Abstract: A method includes the introduction of a first medium into the compartment through an inlet and the heating of the first medium when it is present in the inlet. The heating takes place through the use of a combustion arrangement that is arranged in the inlet and that comprises fuel. The heating, the use of the combustion arrangement, includes in turn the ignition of the fuel, combustion of the fuel, and the transfer of the combustion heat to the first medium that is present at the combustion arrangement in the inlet. The combustion arrangement, is arranged in a region in the inlet, which in turn is arranged outside of the direct passage of the first medium in and through the inlet, such that the ignition of the fuel, the combustion of the fuel and the transfer of combustion heat to the first medium take place in this region.

Abstract: A method during the oxidation and sintering of pellets includes the introduction of a first medium into the compartment through an inlet connected to the compartment and the heating of the first medium in the inlet through the use of a combustion arrangement. The use of the combustion arrangement includes the ignition of the fuel, combustion of the fuel, and the transfer of the combustion heat to the first medium that is present at the combustion arrangement. A second medium is introduced to the inlet through an intake in the direct vicinity of the combustion arrangement, where the ignition of the fuel and the combustion of the fuel take place for the transfer of combustion heat also to the second medium. The heated first medium and the heated second medium are mixed before or during their introduction into the compartment.

Abstract: A method for the oxidation and sintering of pellets includes the introduction of a first medium into a compartment through an inlet connected to the compartment and the heating of the medium in the inlet through the use of a combustion arrangement. The use of the combustion arrangement includes the ignition of the fuel, the combustion of the fuel, and the transfer of combustion heat to the first medium that is present at the combustion arrangement. In a region in the inlet outside the direct passage of the first medium, the ignition of the fuel, the combustion of the fuel and the transfer of combustion heat to the first medium take place. By the introduction of a second medium into the region in the direct vicinity of the combustion arrangement, the combustion of the fuel and the transfer of combustion heat also to the second medium take place.

Abstract: This invention concerns a method for the heating of a medium in a compartment 1 in which pellets 2 are arranged to be oxidised and sintered with the aid of the hot medium. The method comprises the introduction of a first medium 3 into the compartment 1 through an inlet 4 and the heating of the first medium 3 when it is present in the inlet 4. The heating takes place through the use of a combustion arrangement 5, or a part of such an arrangement, that is arranged in the inlet 4 and that comprises fuel. The heating, the use of the combustion arrangement 5, comprises in turn the ignition of the fuel, combustion of the fuel whereby combustion heat is developed, and the transfer of the combustion heat to the first medium 3 that is present at the combustion arrangement 5 in the inlet 4.

Abstract: This invention concerns a method for the oxidation and sintering of pellets 1 arranged in a compartment 2 in which the oxidation and sintering take place with the aid of a medium with a defined temperature, which medium heats the pellets 1. The method comprises the introduction of a first medium 3 into the compartment through an inlet 4 connected to the compartment 2 and the heating of the medium in the inlet through the use of a combustion arrangement 5, or a part of a combustion arrangement, arranged in the inlet 4 and comprising fuel where the use of the combustion arrangement 5 comprises the ignition of the fuel, the combustion of the fuel whereby combustion heat is developed, and the transfer of combustion heat to the first medium 3 that is present at the combustion arrangement 5.

Abstract: This invention concerns a method during the oxidation and sintering of pellets (1) arranged in a compartment (2) in which the sintering takes place with the aid of a medium with a high temperature, which medium heats the pellets (1). The method comprises the introduction of a first medium (3) into the compartment (2) through an inlet (4) connected to the compartment (2) and the heating of the first medium (3) in the inlet (4) through the use of a combustion arrangement (5), or a part of a combustion arrangement, arranged in the inlet (4) and comprising fuel. The use of the combustion arrangement (5) comprises the ignition of the fuel, combustion of the fuel whereby combustion heat is developed, and the transfer of the combustion heat to the first medium (3) that is present at the combustion arrangement (5).
