Abstract

See full text

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/Nm3 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, wherein the fuel is combusted with an oxidant comprising at least 85% oxygen, and combustion gases are caused to be recirculated into the combustion zone and thereby dilute the mixture of fuel and oxidant therein sufficiently for the flame not to damage the refactory material.
