2023-07-20 16:22:06

Rotary waste incinerator is a kind of equipment used to treat solid waste, which is usually in an environment of high temperature, corrosion, and high thermal stress. To meet these stringent conditions, commonly used refractory brick materials include:

High alumina brick: High alumina brick is a refractory material whose main component is high-purity alumina. It has good heat resistance, wear resistance, and corrosion resistance, and is suitable for rotary waste incinerators in high-temperature environments.

Aluminum silicate brick: Aluminum silicate brick is a refractory material mainly composed of alumina and silica. It has high fire resistance and thermal shock stability and performs well in high-temperature environments.

Zirconium silicate brick: Zirconium silicate brick is a refractory material mainly composed of zirconia and silica. It has good fire resistance and corrosion resistance and can withstand high temperatures and corrosive gas.

Corundum mullite brick: Corundum mullite bricks are made of corundum and mullite as the main raw materials, by adding the appropriate amount of alumina, silica ultrafine powder, and additives, and firing at high temperatures in an oxidizing atmosphere. anti-oxidation. It is not easy to react with O2, H2, CO, and other gases.

Silicon carbide bricks: refractory bricks made of silicon carbide as the main raw material and the main crystal phase is silicon carbide. Silicon carbide bricks have excellent acid resistance, alkali resistance, wear resistance, high strength, high thermal shock resistance, small thermal expansion coefficient, and good thermal conductivity.

These refractory bricks are widely used in rotary waste incinerators and can withstand the challenges of high temperatures, chemical attacks, and thermal stress. When selecting specific refractory bricks, comprehensive consideration should be made according to specific process parameters, waste components, and engineering requirements, and relevant standards and guidelines should be followed. It is recommended to consult relevant refractory material engineers or manufacturers to obtain more accurate and personalized suggestions.
