煅烧回转窑窑口掉砖探讨

Discussion on the problem of kilneye brick dropping of calcination rotary kiln

在热风炉的日常维护和检修上，旋流顶燃式热风炉避免了燃烧室内部掉砖阻碍煤气畅通以及煤气泄漏等现象，减少了检修量，有利于安全生产。

There are also several advantages for the hot-blast stove having spiral flow and top combustion , such as less maintenance , safety production etc.

从煅烧回转窑运行过程中热胀冷缩引起砖缝的变化，以及钢筒体对砖产生的应力等方面，分析窑口掉砖的原因。

The causes of the problem of kilneye brick dropping has been discussed based on the changes of brick gaps caused by the expanding with heat and contraction with cold during the operation of the calcination rotary kiln .

它要花掉一些砖。

It took some real hacking .
