The design of the individual components of the systems with lances for high-temperature reactors significantly influences their proper functioning and the course of the technological process on which the quality of the resulting product depends. The lance systems intended for the high-temperature reactors are designed for gas blowing of various, especially gaseous media. From their proper functioning, they are probably the most critical elements through which the medium is directly blown to the reactor workspace, i.e. the lances. The lances provide the required parameters of the blown medium directly in the reactor working area and thus the correct course of the ongoing technological process. For the correct operation of the lances, it is important not only to comply with the required parameters of the supplied medium but above all pay attention to the design of the lance itself (the blowing element), which ensures the required parameters and functions of the lance. As for the dimensions of the lances, we are able to design these based on calculation relationships that are based on the fluid flows and their relations. However, feedback is very important for designers, i.e. verifying whether the designed lance works as the designer intended it to work. From this point of view, the designers are helped by experimental research, in which it is possible to visualize these lance outflows and, if necessary, measure the assessing quantities of currents outflowing from the lances. This paper focuses on the possibilities to analyse the structure of gas outflow jet employing the gas flow visualization.Keywords: Gas blowing, lance outflows, lance, gas flow visualization
