Abstract

The invention relates to a method for the controlled operation of a regeneratively heated industrial furnace (100), comprising a furnace chamber (10), preferably for controlling the fuel energy supplied to the furnace chamber (10) for a fuel of varying calorific value, comprising the steps of: - injecting fuel into the furnace chamber (10) by way of at least one fuel injector (20, 20'), which is designed for the injection of fuel, in particular virtually without any combustion air, - periodically alternating conduction of on the one hand combustion air to the furnace chamber (10) in a first period phase and on the other hand exhaust gas (EG) from the furnace chamber (10) in a second period phase, separately from the fuel, wherein - a supply of the combustion air or such like oxidizing agent is set and a residual amount of oxygen in the exhaust gas is determined. It is provided according to the invention that - an oxygen consumption of the supplied combustion air and the residual oxygen that is converted in the combustion of the fuel is determined and - the oxygen consumption is used as a measure of an amount of fuel energy that is used, wherein a stream of fuel for injection is set in such a way that the oxygen consumption is controlled to a predetermined value of the oxygen consumption.
