Hazardous Waste Treatment Industrial Rotary Kiln Highly Flexible

Highly flexible rotary kiln system for comprehensive hazardous waste treatment with integrated dust removal and wet desulfurization capabilities.

Modern rotary kiln combustion systems offer exceptional flexibility, capable of utilizing various fuels including pulverized coal, natural gas, and heavy oil. Multi-channel burners can create different flame configurations (long flames, short flames) by adjusting primary air ratios. Certain kiln types can also process alternative fuels such as waste tires and plastics with replacement rates exceeding 30%. Advanced combustion control systems optimize air-fuel ratios in real-time by analyzing flue gas components (O₂, CO), ensuring maximum combustion efficiency while minimizing NOx generation.

Our rotary kiln system provides centralized, harmless disposal and energy recovery for multi-source mixed hazardous waste (solid/liquid/gas/domestic waste) within chemical plant areas. Through the integrated process chain of rotary kiln incineration, waste heat boiler steam co-generation, and multi-stage flue gas purification, we achieve the green production goal of "zero external transportation within the factory" for hazardous waste.

The rotary kiln features a long, inclined cylinder that rotates to uniformly heat waste materials in a high-temperature environment. During operation, high-temperature combustion effectively decomposes and processes organic materials and other waste components. The kiln's design ensures waste remains in the high-temperature zone for optimal duration, guaranteeing complete combustion while effectively neutralizing hazardous substances.

Ruiding's independently developed rotary kiln incorporates all traditional rotary kiln incinerator advantages while achieving significant advancements in heat exchange and ash burnout rates. The integration of high-temperature grate technology elevates the traditional second-stage combustion chamber to a more efficient second-stage furnace, further improving incineration efficiency.

Our system includes a chain-type evaporator that addresses inadequate air-waste contact issues in traditional rotary kilns. This optimization enhances waste heat exchange and combustion effectiveness, prevents slag formation inside the kiln, and significantly boosts both combustion efficiency and equipment lifespan. With high operational uptime, user-friendly maintenance, and suitability for medium to large-capacity processing needs, this rotary kiln solution offers customers an economically viable waste treatment option.

Ruiding provides customized hazardous waste solutions by analyzing critical parameters including elemental composition, calorific value, moisture content, viscosity, ash residue rate, and combustion rate. These tailored solutions are designed to meet each customer's specific waste characteristics and processing requirements.
