Development Trend of Coal Dust Burners of Rotary Kiln

Compared with rotary kiln, coal dust burners is smaller and cheaper. But in fact, the performance of the rotary kiln burner plays an important role in the combustion system, which makes the coal dust burners get special attention from the cement industry at home and abroad. The good performance coal dust burners has a significant effect on the growth of the economic benefit of the enterprise.
In industrial furnace, cement rotary kiln is the earliest equipment for coal powder as fuel, however, there has been a lack of in-depth research on the pulverized coal burner of cement rotary kiln, so the coal dust burners used in the rotary kiln has been a very backward single duct pulverized coal burner. Coal is the cheapest fuel for oil and gas, especially after the 70s oil crisis, the European Fund Research International (IFRF) directly subsidy to the cement rotary kiln coal and petroleum coke to carry out research work. With the strong support of IFRF, the coal dust burners of rotary kiln quickly developed from single duct to double channel, three channel, four channel and even five duct. Both theory and practice have proved that the better burner air duct is, the more performance it has, but the more complex the structure is, the heavier the weight, the more expensive the price.
At present, there are some obvious development trends of the coal dust burners in the rotary kiln:
1) Development from the three duct to the four duct.
2) Development from the split type to the swirl type.
3) Development from the burning of high quality coal to burn low quality coal and waste fuel.
4) in the large and medium scale production line, the introduction of the burner from the introduction to the domestic development.
As a production, design and processing machinery and equipment manufacturers, Henan Zhengzhou Mining Machinery Co. Ltd. has accumulated years of design experience in the basis of providing the calcination process of rotary kiln coal dust burners. According to continuous improvement, it provides the design and production of cyclone four channel coal burner LY series, welcome to consult.
