The effects of the pulverized coal concentration on ignition distance and ignition temperature can be obtained from the numerical simulation results.
根据数值计算得到的结果找出不同煤粉浓度对着火温度与着火距离的影响,反映出煤粉在富氧微油点火燃烧器内的着火方式的变化。
In order to study the characteristics of microcombustion,a two-dimensional flame-burning model was established,in which the loss of heat and the quenching distance were considered.
为了研究微尺度下的燃烧特性,在考虑散热和熄火距离影响的基础上建立了二维火焰燃烧模型,模型表明在微尺度燃烧中容易发生熄火和吹熄,不容易发生回火。
