(57) To more effectively denitrify a cement-kiln discharge gas in an RSP-type burning device for IC cement. [Solution] A burning device 1 for cement comprises: a rotary kiln 2; a mixing chamber 4 disposed between the rotary kiln and a lowermost cyclone; a flash- and swirl-type calciner 3 disposed between the mixing chamber and a M second-lowest preheater cyclone; a clinker cooler 6 for cooling a cement clinker discharged from the rotary kiln; and a cl gas duct 7a for introducing a discharge gas G2 from the clinker cooler into a region located after the outlet of the mixing.
