Refractory Materials Used in Various Parts of Fluidized Furnaces

The fluidized furnace is a special industrial furnace. Its working principle is to mix materials and gas at high temperatures and form a gas-solid two-phase flow in the furnace, so as to achieve the technical purposes of drying, pyrolysis, and calcination. In order to ensure the normal operation of the fluidized furnace, various parts need to use different types of refractory materials. The following is an introduction to the refractory materials used in various parts of the fluidized furnace.

Furnace: The furnace is the core part of the fluidized furnace, and the refractory materials used in it need to have the characteristics of high refractoriness, high corrosion resistance, and high mechanical strength. Commonly used refractory materials include high alumina, silicate, and silicon carbide. Among them, high-alumina refractories have the characteristics of high refractoriness, high mechanical strength, and high thermal stability, and are one of the commonly used furnace materials.

Dispersion plate: The dispersion plate is an important part of the fluidized furnace, and the refractory material used in it needs to have good wear resistance and heat resistance. Commonly used refractory materials include high alumina and silicon carbide.

Nozzle: The nozzle is the key part of gas injection and gas supply in the fluidized furnace, and the refractory material used in it needs to have high heat resistance and high wear resistance. Commonly used refractory materials include silicon carbide and zirconia.

Pipeline: The pipe is the main channel for gas and material transportation in the fluidized furnace, and the refractory materials used in it need to have high heat resistance and high corrosion resistance. Commonly used refractory materials include silicate and alumina.

Discharge port: The discharge port is the outlet of the material in the fluidized furnace, and the refractory material used in it needs to have high heat resistance and good wear resistance. Commonly used refractory materials include high alumina and alumina.

Cooling wall: The cooling wall is a key part of the fluidized furnace, and the refractory materials used in it need to have high heat resistance and high corrosion resistance. Commonly used refractory materials include silicon carbide and high alumina.

The refractories used in each part of the fluidized furnace need to be selected according to their different working environments and characteristics. At the same time, the selection of refractory materials also needs to consider factors such as its cost performance and reliability. With the continuous development of technology, more new refractory materials will also be applied to fluidized furnaces to provide strong support for the operation of fluidized furnaces.
