Problems solved by technology

[0003] As far as the inventor knows, the current domestic combustion device used in the sintering process of refractory materials is diffusion combustion, and the commonly used diffusion combustion has several disadvantages in the combustion while the auxiliary gas and gas are mixed; Cause excess combustion gas, increase the temperature of the exhaust gas and increase the heat loss of the kiln
Second, due to poor mixing, the gas cannot be fully combusted, resulting in excess fuel, thus wasting fuel
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

Abstract

Provided are a mechanical adjusting premixing type secondary fuel gas nozzle and a method. An end cap 17 is arranged at the front end of a fuel gas pipe 22, and a plurality of fuel gas outlets 18 are formed in the end, close to the end cap 17, of the front end of the fuel gas pipe 22. The front end of an air inlet pipe 19 is in fastened connection with the tail end of a connecting bend 16. The front end of the connecting bend 16 is in fastened connection with the tail end of a mixing pipe 9. A fuel gas nozzle body 11 is arranged at the front end of the mixing pipe 9, and a connecting disc-a 14 is arranged at the end, close to the tail end, of the mixing pipe. A fire observation hole 15 is formed in the connecting disc-a 14. A main air opening 6 is formed in the end, close to a flange plate-a 13, of an air pipe 5, and a kiln slideway 2 is arranged on the outer side of the air pipe 5 in a sleeving manner. The kiln slideway 2 is connected with a kiln wall 1 through a connecting steel plate 4 fixed to the tail end and an expansion bolt 3. A rack 27 is arranged at the rear end of the air pipe 5, and is provided with a gear 29 in a male-female manner.

Description

[0001] This application is a divisional application of the invention patent application with application number: 2013100601935, invention name: mechanical adjustment premixed secondary gas burner and method, and application date: February 17, 2013. technical field [0002] The invention specifically relates to a mechanically regulated premixed secondary gas burner and a method thereof, which belong to the technical field of kiln combustion and are suitable for the combustion application of refractory materials. Background technique [0003] As far as the inventor knows, the combustion device used in the sintering process of refractory materials in China is diffusion combustion, and the commonly used diffusion combustion is that the gas-supporting gas and the gas are mixed while burning, and there are several disadvantages; It causes excess gas-supporting gas, increases the temperature of the exhaust gas, and increases the heat loss of the kiln. The second is that the gas can...
