How to control the temperature of the rotary kiln? Calculation method of the core temperature of the

To control the temperature of the rotary kiln, the first thing to solve is the measurement problem of the temperature of the rotary kiln, with the SLD-RFT series rotary kiln wireless temperature measurement system, the wireless temperature measurement system specially designed for the rotary kiln. Multi-point and single-point can be used in any combination. No wiring for power supply.

SLD-RFT-3 rotary kiln wireless temperature measurement system is one of the SLD-RFT series wireless temperature transmitters, which is a wireless temperature measurement system specially designed for the occasion of three-point simultaneous temperature measurement, which can simultaneously sample the temperature of three thermocouples of the same type, and then wirelessly transmit them to the display instrument and the host computer, not only display the temperature of the three channels at the same time, but also have dual alarm monitoring, 4 20mA transmission and modbus-rtu communication functions. It is convenient to use for the temperature measurement of the kiln head, kiln and kiln tail of a rotary kiln.

The rotary kiln wireless temperature measurement system can be realized.

Temperature measurement in rotary kilns has long been considered a problem, as the rotation of the rotary kiln has caused many inconveniences to the measurement.

Although the actual operation of rotary kiln temperature regulation, although the control methods are different, the ultimate purpose is to coordinate the temperature of each part of the rotary kiln, and the temperature distribution of the whole kiln is uniform and reasonable, and the temperature in the rotary kiln is controlled in the following four types.

1) The temperature is controlled by adjusting the rationing amount of fuel, while the feeding amount and the speed of the rotary kiln remain unchanged;

2) Variable material volume to control the temperature;

3) Control the temperature by adjusting the corresponding changes in the amount of feed and the amount of fuel;

4) The temperature is controlled by adjusting the speed of the rotary kiln. Hongke Heavy Industry provides you with hope.

Dear, hello, I am glad to answer for you, the calculation method of the center temperature of the rotary kiln A: The temperature in the cylinder of the rotary kiln is higher than the firing zone, the maximum temperature of the air flow can reach 2100, and the temperature of the calcined clinker is between 1350 and 1650. The surface temperature of the fire brick layer with good kiln skin protection is between 600 700, when the kiln skin falls off, the inner surface temperature of the refractory brick layer can reach 1300 1400, when the thickness of the good refractory brick layer is 200mm, the thermal conductivity of different types or varieties of refractory bricks is also different.

With the extension of the use time of the kiln lining, the inner surface of the refractory brick will be abrasive and damaged, making it thin, which has a great impact on the surface temperature of the kiln cylinder. In addition, when 40mm thick refractory mud and pads are used to build fire bricks with 3mm thick ceramic fiber felt, it also has a certain impact on the outer surface temperature of the kiln barrel. The difference in the surface temperature of the kiln cylinder at the installation site of the rotary kiln equipment can not only reflect the performance of different varieties of kiln lining, kiln lining damage and masonry method, but also reflect the state of the kiln skin.

Therefore, the infrared scanning detector of the temperature of the rotary kiln cylinder is now set up to detect the surface temperature of the kiln cylinder, which plays an important role in ensuring the high-quality, high-yield, safe and stable long-term operation of the rotary kiln. In order to avoid too many emergency kiln shutdowns, the outer surface temperature of the rotary kiln is set to 400, and the infrared detector of the barrel temperature of the rotary kiln at home and abroad is set and controlled in this way. That is to say, in the operation of the rotary kiln equipment, as long as the surface temperature of the kiln body does not exceed 400, there is no need to stop the kiln urgently, where it should be noted that the infrared thermometer measures the temperature of the outer surface of the kiln cylinder, and the inner surface temperature in contact with the refractory brick is generally about 5 10 higher.

The temperature difference between the inner and outer surfaces of the kiln cylinder is related to the variety of refractory bricks, that is, the larger the thermal conductivity of the fire bricks, the higher the temperature of the inner surface of the cylinder, the greater the temperature difference of the outer surface of the cylinder. In order to ensure production safety, the operating temperature of the kiln surface can be controlled within 370, and once it exceeds 370, it will be adjusted accordingly to prevent unnecessary losses caused by the "red kiln".

How should you look at the decomposition temperature of the rotary kiln, hello! The carbon rotary kiln is called "normal fire", which is the appropriate firing temperature. Generally speaking, "normal fire" has the following characteristics in a rotary kiln:

The flame in the kiln is shining, the shape is complete, stable and powerful, and there is a certain length. The material is slightly white, the material at the fire point rolls flexibly, the clinker is fine and uniform, and there is a certain vertical weight. The "black shadow" is stable at a certain position, and the boundary between the high temperature zone and the "black shadow" is not very obvious.

The color of the kiln skin is basically the same as the color of the material. The so-called "fire" is that the firing temperature is too high. Generally speaking, the flame is white and dazzling during the "big fire", and the material at the fire point is higher with the kiln wall of the rotary kiln, the tumbling is not flexible enough, and the clinker is coarse and sometimes even agglomerates.

If the fire is too large, the materials of the firing belt will be sintered into a group, and they cannot roll over with the wall of the rotary kiln, forming a "flow fire", which will seriously affect the rotary kiln skin and lining. The so-called "desertion fire" means that the firing temperature is too low. In the case of a "small fire", the flame turns red, the "black shadow" moves to the kiln head, and in severe cases, the raw meal in the back rushes to the front like water.

Due to the difference in the color discrimination ability of the fire watcher and the color of the fire goggle, there will be a difference in the judgment of the size of the fire, so the fire goggle with the same depth should be used. At the same time, different fire colors should be controlled according to the different refractory degrees of materials to prevent adverse consequences. Hope it helps!
