Description

Technical Field

[0001] The utility model relates to the technical field of industrial furnaces, and particularly relates to a burner brick for an industrial furnace. Background Technique

[0002] An industrial furnace is a device used for high-temperature treatment of materials, which is widely used in different industrial fields such as cement, ceramics, metal smelting, glass, etc. Its main function is to generate heat by burning fuel to reach the required high temperature, so as to heat, calcine, melt or perform other heat treatments on the materials. The burner brick is a refractory material specifically used in industrial furnaces, mainly used in the burner area with extremely high temperatures. Their design aims to withstand high temperatures, high pressures and the direct impact of flames on them, ensuring the safe and efficient operation of the furnace.

[0003] In existing industrial furnaces, an integral burner brick is usually adopted. This traditional burner brick is connected between bricks through adhesives or other filling materials. However, this connection method is too inconvenient during disassembly, assembly and maintenance. Moreover, when in a high-temperature environment for a long time, the adhesives and filling materials may deteriorate, resulting in the shedding and cracking of the adhesives, thereby reducing the working efficiency and product quality of the industrial furnace. For this reason, we propose a burner brick for an industrial furnace. Content of the Utility Model

[0004] The purpose of the utility model is to provide a burner brick for an industrial furnace to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A burner brick for an industrial furnace, including a burner brick body. The burner brick body is composed of a first brick body and a second brick body. Both the first brick body and the second brick body are composed of a wear-resistant outer shell, a heat-resistant layer and a heat-conducting layer. A heat-resistant layer is fixedly connected between the inner walls of the wear-resistant outer shell, and a heat-conducting layer is fixedly connected between the inner walls of the heat-resistant layer. Two T-shaped blocks are fixedly connected to one side of the first brick body, and two T-shaped grooves are opened on one side of the second brick body.

A second combustion chamber is opened on one side of the second brick body, and the second combustion chamber penetrates through the second brick body. The first combustion chamber is communicated with the second combustion chamber.
