DEVICE FOR INJECTING GAS INTO RESERVOIR Russian patent published in 2011 - IPC F27D7/00 C21B11/00 C21B13/00 

FIELD: machine building.

SUBSTANCE: device for injecting gas into metallurgical reservoir consists of channel for gas flow passing from back end to front end, of passages for cooling water supply and drain formed with three concentric tubes and of circular hollow head of gas flow channel at front end of channel with passage for cooling water connected with passages for cooling water supply and drain. The channel head includes a hollow shell and a dividing device positioned inside the shell; the dividing device consists of a dividing ring and of multitude of circular lugs. The lugs project outside from central part of the dividing end to the shell and form passages for cooling water in form of a row of circular galleries for water flow each running along circumference of the channel for gas flow and which are interconnected for water flow successively via the galleries from the passage for supply of cooling water to the passage for return of the cooling water. Also, there are partitions installed between the dividing device and the said shell to make ends of galleries for water flow and orifices in the said lugs forcing water flow successively along galleries.

EFFECT: raised strength of structure and improved cooling.
