在对首钢矿业公司链篦机-回转窑系统中链篦机进行热工测试的基础上,结合生产设备、工艺及运行特点,分析和诊断了其热能利用状况。结果表明:链篦机炉体散热较小,但存在烟罩内串风严重、预热二段吸风量较大等缺点。针对这些缺点,提出了一些节能措施,为该工艺和设备的进一步完善提供了可靠的理论依据。 Based on the thermal test of the grate in the grate-rotary kiln system of Shougang Mining Company, the heat utilization status of the grate was analyzed and diagnosed based on the characteristics of production equipment, process and operation. The results show that the grate furnace body heat dissipation is small, but there are some shortcomings such as serious string wind in the hood and large amount of suction air in the second stage of preheating. In view of these shortcomings, some energy-saving measures are put forward, which provide a reliable theoretical basis for the further improvement of the process and equipment.
