Refractory Castable
Our Refractory Castable for Incinerator is a high-performance, high-temperature-resistant material specifically engineered for the harsh working environment of various incinerators (solid waste incinerators, hazardous waste incinerators, garbage incinerators, medical waste incinerators, and industrial waste incinerators). Developed with advanced material formulation, precision mixing, and on-site pouring construction technology, it integrates exceptional high-temperature resistance, corrosion resistance, thermal shock resistance, and wear resistance. As a core lining material for incinerator chambers, flue gas channels, and combustion zones, it effectively protects the incinerator shell, extends equipment service life, and ensures stable, efficient operation of the incineration system. Fully compliant with global industrial and environmental standards, including ISO 10081-1:2018, ASTM C133-17, EU Waste Incineration Directive (2000/76/EC), and US EPA 40 CFR Part 264, it is widely applied in incineration projects worldwide.

Unlike ordinary refractory materials that suffer from short service life, easy cracking, and poor corrosion resistance in incinerator environments, our incinerator-specific refractory castable is tailored to address the core pain points of incineration working conditions—high-temperature fluctuations (600–1300℃), severe erosion from acidic/alkaline flue gas (SO₂, NOₓ, HCl), scouring from high-speed dust and solid waste particles, and frequent thermal shocks. Its optimized material composition (high-alumina, corundum, mullite, or special anti-corrosion additives) ensures stable performance under extreme conditions, effectively solving industry issues such as lining peeling, cracking, and premature damage. It is an indispensable core material for efficient, safe, and compliant operation of incinerators in global environmental protection and waste treatment fields.

Product Feature
Core Working Principle & Application Scenarios in Incinerators
Our Refractory Castable for Incinerator acts as a thermal insulation and protective barrier for incinerator equipment, relying on its excellent material properties to resist high temperatures, corrosion, and wear, while isolating the high-temperature internal environment from the metal shell. It is designed to adapt to the different working conditions of various incinerator components, ensuring comprehensive protection and stable operation:
1.High-Temperature Insulation & Shell Protection: The refractory castable has a low thermal conductivity (0.8–1.5 W/(m·K) at 1000℃) and excellent heat insulation performance. When poured as a lining (usually 150–300mm thick) in the incinerator chamber, combustion zone, and flue gas channels, it effectively blocks the high internal temperature (600–1300℃) from transferring to the metal shell, reducing the outer wall temperature to ≤120℃. This prevents the metal shell from deformation, oxidation, and damage due to overheating, extending the service life of the incinerator.
2.Resisting Corrosion & Scouring: Incineration of solid waste, hazardous waste, or garbage generates acidic/alkaline flue gas (HCl, SO₂, NOₓ) and high-speed dust particles, which severely erode and scour the lining. Our refractory castable is added with special anti-corrosion additives (such as magnesia, zirconia) and has a dense structure, effectively resisting chemical corrosion and physical scouring, avoiding lining peeling and leakage.
3.Adapting to Thermal Shocks: Incinerators often experience frequent temperature changes (e.g., startup, shutdown, load adjustment), leading to thermal shocks that easily cause ordinary refractory materials to crack. Our castable has excellent thermal shock resistance (complying with ISO 10081-1:2018), capable of withstanding 15+ cycles of 1100℃ to room temperature without cracking, ensuring stable performance during long-term cyclic operation.
4.Application Zones: It is widely used in key parts of incinerators, including the incinerator chamber (high-temperature combustion zone), secondary combustion chamber, flue gas duct, cyclone separator, and ash discharge channel—providing targeted protection according to the temperature and corrosion degree of each zone.
Key Product Advantages (Incinerator-Specific)
1.Exceptional High-Temperature Resistance: Formulated with high-quality raw materials (high-alumina, corundum, mullite), it can withstand long-term operation at 1000–1300℃, with a maximum service temperature of up to 1600℃ for high-grade corundum-based castable. It maintains stable structure and performance without softening, deformation, or melting under high-temperature incineration conditions, ensuring long-term reliability.
2.Strong Corrosion & Wear Resistance: Added with anti-corrosion and anti-wear additives, it effectively resists erosion from acidic/alkaline flue gas (HCl, SO₂, NOₓ) generated during waste incineration and scouring from high-speed dust particles. The dense structure (bulk density ≥2.6 g/cm³) prevents the penetration of corrosive media, reducing lining damage and extending service life.
3.Excellent Thermal Shock Resistance: Optimized material ratio and particle gradation ensure good thermal shock resistance, complying with ISO 10081-1:2018 and ASTM C133-17 standards. It can withstand frequent cold-heat alternations (temperature difference up to 300℃) during incinerator startup, shutdown, and load adjustment, avoiding cracking, peeling, and leakage.
4.Easy Construction & Good Integrity: It is a pourable, moldable material that can be poured on-site into any shape (adapting to the complex structure of incinerators) and formed into an integral lining without seams. This eliminates the weak points of brick-lined linings (such as gaps and joints), improving the overall insulation and corrosion resistance, and reducing construction time and labor costs.
5.Long Service Life & Cost-Effective: Under normal incinerator operating conditions, the service life of our refractory castable is 3–5 years (2–3 times longer than ordinary refractory bricks), reducing the frequency of lining replacement and maintenance. This lowers downtime and maintenance costs, improving the overall operational efficiency of the incinerator.
6.Customizable for Different Incinerator Types: We provide customized formulations according to the type of incinerator (solid waste, hazardous waste, medical waste) and the working temperature, corrosion degree, and wear condition of different zones. For example: high-alumina castable for general incinerator chambers, corundum-based castable for high-temperature combustion zones, and anti-corrosion castable for flue gas channels with strong acidity.
7.Environmental & Global Compliance: The raw materials are non-toxic, non-polluting, and comply with international environmental standards (ISO 14001:2015). The product fully meets ISO 10081-1:2018, ASTM C133-17, EU Waste Incineration Directive (2000/76/EC), and US EPA regulations, helping customers smoothly pass environmental inspections and meet CSRD compliance goals.
8.Good Bonding & Stability: It has excellent bonding performance with the incinerator metal shell (after surface treatment), forming a tight combination without detachment. The castable has high compressive strength (≥30 MPa at room temperature, ≥20 MPa at 1000℃) and flexural strength, ensuring stable structure even under high-temperature and high-pressure conditions.
