The gas burner is a device which the main aim is delivering the right number of gas fuel and oxidizing agent and it also has to ensure flame stabilization. The difficult controlling problem appears when the modern and compact high temperature regenerative burners are used. The controlling difficulties in those systems are related to the large number of burners and a periodic change (with high frequency) of temperature field which depends on such parameter as reversion time. The knowledge of the dynamic and static regenerator characteristics makes easier the programming of automatic control and regulation process and helps in creating the new regenerator filling construction in order to improve the heat transfer intensification and the furnaces efficiency. Based on research results the paper presents the selected data research dealing with the dynamic and static regenerator characteristic. The measurement of quick-changing fluctuating thermal field and the way of the temperature sensors selection have been indicated. The regenerator starting state and pseudo-steady state characteristics have also been presented. Finally the qualities of the regenerator and the economic income have been expressed.
