Hazardous waste
Industry ChallengesThe atmosphere inside waste (hazardous waste) incinerators is complex, characterized by alternating acidic and alkaline gas corrosion and severe temperature fluctuations. Rotary hazardous waste incinerators, in particular, place extremely high demands on the corrosion resistance and thermal shock stability of refractory materials when processing waste that causes severe acidic or alkaline corrosion. Conventional products struggle to meet the requirements for long-term continuous operation.
Huawei Refractories supplies specialized refractory materials for waste (including hazardous waste) incineration furnaces; these products are suitable for critical components such as rotary kiln hazardous waste incinerators and secondary combustion chambers.
Huawei’s chrome-corundum bricks are manufactured using corundum and chromium oxide as primary raw materials, enhanced with nanocomposites through a specialized process, resulting in a stable, dense microstructure at high temperatures. Chrome-zirconia-corundum bricks build upon this foundation by incorporating zirconium oxide; at high temperatures, they form closed micropores and micro-cracks, providing excellent structural elasticity—making them particularly well-suited for rotary hazardous waste incinerators subject to severe acid and alkali corrosion.
In addition, we offer a comprehensive product range that includes high-purity corundum-mullite bricks (for secondary combustion chamber linings), silicon carbide bricks (for side walls), specialty wear-resistant bricks, and various castables.
