DEVICE TO ADJUST GAS TEMPERATURE IN MANIFOLD PIPELINE OF HOT GAS Russian patent published in 2014 - IPC C21B9/16 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy, in particular, to a device for adjustment of gas temperature in a manifold pipeline for supply of hot gas into a blast furnace. The device comprises a mixing reservoir with the first and second mixing chambers, which are hydrodynamically connected to each other by means of narrowing of a Venturi pipe type. The first mixing chamber is equipped with the first inlet window for supply of hot gas into the first mixing chamber, the second inlet window for supply of cold gas into the first mixing chamber and the third inlet window for supply of cold gas into the second mixing chamber. The first mixing chamber is also equipped with the first outlet window for supply of the first flow of mixed gas from the first mixing chamber into the first gas distribution system. The second mixing chamber is equipped with the second outlet window for supply of the second flow of mixed gas from the second mixing chamber into the second gas distribution system. The first flow of the mixed gas has temperature differing from the temperature of the second flow of mixed gas.

EFFECT: usage of the invention will make it possible to increase efficiency of a blast furnace.
