The burning of coal in urban and rural areas in northern China is inevitable, and many of them have not taken any measures to reduce the dust and smoke. The cumulative emissions of sooth have big impact on the quality of the air. Our project is to design and manufacture a kind of dust reduction which is installed inside the flue. Through the comparison of the combustion test, it is proved that the purpose of reducing soot emission is realizable. The device is mainly divided into two parts, one is activated carbon barrel and the other is sliding lid box. The principle of the device design is easy to use which is suitable for installation and cost is not high. It can have a certain effect on the environment.
