摘　　要：为研究富氧燃烧技术在陶瓷窑炉中实际传热现象,以液化气为燃料通过燃烧试验台进行富氧燃烧的试验。通过氧浓度和助燃气体温度对温度梯度、最高温度及最高温度点位置的影响研究,分析不同富氧燃烧条件与窑炉内温度分布的变化关系及规律。研究结果表明,在富氧燃烧条件下,随着氧浓度增加,1200℃以上高温区范围扩大,最高温度明显提高,温度分布均匀性更好;在氧浓度较高的条件下,助燃气体温度的升高更加有利于提高实际燃烧温度和传热空间的平均温度。Using liquefied petroleum gas as fuel on burning test beach for oxygen-enriched combustion, to study actual heat transfer phenomenon of oxygen-enriched combustion technology in ceramic kiln. Discussed the effect of oxygen concentration and comburent air temperature on the temperature gradient, maximum temperature and the highest temperature position. And analysis different oxygen-enriched combustion conditions effect of temperature distribution in ceramic kiln. The results showed that oxygen-enriched combustion conditions, as oxygen concentration increases, more than 1200℃ temperature area extends, Maximum temperature increased significantly, uniformity of temperature distribution increased. Under the conditions of higher oxygen concentrations, comburent air temperature rises more helps improving the practical combustion temperature and average temperatures.
