Before starting the petroleum coke calcining rotary kiln, a safety inspection should be carried out and all the safety measures should be taken. This includes checking of the kiln hood or covers to ensure that there are no cracks or holes. The support system for the kiln should be inspected to make sure that it is in good condition. The safety seals on the doors should also be checked.
1. The first step to starting the kiln is to load the coke into the kiln.
The coke should be charged in layers and evenly distributed in the kiln. It is also important to note the quantity of fuel being used to fire the kiln. A proper balance between the fuel and coke should be maintained to ensure optimal performance.
The fuel should then be lit using a flame gun. The flame should be aimed at the fuel and the kiln must be monitored until the flame is established. The flame must then be gradually increased by gradually opening the fuel and waste gas fingers. The flame should also be kept burning so that the coke does not char more than expected.
2.The next step is to increase the air intake by gradually opening the air inlet finger while monitoring the flame.
The aim is to increase the air intake slowly to avoid sudden jumps in the flame. The air intake should be increased until the desired temperature is reached. During this process, the lumpiness of the coke should be monitored to check that it is not powdered or charred.
Once the desired temperature is reached the kiln must be monitored closely to avoid over-firing or burning of the coke. The rotation speed and fire should also be monitored once in 4 hours to ensure that everything is running smoothly.
Parameters for a Successful Operation
There are several parameters that must be considered for a successful operation in the coke calcining rotary kiln.
1.Size of the kiln
The size of the kiln must be selected based on the required output. It is important to calculate the required output and the size of the kiln that is needed to produce the desired output.
2.Fuel and air ratio
The fuel and air ratio must be optimized to ensure efficient operation. The amount of air intake must be adjusted to ensure the desired flame is maintained.
3.Rotation speed
The rotation speed of the kiln must be set according to the required output. Higher rotation speed produces higher outputs but it should not exceed a certain limit to avoid over-firing of the coke.
4.Temperature
The temperature must be maintained according to the requirements. It should not exceed the pre-set temperature as it can lead to over-burning and charring of the coke. It should also not dip below the set temperature as this will result in lower output and efficiency.
Conclusion
The process of starting a petroleum coke calcining rotary kiln and achieving successful operation requires careful consideration and optimization of some key parameters. The fuel and air ratio must be monitored and the kiln rotation speed and temperature must be set and maintained to ensure efficient operation. Strict adherence to safety regulations when starting the kiln is also an important factor to consider.
