Rotary kiln large and medium-sized factories often use rotary kiln burner, rotary kiln burner will make coal combustion better, here small make up and we talk about rotary kiln burner related characteristics:
1.The primary air of rotary kiln burner wraps the pulverized coal, which minimizes the contact area between pulverized coal and hot air and effectively reduces NOx emission.
2.The burner has a flame stabilizer in the middle, which can run stably even at low load.
3.Good flame characteristics, so that the production quality of clinker has been greatly improved, and can form a stable kiln skin, effective protection brick.
4.The fravillard burner always follows the first line design, which makes the equipment adapt to the actual operating conditions more accurately and reduces the operating cost.
5.The pressure required for primary air is low, and it can run stably when the pressure is greater than 10KPa. No need to add high-pressure fan, which reduces the transformation cost.
6.In use, it only needs to change the axial position of the cyclone to adjust the degree of cyclone, which is avoided by changing the inlet pressure of the burner to control the momentum An operational error.
7.Make full use of the existing equipment in the process of user transformation and use, no need to transform other ancillary equipment or transform the coal delivery system, save investment, Cost, recovery cycle is short.
8.Axial flow wind is combined into a primary flow channel to reduce the pressure loss between the primary fan outlet and the burner head Loss, more efficient momentum, stronger flame, easier adjustment.
9.The amount of primary wind is about 6-8%, depending on the type of fuel (calorific value of pulverized coal, volatile content, moisture content, fineness, etc.)
The outlet of the channel is designed with small hole diameter variation, which increases the primary wind speed (250m/s to 330m/s) without changing the amount of primary wind.
10. Easier flame adjustment: the cyclone is designed with a gradient Angle of 17 to 50 degrees, and the rotary kiln burner changes the Angle of the cyclone outlet (adjusts the tension)
Change the shape of the flame.Adjust the flame by increasing or decreasing the primary wind pressure.
