烧炉的新型炉拱结构。采用正交试验设计方法,确定了8种不同的试验条件。炉拱的最佳无量纲准则为:H/L=0.333,H/L=0.12,前拱角度为45°。通过热态试验验证以农村固体废弃物为燃料的L型火焰焚烧炉的炉拱结构的有效性。

In this article,investigations on the structural parameters and aerodynamic characteristics of the furnace arches of a small scale L-shaped flame incinerator for the disposal of rural solid waste are carried out.Eight different test conditions are determined by using orthogonal experimental design method.The optimum dimensionless structural parameters of the furnace arch are:H/L=0.333 and H/L=0.12 with the front arch angle of 45°.The effectiveness of configuration of arches as well as combustion air supply ratio for the L-shaped flame grate incinerator fueled by rural solid waste is verified by hot test.
