輪窑操作的特点是将煤直接撒在碼于窑內的制品上,而沒有特定的爐灶。为了使煤从窑面的火眼洞投下,能分布均勻充分燃燒,就需在对准加煤孔部位选择最适当的坯垛形式。即为我們通常所称的“火眼”。火眼形式的好坏,决定着燃料——煤——能否充分燃燒,是降低轮窑煤耗的主要关鍵之一。同时对焙烧进度也有巨大影响。火眼处理不当,往往造成煤耗大、产量低、質量差(特别是黑头砖多)的后果。几年来我厂曾采用多种不同的火眼形式,不断摸索改进,从实际效果比 Wheel kiln operation is characterized by the fact that the coal is directly sprinkled on the product in the kiln without a specific stove. In order to make the coal drop from the fire hole of the kiln surface and to distribute it evenly and fully, it is necessary to select the most appropriate blank form at the location of the coal filling hole. That is what we commonly call “fire eyes.” The quality of the form of fireholes determines whether fuel—coal—can be fully burned and is one of the main keys to reducing coal consumption in wheel and kiln. At the same time, it has a great influence on the roasting progress. Improper handling of fire eyes often results in large coal consumption, low production, and poor quality (especially black bricks). Over the past few years our factory has used a variety of different forms of fire, constantly explored improvement, from the actual effect than
