【摘要】:为了提高热风炉蓄热室的换热效率,以硅质格子砖为研究对象,在不改变格子砖设计面积和材质的情况下,研究了材料本身的热导率对热风炉换热效率的影响。结果表明,提高格子砖的热导率可显著提高热风炉的换热效率:当硅砖的热导率由1.8 W·(m·K)~(-1)增加到2.3 W·(m·K)~(-1)时,可使热风炉燃烧期时间缩短8.2%。可见,高导热硅质格子砖的使用,可显著提高热风炉的节能效果。
[Abstract]:In order to improve the heat transfer efficiency of the heat storage chamber of hot blast furnace, the effect of the thermal conductivity of the material on the heat transfer efficiency of the hot blast furnace was studied without changing the design area and material quality of the lattice brick. The results show that the heat transfer efficiency of hot blast furnace can be significantly improved by increasing the thermal conductivity of lattice brick. When the thermal conductivity of silicon brick is increased from 1.8 W (m K) ~ (-1) to 2.3 W (m K) ~ (-1), It can shorten the burning time of hot blast stove by 8.2. It can be seen that the use of high thermal conductivity siliceous lattice brick can significantly improve the energy-saving effect of hot-blast furnace.
