灰熔融性是判别结渣的主要依据之一,但部分准东煤灰熔融温度高,仍具有严重结渣倾向.为了分析准东煤灰熔融性与结渣倾向不吻合的原因,采用煤质数据对比分析法,研究了准东煤灰熔融性与煤灰成分的相关性,说明部分准东煤灰熔融性高主要是煤灰中碱性氧化物含量高引起,得出了准东煤的软化温度与煤灰中的碱性氧化物成分相关性较好,可用碱性氧化物含量/(碱性氧化物含量+酸性氧化物含量)或者当量碱性氧化物含量进行灰熔融性的初步判别,可为准东高钠煤的灰熔融性检测、锅炉设计及电厂的安全燃用提供参考和依据.

Ash fusibility was the main basis for slagging evaluation. Some kinds of Zhundong coal with high ash fusion temperature still slagged seriously. In order to analyze the correlation between Zhundong coal fusibility and ash composition,the coal quality data were ana-lyzed in the paper. The results showed that,high basic oxide in coal ash led to high fusibility of Zhundong coal. The fusion temperature of Zhundong coal had a good correlation with basic oxide components,the ash fusibility could be preliminarily judged by the ratio of basic ox-ides and sum of basic oxide and acid oxide or equivalent basic oxide. This conclusion provided reference for coal ash fusion temperature test,boiler design and power plant safe operation of Zhundong coal.
