A method for operating a regenerative heater including a first chamber and a second chamber, the first chamber having a burner arranged therein, the second chamber having heat storage means; the method including: a heating cycle where fuel and oxidizing gas are fed to the burner of the first chamber and allowed to burn and where hot flue gasses are led through the second chamber to heat the heat storage means; and a blowing cycle where a process gas is fed through the second chamber to pick up heat from the heat storage means where the heating cycle includes the following steps: feeding a first stream of fuel to the burner of the regenerative heater; feeding a second stream of fuel to a pre-combustion chamber; feeding oxygen to the pre-combustion chamber; allowing the second stream of fuel and the oxygen to interact so as to form oxidizing gas; feeding the oxidizing gas to the burner of the regenerative heater, where, at the end of the heating cycle, the supply of oxygen to the pre-combustion chamber is discontinued, while further feeding the second stream of fuel to the pre-combustion chamber and further feeding the first stream of fuel to the burner. |
