The article describes the development of a mathematical model of thermal state of the unit lining for calcining petroleum coke.Determination of the temperature fields of the lining will allow you to control the quality and volume of the resulting technological product, assess heat losses from the surface of the unit to the environment, and observe thermal conditions during start-up operations and shutdowns.To check adequacy of the model, calculations of temperature on the inner surface of lining of the coke calcination furnace were carried out during the heating process.The analysis of the given graphs shows that the developed mathematical model is adequate.On average, difference between thermocouple readings and calculated values does not exceed 5%.Further use of the developed mathematical model will be to create a computational complex for evaluating temperature fields along the entire length of rotary kilns for calcining petroleum coke.
