Method for heating a blast furnace stove (500) by combusting a fuel with a lower heating value (LHV) of 9 MJ/Nmor less in a combustion zone, arranged in a combustion chamber (301;401;501;601)in the stove, and causing the combustion gases to flow through and thereby heat refractory material (502) in the stove. The invention is characterized in that the fuel is combusted with an oxidant comprising at least 85 % oxygen, and in that combustion gases are caused to be recirculaled into the combustion zone and thereby diluting the mixture of fuel and oxidant therein sufficiently for the combustion to be flameless. |
