    摘要： A method and apparatus for operating regenerative hot-blast stoves which are heated successively or alternately to supply the hot-blast required in blast furnaces. Each furnace is provided with a group of at least two hot-blast stoves which share a common cold air supply manifold and a common hot-blast pipe leading to the furnace. The stove which is ready to go on-wind is first filled with compressed air from a source independent of the cold air supply manifold and then is directed to the cold air supply manifolds. Each blast furnace stove is connected by a valve controlled filling connection to a common filling pipe communicating with an air tank connected to a blower.
