The modern level of the development of computer engineering and software allows to simulate the processes with different degree of complication and to solve the problems connected with aerodynamic features of turbulent flows of withdrawn gases both in entrance and exit of coke batteries. The paper presents the results of aerodynamic simulation of gas medium using Ansys program in order to determine the temperature field above the surface of coke battery chimney shaft, as well as the results of registration of speed of withdrawn gases for adjusting the flame level. Realization of operation of continuous monitoring systems directly on chimney shaft makes it possible to control thermal state of a coke battery in general and provides lowering of harmful emissions in the atmosphere.
