在锻造加热炉的烟道内我们安装了自行设计的板式冲击空气换热器,它能将助燃空气预热,从而实现了余热利用,改善了燃油雾化条件,收到了较好的节能效果。换热器在加热炉内的位置见图1。换热器结构如图2所示。整个构件由3毫米的钢板焊接加工而成。外套与烟气接触,被加热。冷空气从内套的密 In forging furnace flue we installed a self-designed plate impact air heat exchanger, which can preheat the combustion air to achieve the use of waste heat to improve the fuel atomization conditions, received a better energy saving. Heat exchanger in the furnace position shown in Figure 1. Heat exchanger structure shown in Figure 2. The entire structure is made of 3 mm steel plate welded. The coat comes in contact with the flue gas and is heated. Cold air from the inner sleeve of the dense
