The Specific Selection Methods for Rotary Kiln Burner

Rotary kiln has such advantages as long staying time and excellent thermal insulation, and the rotary effect can make the materials inside it fully stir, which makes rotary burner become the ideal burning system of all waste materials. The rotary burner has outstanding working effect on waste materials containing glass or high silicon as these waste materials will seriously damage the system of other types. Burner belongs to the heat source device, which is an important part in the rotary kiln system, and is also the main energy consumption equipment. Here we analyze what are the specific requirements for choosing the rotary kiln burner: 1. The rotary kiln burner of large and medium-sized factory should adopt multi-channel burner with injection ignition device, and set up a set of oil supply system for the burner ignition. The length and the Angle of the burner can be adjusted, and it is appropriate to use hanging or fixed support type. 2. Rotary kiln burner should be determined according to the type kiln and coal quality. Multi-channel burner is a pulverized coal burner that is advanced in the world and is widely applied in the rotary kiln equipment. Its characteristic is: an air volume is small, can adjust the shape and length of flame, flexible for different ash content of coal quality, strong adaptability to different pulverized coal fineness, especially in the case of higher ash content, make it achieve complete combustion, thus not only better adapt to complex combustion condition, increase the combustion efficiency, but also has more obvious effect on reducing energy consumption of rotary kiln equipment. 3. The volume of air required by multi-channel coal burner should be no greater than 15%. The proportion of wind and cold wind can be determined according to the different types of coal burner. 4. A wind fan of rotary kiln should be equipped with system accident or standby blower fan, to ensure production safety and stable operation of equipment. china magnetic separator: http://www.china-mills.com/p17.html
