In October 2020，Huijin intelligent equipment HJ energy saving burner was officially put into operation in a large non-ferrous metal smelting enterprise in Yunnan,opening a new journey for Huijin to enter the field of non-ferrous metals.Since its establishment in 2014, Huijin Intelligent equipment HJ energy saving burner has made remarkable achievements in cement, lime, alumina and other fields by virtue of its excellent product quality and energy-saving innovation in science and technology.The cooperation with large-scale non-ferrous metal smelting enterprises in Yunnan is another innovative breakthrough for Huijin Intelligent Equipment.

As is known to all, non-ferrous metal smelting produces atmospheric pollutants such as sulfur dioxide and nitrogen oxide. Under the current situation, the emission standards of atmospheric pollutants in the nonferrous metal industry have been greatly improved, and "net zero emission" and green industry have become the development trend of non-ferrous metal industry and the cornerstone of sustainable development of the industry.In the smelting industry, the burner is the core equipment of the boiler. Due to the influence of environmental factors during operation, it becomes the key to the normal operation of the boiler. Therefore, the combustion stability of the burner must be analyzed in operation.

HJ energy saving burner is a new generation of combustion equipment developed by Henan Huijin Intelligent Equipment Co., LTD.The potential of burners for kiln is fully exploited and a series of technological innovations are made,The spiral design with half circle and inclined taper is adopted in the structure of the flow passage. The shape of the flame is like the pen edge, complete flame shape, high strength, good rigidity, no fluctuation, strong stability, ensuring the normal operation of the boiler.

The HJ energy saving burner shows strong "power" in the process of energy saving and emission reduction.The primary air consumption of HJ energy saving burner is less than 5.7%, The external axial wind and swirling wind are convenient and flexible adjustment,Pulverized coal burns out rate is efficiently,Compared with the traditional burner, the coal saving is up to 1kg-2kg;Combustion system with air distribution technology greatly reduced installed capacity configuration, compared with the traditional burners can save electricity up to 15%-35%.Due to the significant reduction of primary air consumption, good flame shape, strong stability, and reduced peak temperature, the flame dynamic time at high temperature is short, effectively reducing the production of nitrogen oxides.

To prevent and control industrial waste gas pollution and eliminate the backward technology and equipment that seriously pollute the environment, HJ energy saving burner starts from the source and radically reduces the generation and emission of pollutants. Its overall performance is in the advanced technology level of pulverized coal burner at present, and it is the solid backing for enterprises to make progress together in terms of environmental benefits and economic benefits.
