<p>The present invention relates to an apparatus for raising the temperature of a refractory including a dry fire extinguishing system, a steam supply unit, and a moisture removing unit, in which the system has a main body where a container is arranged, a boiler, and a gas circulation device with a gas circulation path including the container being provided therein, external steam is supplied to the steam supply unit to be radiated in the boiler, and a working gas is circulated in the gas circulation path so as to raise the temperature of the refractory formed in the container and a charging material charged in the container. The temperature of the refractory is gradually raised by controlling the pressure of the steam which is supplied to the steam supply unit, and the moisture that is generated by the refractory in the main body is rapidly discharged out of the main body by using the moisture removing unit.</p> |
