Problems solved by technology

Due to the large number of burners arranged, it has a good effect in improving the efficiency and quality of molten glass melting. increase, it is very easy to appear the phenomenon of material running and material line instability (such as figure 1 shown), that is, part of the batch material will flow with the glass liquid on the upper part of the liquid surface in the kiln corresponding between the burners, forming figure 1 The "ridge"-like material running phenomenon marked in A makes the batch material not completely melted
Due to the limitation of the kiln structure and process layout, it is difficult to solve this problem by increasing the number of burners; and if the flow rate of the burners is increased for strong melting, the effective coverage area of ​​the flame has not yet increased, and the "ridge" shape cannot be effectively solved. The material phenomenon will also form an impact on the batch material and the glass liquid surface, causing a large amount of powder to fly. At the same time, it will also affect the temperature rise of the local position in the high-temperature melting area, resulting in a drastic change in the local temperature in the kiln, resulting in thermal shock and affecting the kiln.

Abstract

The invention discloses a rotary combustion device, a kiln and a rotary combustion method of the kiln. The rotary combustion device is used for being mounted at the top of the kiln and comprises a mounting base, an adjusting arm and a tubular combustor; the mounting base and the adjusting arm are both fixed to the top of the kiln, the middle of the tubular combustor is rotatably connected with the mounting base; the output end of the tubular combustor is positioned in the kiln; and the output end of the adjusting arm is connected with the middle part of the tubular combustor. According to the scheme, rotation or swing adjustment of the tubular combustor is achieved through the adjusting arm and a knuckle bearing, dynamic heating of materials in the kiln is achieved, and the fire passing coverage area of the single tubular combustor is increased; and by controlling and adjusting the rotation period and the rotation angle of the tubular combustor, targeted combustion is carried out on refractory materials, agglomerated materials and running materials, the material line of the materials is effectively stabilized, the melting quality of the kiln is guaranteed, and the melting rate of the kiln is greatly improved.

Description

technical field [0001] The present disclosure relates to the technical field of kiln combustion, in particular to a rotary combustion device, a kiln and a rotary combustion method thereof. Background technique [0002] In the melting process of molten glass, pure oxygen top firing technology has been gradually popularized due to many advantages such as complete combustion, high flame temperature, significant reduction of NOx emissions, stable process, energy saving, improvement of finished product quality and overall benefit. application. Practice has shown that the structural arrangement of the combustion device is the core of the pure oxygen top firing technology. The reasonable arrangement of the combustion device can ensure that the flame can effectively cover the glass liquid surface, improve the melting quality of the glass liquid, stabilize the material line, and reduce the loss of material. [0003] In glass fiber production enterprises, the layout and design of pur...
