Extension-type tunnel kiln combustor and method thereof

Abstract

Provided are an extension-type tunnel kiln combustor and a method of the extension-type tunnel kiln combustor. The problem that a combustion device in tunnel kiln sintering can not be moved is resolved. The extension-type tunnel kiln combustor structurally comprises a cylindrical telescopic gas pipe 5, wherein a gas burner 6 is arranged at the front end socket of the telescopic gas pipe 5, a gas port 16 is arranged at the back end socket of the telescopic gas pipe 5, a telescopic air pipe 3 is arranged on the front section of the telescopic gas pipe 5 in a sleeved mode, a fixing support 4 is arranged at the front end between the telescopic air pipe 3 and the telescopic gas pipe 5, a flange plate 9 arranged at the tail end of the telescopic air pipe 3 and a connecting plate 8 arranged on the telescopic gas pipe 5 are fixedly connected through flange plate screws 11, an air pipe 2 is arranged outside the telescopic air pipe 3 in a sleeved mode, two groups of sealing cushions 15 are arranged between the air pipe 2 and the telescopic air pipe 3, an air inlet 13 is arranged between the two groups of the sealing cushions 15 of the telescopic air pipe 3, an air port 14 is arranged in the middle back portion of the air pipe 2, and a kiln fire scanning port 7 is arranged in the connecting plate 8. The extension-type tunnel kiln combustor has the advantages that the combustion device can be moved, and the extension-type tunnel kiln combustor is energy-saving and efficient, and is applied to combustion application of refractory matter tunnel kilns.

Description

Technical field: [0001] The invention specifically relates to a telescopic tunnel kiln burner and a method thereof, which belong to the technical field of combustion of refractory material tunnel kilns and are suitable for the combustion application of refractory material tunnel kilns. Background technique: [0002] As far as the inventor knows, the tunnel kiln combustion devices used in the sintering of refractory materials are all installed in a fixed position 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 defor...

AI Technical Summary

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
