A device for restraining a copper metallurgy smelting furnace from generating coking and a use method, and belongs to the technical field of copper smelting. The device is characterized in that waste heat boiler outlet smoke is used for heating prepared-in high-concentration oxygen-rich secondary air through a heat exchange device, the secondary air mount is reduced, anthracite is prepared in copper concentrates, the smelting oxygen-rich air concentration is improved, and therefore coking in the smelting furnace and other hot boilers is restrained or controlled. The method is applicable to use of various copper metallurgy smelting furnaces, and the beneficial effects of being small in investment, low in running cost, easy to operate and the like are achieved. 种抑制铜冶金熔炼炉产生结焦的装置及使用方法，属于铜冶炼技术领域。其特征是利用余热锅炉出口烟气通过换热装置对配入高浓度富氧二次风进行加热，减少二次风量，并在铜精矿中配入无烟煤，提高熔炼富氧空气浓度，以此抑制或控制熔炼炉及其余热锅炉内的结焦。此方法适用于各种铜冶炼熔炼炉使用，具有投资小、运行费用低、操作简单等特点。
