Glass transition materials for circulating fluidized beds and methods of making and using same
The invention relates to a glass transition material for a circulating fluidized bed as well as preparation and use methods thereof, and belongs to the technical field of comprehensive utilization of fly ash of the circulating fluidized bed. The glass transition material is prepared from 85 to 100 parts by weight of manganese monoxide, 5 to 30 parts by weight of niobium nitride, 5 to 15 parts by weight of polyoxyethylene dodecyl ether and 15 to 40 parts by weight of water. The preparation method comprises the following steps: firstly, mixing the polyoxyethylene dodecyl ether and the water, then adding the manganese monoxide and the niobium nitride, and intensively and uniformly stirring in a stirrer. Manganese monoxide and niobium nitride are uniformly dispersed in a coal sample by using polyoxyethylene dodecyl ether, the liquid phase formation temperature and the liquid phase viscosity are reduced through the mineralization effect of manganese monoxide and niobium nitride, the liquid phase proportion is increased, and the glass transition of circulating fluidized bed fly ash is promoted. Meanwhile, air holes are generated by nitrogen generated at high temperature of niobium nitride, so that the content of hollow microspheres in the circulating fluidized bed fly ash is increased.
本发明为一种用于循环流化床的玻璃化转变材料及其制备和使用方法，属于循环流化床粉煤灰综合利用技术领域。所述的玻璃化转变材料由85~100重量份的一氧化锰、5~30重量份的氮化铌、5~15重量份的聚氧乙烯十二烷基醚和15~40重量份的水制备而成。制备时，先将聚氧乙烯十二烷基醚和水混合，然后加入一氧化锰和氮化铌，在搅拌机中强力搅拌均匀即可。本发明是利用聚氧乙烯十二烷基醚将一氧化锰和氮化铌均匀分散在煤样中，通过一氧化锰和氮化铌的矿化效果降低液相形成温度和液相粘度，提高液相占比，促进循环流化床粉煤灰的玻璃化转变。同时利用氮化铌高温产生的氮气产生气孔，提高循环流化床粉煤灰中空心微珠的含量。
