ABSTRACT:
An apparatus for heating or heating and reduction raw material of a metallurgical furnace, utilizing high temperature waste gases which are released from the same furnace, has one or plural numbers of reactor(s) capable of holding the raw materials in the amount which can be charged in plural numbers of processing in the metallurgical furnace, where the reactor(s) is (are) disposed on a bypass passage connected to a pipe of a waste gas processing apparatus for cooling and scrubbing the waste gases from the metallurgical furnace. A part or all the waste gases are introduced into the reactor(s) and come into contact with the raw materials therein when the blowing in the furnace is performed to a full scale, and the reactor is cut off at the initial and final stage of blowing, whereby the heating or the heating and reduction raw material of a metallurgical furnace is effectively performed.
