The invention discloses a novel energy-saving kiln. The novel energy-saving kiln comprises a kiln wall body, burner supports are arranged in the kiln wall body at equal distances, burners for sprayingfire into the interior of a kiln body are arranged on the burner supports, polycrystalline cotton layers are arranged at one ends, facing the interior of the kiln, of the burner supports, zircon-containing cotton layers and common asbestos layers are sequentially arranged at one ends, far away from the interior of the kiln, of the burner supports, the upper end of the kiln wall body is provided with a kiln roof, the top of the kiln roof is sequentially provided with a polycrystalline cotton layer, a ceiling framework, a zircon-containing cotton layer and a common asbestos layer from bottom totop, a kiln car running in the length direction of the kiln body is arranged in the kiln, the upper surface of the kiln car is sequentially provided with the common asbestos layer, the zircon-containing cotton layer and the polycrystalline cotton layer. According to the novel energy-saving kiln, the burner supports are installed in an asbestos wall body, an air curtain sealing technology is adopted on the contact surface between a wall body of a sintering belt and the kiln car, the technical problem encountered in the installation of the whole asbestos kiln body is solved, and the energy-saving level of the kiln is greatly improved.
