摘要

介绍一种利用沉降炉试验预测煤粉结渣特性的方法

即在沉降炉中布置结渣棒

根据结渣量得出灰渣相对重量等级 ;用吹灰器对灰渣进行吹扫

得出灰渣粘结强度等级 ;对渣型熔融性判断

可得渣型熔融性等级。综合以上 3种方法分析结果

得到沉降炉综合结渣指数。沉降炉试验方法与实际比较接近

预测结果较为直观准确。

Abstract

A method for predicting slagging behavior of pulverized coal by using sedimendation furnace test has been presented. That is to allocate slagging bars into the sedimendation furnace

to obtain relative weight degree of the slag based on the amount of slag; to obtain cohesive strength degree by using sootblower to purge the slag; and to obtain fusion property degree of the slag by judging the fusion property of the slag type. Summing up the analysis results from abovementioned three aspects

the comprehensive slagging index of said sedimendation furnace has been achieved. The said test method is comparatively nearing reality. the results of prediction being comparatively objective and accurate.
