Waste Heat Recovery RTO Equipment RTO Oxidiser For Metallurgy And Chemical Industry

Waste Heat Recovery Regenerative Thermal Oxidizer Energy Storage for Metallurgy and Chemical Industry

Designed for high-energy-consuming industrial applications, this system utilizes ceramic honeycomb heat storage technology and converts waste gas heat energy for reuse through an integrated waste heat recovery system. Achieving thermal efficiency exceeding 85%, it is ideal for high-temperature industries including metallurgy and glass manufacturing, significantly reducing fuel consumption and carbon emissions while balancing production efficiency with environmental protection.

This integrated incineration system supports a 100,000 TPY methyl methacrylate (MMA) production facility, processing:

• Concentrated process wastewater: 9,600 kg/h
• Biochemical wastewater: 3,000 kg/h
• Heavy component waste liquid: 1,264 kg/h with incineration temperatures of 950~1100℃

The complete system comprises a waste liquid incinerator, heat recovery unit, SNCR denitrification system, semi-dry scrubber, wastewater stripping column, induced draft fan and exhaust stack, with a total footprint of 60m x 30m.

The RTO consists of insulated chambers filled with high-temperature ceramic media. During operation, polluted air enters the oxidizer through an energy recovery chamber where ceramic media preheats it before introduction to the oxidation chamber. As air moves through the bed, temperature rises rapidly. The oxidation reaction occurs in the combustion chamber, converting pollutants into CO₂ and water vapor while releasing significant thermal energy.

Hot, clean gas exits through the second recovery bed, transferring heat to the ceramic media. In the next cycle, the process stream reverses direction, utilizing stored heat to preheat incoming air. Periodic switching of inlet, outlet, and purge processes completes the preheating, oxidation, heat storage, and release stages. This heat storage process enables thermal energy released during oxidation to be reused, substantially reducing fuel consumption for preheating.

To maintain optimal heat recovery efficiency, the process stream direction is regularly switched using automatic diverter valves controlled by the PLC system.
