摘要: 为减小隧道窑预热带上下温差,利用计算机数值模拟对预热带调温烧嘴和预热带温度场进行研究.研究结果表明:在调温烧嘴其它操作参数不变时,预热带物料区上下温差随喷入窑内焰气占来流烟气量比例(1.5%~10%)、焰气速度(60~110 m/s)、焰气与来流烟气温差(0~500 K)的增大而减小.调温烧嘴的布置宜采用相错布置方式.

Abstract: In order to reduce the temperature difference of tunnel kiln preheating zone from top to bottom, Thermostat burner and temperature distribution was researched by computer numerical simulation. The temperature difference of material zone in preheating zone of tunnel kiln is decreasing when the ratio (1.5%~10%), velocity (60~110 m/s) and temperature (0~500 K) of flame gas injected are increasing if the thermostat burner's other operation parameters are fixed. Burner thermostat suitable arrangement is staggered.
