The utility model relates to an energy saving and emission reduction's bottom blowing stove. The utility model discloses the problem of stirring process power consumption among the prior art, inefficiency aims at solving. The furnace body bottom of bottom blowing stove is equipped with oxygen rifle and gas diffluence pipe, the export of the entry linkage oxygen rifle of gas diffluence pipe, the gas diffluence pipe is including the airflow outlet of some. The utility model has the advantages of improve gas outlet to the oxygen rifle, breaks the whole up into parts, simultaneously, the stirring at no dead angle had both been guaranteed to the position of reasonable distribution gas outlet, the direction of the stirring in -process air current that has complicated again, the stirring effect of improvement, the total is convenient for wash, is maintained and is adjusted, and especially threaded connection can twist reverse the gas diffluence pipe to a certain extent to adjust the the most favorable angle of production efficiency in real time.
