Mechanical adjustment premix type gas burner and method

Abstract

The invention provides a mechanical adjustment premix type gas burner and method. A plug 17 is arranged at the front end of a gas pipe 19. Multiple gas outlets 18 are formed in the end, close to the plug 17, of the front end of the gas pipe 19. A second fixed support 9 is arranged at the position, close to the gas outlet 18, of the gas pipe 19. A connection disc b21 is arranged at one end of the tail end of the gas pipe 19. A gas burner body 7 is arranged at the front end of a mixing pipe 16. A first fixed support 5 is arranged at the end, close to the gas burner body 7, of the mixing pipe 16. An auxiliary wind opening 15 is formed in the end, close to a flange plate b22, of the mixing pipe 16. A connection disc a12 is arranged at the end, close to the auxiliary wind opening 15, of the mixing pipe 16. A main wind opening 4 is formed in the end, close to a flange plate a13, of an adjustable air pipe 3. The front section of the adjustable air pipe 3 is sleeved with an air pipe 2. The air pipe 2 is fixed to a kiln wall 1 through expansion bolts 23 by means of a fastening steel plate 24 fixedly arranged on the tail section.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 2013100465748, the invention name: mechanical adjustment premixed gas burner and method, and the application date: January 24, 2013. Technical field: [0002] The invention specifically relates to a mechanically regulated premixed 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 cannot be ...

AI Technical Summary

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
