How to Choose Refractory Materials for the Burning Method of Garbage Fuel in the Furnace

There are several main ways to burn garbage fuel. Today we mainly introduce solid bed combustion and fluidized bed combustion. For different combustion methods, different types of refractory materials need to be selected.

Solid bed combustion: During the solid bed combustion process of garbage, the fuel presents a static state in the furnace. This combustion method requires selecting refractory materials that can withstand high temperatures, and resist corrosion and wear, such as high-alumina refractory bricks, magnesia-aluminum refractory materials, silicon carbide ceramic materials, etc.

Fluidized bed combustion: During the waste fluidized bed combustion process, the fuel is suspended in the furnace by the airflow and moves with the airflow. This combustion method requires selecting refractory materials that are resistant to wear, corrosion, and high temperature, such as high-aluminum refractory bricks, potassium aluminosilicate refractory materials, etc.

In addition, factors such as the chemical composition, physical properties, and moisture content of waste fuel also need to be considered when selecting refractory materials. For example, if the garbage fuel contains high concentrations of elements such as sulfur and chlorine, you need to choose refractory materials with good corrosion resistance. If the moisture content of the waste fuel is high, refractory materials with good temperature resistance and wear resistance need to be selected.

To sum up, selecting appropriate refractory materials requires comprehensive consideration based on many factors such as the combustion method, chemical composition, and physical properties of waste fuel. During use, it is also necessary to regularly inspect and maintain the refractory materials and replace damaged parts in time to ensure the stable operation of the waste fuel boiler.
