The results show that the fields of temperature and flow which take place in the tuyere zone of BF are beneficial to the pulverized coal combustion and the higher oxygen concentration is good for the earlier ignition and higher burn-out rate of pulverized coal .

结果表明，高炉风口产生的 回旋 区流场及温度场有利于煤粉的燃烧，而氧浓度大则有利于煤粉较早着火及较高的燃烬率。
