一、改进隧道窑的结构1.降低预热带上下温差隧道窑是一条狭长的通道,窑车在隧道窑运行中的蓄热,以及窑炉的不严密处吸入冷空气使热气体分层,大部分热气体顺着窑内通道上部流向预热带,造成预热带上下温差悬殊,高的竟达300—400℃,这样就不能使制品均匀 First, to improve the structure of the tunnel kiln 1. Reduce the temperature difference between the upper and lower preheat tunnel kiln is a narrow channel, kiln car in the operation of the tunnel kiln heat storage, as well as the furnace inhomogeneous inhalation of cold air to hot gas delamination, Most of the hot gas flow along the upper part of the kiln channel preheat zone, resulting in preheating zone temperature difference between the upper and lower disproportionate, as high as 300-400 ℃, so you can not make the product uniform
