摘要:

双膛窑石灰煅烧用燃料为煤粉时,煤粉的合理分配对窑内石灰品质和温度分布至关重要。麦尔兹窑和西姆窑的煤粉分配原理大相径庭。本文通过对两种双膛窑煤粉分配的理论计算,提出煤粉分配设计时两种原理各自应注意的事项。

Abstract:

When using pulverized coal as fuel in lime calcination,the pulverized coal distribution is crucial to lime quality and temperature distribution of the double-shaft kiln.And for Maerz kiln and CIM kiln,the pulverized coal distribution principles are quite different.Some points for attention are put forword in this paper for each pulverized coal distribution design by the theoretical calculations on two kinds of double-shaft kilns.
