PURPOSE: An apparatus for changing a diameter of the supplying nozzle of the raw gas is provided to simultaneously solve problems such as the danger of the gas poisoning collaterally occurring according to the replacement of nozzles, the delay of the replacement operation and the clogging of the nozzles by possessing nozzles having various sorts of diameters so that the nozzle can be promptly changed depending on the operation conditions. CONSTITUTION: The apparatus comprises a discoid base (130) one surface of which is opened, wherein the base has a supplying port (132) connectable to a channel of C.O.G (coke oven gas), a flexible hose (10), and fixed to the front of a lance nozzle of a lime calcining furnace; a nozzle plate (120) rotationally installed inside the base (130), wherein the nozzle plate has a quadrangle shaped axial hole (114b) in the center thereof, and formed in such a manner that nozzle inserting holes (121) in which a plurality of nozzles (70) having different diameters are fixed by penetrating the both surfaces of thereof along a circumferential direction thereof are conformable with the supplying port (132) during the revolution; a cover (110) in the center of which an axial hole (114a) is penetrated and formed, wherein the cover closes the opened surface of the base and is fixed so that the nozzle plate is not deviated, and the cover is equipped with a connecting pipe (111) which is connected to the supplying port, any one of the nozzle inserting holes and a lance nozzle of the calcining furnace at one surface part thereof; and an adjusting member (200) which is inserted into the axial hole of the cover, and one end of which is coupled to the axial hole of the nozzle plate so that the nozzle plate can be rotated.
