目前,广泛应用的工业窑炉一般都是以耐火砖和轻质砖作炉壁的。在炉子加热时,热量传给耐火砖,一部分储蓄于炉墙和炉底(蓄热损失),一部分经炉壁、炉顶散于大气中(散热损失),如何减少热量损失是提高窑炉的热效率和节约能源的重要环节。一、常用窑炉炉壁的热工特性为减少炉体热损失,常用各种绝热材料作炉子砖砌体的绝热层,图1是 At present, widely used industrial kilns are generally made of refractory bricks and lightweight bricks for the furnace wall. When the stove is heated, the heat is transferred to the refractory bricks. Some of the heat is stored in the furnace walls and the bottom of the furnace (loss of heat storage), part of the furnace walls and the top of the furnace are scattered in the atmosphere (heat loss), and how to reduce the heat loss is to raise the kiln Thermal efficiency and energy conservation an important part. First, the thermal properties of the furnace wall commonly used In order to reduce the furnace heat loss, a variety of commonly used insulation materials for thermal insulation brick masonry, Figure 1 is
