PURPOSE: A device for blowing moisture in electric kiln is provided to improve durability by fixing tuyere made of alumina onto body and cover of the electric kiln, thereby suppressing damage of firebricks or deformation of ceramic board during transferring of heat into the electric kiln. CONSTITUTION: In an electric kiln comprising a coil shaped hot wire that is installed inside the body equipped with a heating chamber, and a cover for cutting off flowing out of heat generated from the hot wire to the outside, the device for blowing moisture in the electric kiln is characterized in that a plural inserting holes are formed on the lower part of one side of the body and a cover of the electric kiln respectively, the inserting holes formed on the body are formed between the wall surface and the bottom surface, and a tuyere(50) made of alumina or mullite capable of blowing moisture is coupled to the respective inserting holes, wherein the tuyere(50) comprises a cylindrical body(51) on upper and lower parts of which male screw thread(51b) is formed, and in the center of which a blowing hole(51a) is formed; fixed members(52) on the inner circumferential surface of which a female screw thread(52a) to be coupled to the male screw thread(51b) of the body(51) is formed so that the body(51) is fixed to the cover and body of the electric kiln; and a cap(53) which is inserted into the blowing hole(51a) of the body(51) to cut off and emit heat generated from the heating chamber.
