Problems solved by technology
The working method of the burner on the existing design combustion device is to sinter by the external flame under the condition of heat radiation, and at the same time, the highest temperature part is not on the sintered object on the kiln wall, and part of the heat energy is transferred by the inner kiln wall and the sintered object through radiation. It is not directly sintered by flame, so in the actual operation, the fire outlet of the kiln wall is particularly deformed due to sintering. In addition, the temperature inside the kiln wall is higher than the temperature of the sintered object, which is a waste of fuel

Description
Technical field: [0001] The invention specifically relates to a tunnel kiln rotary kiln combustion device, belongs to the technical field of combustion of refractory material tunnel kilns, and is suitable for the combustion application of refractory material tunnel kilns. Background technique: [0002] As far as the inventor knows, the combustion devices used in the sintering process of refractory materials in China are all installed in fixed positions at present. The sinter is just farther away. The working method of the burner on the existing design combustion device is to sinter by the external flame under the condition of heat radiation, and at the same time, the highest temperature part is not on the sintered object on the kiln wall, and part of the heat energy is transferred by the inner kiln wall and the sintered object through radiation. It is not directly sintered by flame, so in the actual operation, the fire outlet of the kiln wall is particularly deformed due to...
