Abstract: A method for continuous firing of combustion chambers with at least three regenerative burners, wherein a first regenerative burner cyclically in the combustion mode conveys supply air and a second regenerative burner in the exhaust mode conveys exhaust air. To avoid escape of hazardous process gases from the combustion chamber into the environment and high carbon monoxide emissions, and to provide energy-efficient firing operation despite use of compact regenerators, the volume flow of the supply or exhaust air through the first or second regenerative burner is reduced continuously and in counter-cycle mode to the volume flow of supply or exhaust air through a third regenerative burner at constant combustion chamber pressure until the first or second regenerative burner is flow-free.
