The paper presents the results of the tests performed on a semi industrial scale regenerative gas burner. The tests were performed on a gas burner fitted with four regenerative beds built into the burner. The beds generated the exhaust-to-air energy transfer intensity sufficient to obtain the efficiency of the furnace charge preheating process of at least 70%. The paper presents the influence of various operating parameters of the burner on the combustion process (particularly the emission of nitric oxides) such as air excess coefficient λ , operating time of the regenerators and combustion chamber operating temperature. liven in the least advantageous conditions when the air is preheated to reach the temperature above 1000°C - less than 100 K lower than the temperature of the combustion chamber- the NOx emission did not exceed 100 ppm.
