    Abstract: A method for reducing nitrogen oxide(s) and carbon monoxide from flue gases of an industrial burner adapted to burn gaseous and/or liquid fuel is disclosed. The burner comprises burner automation containing measuring instruments, and a mixing zone accompanied by a combustion chamber. The burner automation is in communication with measurement instruments of flue gas conduit. The combustion chamber or flue gas conduit has two catalytic zones of at least one three-way catalytic converter(s). The catalytic zones are successive in progressing direction of flue gases. An inlet flow (QI, QItot) of combustion air and an inlet flow (QPA, QPAtot) of fuel is delivered into the mixing zone. The flue gases are generated in the combustion chamber by combusting air and fuel delivered into the mixing zone. The amount of residual oxygen is measured in flue gases by a lambda-sensor. The flue gases are directed to at least one three-way catalytic converter(s). The inlet flow (QI, QItot) of combustion air and the inlet flow (QPA, QPAtot) of fuel arriving in the mixing zone is adjusted by the burner automation, so that the mean amount of residual oxygen in moles compared to mean amount of carbon monoxide in moles, is 0.5/1 (mole/mole) and O2 within the range of 0.01-0.50 vol-% in flue gases prior to or at the first catalytic zone of the at least one three-way converter. Supplementary air is delivered between the first and the second catalytic zones of the three-way converter or between catalytic zones of two successive three-way catalytic converters, so that concentration in the flue gases after said catalytic zones is within range of 0-9 ppm for NOx and within a range of 0-100 ppm.

    Abstract: The invention relates to a method for the controlled operation of an industrial oven which is heated in a regenerative manner and which comprises an oven chamber, in particular a melting tank, in particular for glass, having the following steps: injecting fuel into the oven chamber via at least one fuel injector, which is designed to inject fuel, practically without combustion air in particular, conducting combustion air to the oven chamber in a first period duration and conducting exhaust gas (AG) out of the oven chamber in a second period duration separately from the fuel in a periodically alternating manner by means of a left regenerator and right regenerator which are associated with the at least one fuel injector and which are designed to regeneratively store heat from the exhaust gas and transmit heat to the combustion air. A supply of the combustion air is automatically controlled by means of a control loop. The control loop takes into account an excess air coefficient that is specified in the method as well as the location of the entrance of the excess air upstream, in, or downstream of the air-side regenerator. A corresponding control device and an industrial oven which comprises such a control device and which is heated in a regenerative manner are likewise claimed.
