<p>A method for heating a blast furnace stove by combusting in a stable, visible flame a fuel with a lower heating value (LHV) of 9 MJ/Nm 3 or less in a combustion region, arranged in a combustion chamber in the stove, and causing the combustion gases to flow through and thereby heat refractory material in the stove. The invention is characterized in that combusted with an oxidant comprising at least 85% oxygen, and combustion gases are caused to be recirculated into the combustion zone and thereby diluting the mixture of fuel and oxidant therein sufficiently for the flame not to damage the refactory material.</p> |
