摘要

选择准东高铁煤将军庙煤作为研究对象

通过改变添加剂Fe

含量

研究铁含量对准东高铁煤灰熔融特性的影响

进一步分析准东高铁煤煤灰中矿物的演变规律

并计算分析煤灰的黏度。结果表明:在将军庙原煤煤灰中

低熔点矿物钙镁黄长石的生成是其灰熔融温度较低的主要原因;当将军庙煤中Fe

质量分数为8%时

煤灰的变形温度(DT)、软化温度(ST)均降至最低

主要原因是生成了大量铁橄榄石;将军庙煤中Fe

质量分数大于8%时

煤灰矿物中出现高熔点矿物的莫来石

使其DT和ST均上升;温度超过1 000 ℃后

随着温度的继续升高

煤灰的黏度逐渐减小;Fe

质量分数为8% 的煤灰黏度最先进入煤灰的强沉积区间

沾污结渣情况最严重;温度为1 300 ℃时

不同Fe

质量分数下煤灰的黏度基本相同。

Abstract

The Jiangjunmiao coal of Zhundong high-iron coal was selected as the research object

and the effect of iron content on the ash-melting characteristics of Zhundong high-iron coal ash was investigated by changing the content of Fe

. Moreover

the evolution of minerals in the coal ash of Zhundong high-iron coal was analyzed

and the coal ash viscosity was calculated and analyzed. Results show that the formation of low melting point mineral calcium-magnesium yellow feldspar is the

main reason for its lower ash melting temperature. When the Fe

content in the Jiangjunmiao coal is 8%

the ash deformation temperature (DT) and softening temperature (ST) decrease to the lowest

which is mainly due to the generation of a large amount of iron olivine. When the Fe

content in Jiangjunmiao coal is higher than 8%

mullite

a high melting point mineral

appears in the ash minerals

causing both DT and ST of coal ash to increase. After the temperature exceeds 1 000 ℃

the viscosity of the coal ash gradually decreases with the increase of temperature. The viscosity of coal ash with 8% Fe

content is the first to enter the strong deposition zone of coal ash with the most serious staining and slagging. At temperature of 1 300 ℃

the viscosity of coal ash with different Fe

contents is basically the same.
