Overview of industrial equipment and its refractory applications

High temperature industrial equipment is widely used in manufacturing and service industries. Its working environment is complex and the temperature is extremely high, often between 1000-1300℃. Therefore, refractory materials are key elements in these fields. It is particularly important to choose the right refractory bricks according to the needs of different parts. This article will introduce the application of refractory materials in high temperature industrial equipment in detail.

1. Equipment top and door area

The top and door areas of the equipment need to be insulated and lightened. Clay bricks and insulation bricks are usually used. Clay bricks have good thermal stability, while insulation bricks are effective in insulation. In addition, cordierite bricks are used to improve the heat resistance and wear resistance of the door.

2. Combustion chamber and main production room

The combustion chamber and main production chamber are the core high-temperature areas of the equipment, with temperatures reaching 1300°C. Refractory bricks are required to have good wear resistance, pressure resistance and thermal shock stability, and silica bricks are commonly used. High-alumina bricks are mainly used in the furnace head of the combustion chamber and the bottom of the carbonization chamber.

3. Heat recovery area

The heat recovery area is used to preheat the air or gas required for combustion. Due to the drastic temperature changes, refractory bricks with good thermal shock resistance are required, and clay bricks and insulation bricks are usually used.

4. Ramp area

The working temperature of the ramp area is between 1000-1200℃, connecting the vertical fire channel of the combustion chamber with the heat recovery area. Silica bricks are the main choice.

5. Exhaust system

The exhaust system includes flues and chimneys, and usually has an operating temperature of over 1000°C. It is necessary to select refractory bricks that are resistant to scouring, high temperature and corrosion. Commonly used materials include silica bricks and clay bricks.

The importance of refractory materials in high temperature industrial equipment

Different parts of high-temperature industrial equipment require refractory bricks with different characteristics, such as high-alumina bricks, silica bricks, clay bricks, insulation bricks and cordierite bricks. Choosing the right materials ensures the performance and life of the equipment and guarantees production efficiency. Reasonable design and selection of refractory bricks are essential for the long-term operation of the equipment.

in conclusion

Different parts of high-temperature industrial equipment have different functional requirements. Choosing the right refractory material can effectively improve the stability and life of the equipment. With the development of technology, the requirements for refractory materials will continue to increase, which will safeguard high-temperature production.
