High Temperature Direct Fired Furnace Decomposition Pollution Control Energy Regeneration

Modern direct-fired furnaces integrate advanced IoT technology and achieve full automation through PLC or DCS systems. These systems monitor combustion status, temperature curves, and energy consumption data in real-time, allowing users to adjust parameters remotely to prevent overload or flameout risks. This intelligent management enhances safety, reduces manual intervention, and is ideal for precision manufacturing sectors requiring stable heat sources, such as semiconductor packaging and lithium battery drying. The integrated fault self-diagnosis function significantly reduces maintenance complexity and downtime.

This system is designed for a 150,000 ton/year CHP propylene oxide project, utilizing an integrated process of high-temperature oxidation with waste heat cascade utilization. It effectively treats highly complex, high-concentration petrochemical waste gas and wastewater containing propylene derivatives and reaction by-products. Through complete organic matter decomposition at 1200°C, the membrane wall boiler recovers heat to produce industrial-grade superheated steam, achieving both pollution control and energy regeneration objectives. The system supports China's first independent CHPPO technology, providing environmental protection for the propylene oxide industry chain extension, with annual steam reuse value exceeding 100 million yuan.

The Direct Thermal Oxidizer (DTO) initially heats the combustion chamber to the set temperature using fuel. Volatile Organic Compounds (VOCs) are then introduced and decompose into CO₂ and water at high temperatures, releasing significant heat. External equipment such as heat exchangers and boilers recover thermal energy from the purified high-temperature flue gas, achieving energy savings and reduced consumption.

Ruiding provides comprehensive system design based on factors including airflow, composition, concentration of VOCs to be treated, and desired removal efficiency. We deliver tailored, cost-effective VOCs treatment solutions. When waste gas concentration is sufficiently high, the system can operate without fuel input, maintaining furnace temperature through self-sustaining combustion at moderate Lower Explosive Limits (LELs).

• Incinerator withstands temperatures ≥1200°C with residence time ≥2 seconds, achieving ≥99.9% decomposition rate of VOCs and toxic byproducts. Waste gas/wastewater synergistic treatment solves multiphase flow, high salt content, and coking issues in petrochemical processes.
• Membrane wall boiler thermal efficiency ≥85% with annual steam output ≈340,000 tons (4.0MPaG/425°C). Directly drives production equipment with annual energy savings exceeding 80 million yuan. Multi-stage heat exchange reduces comprehensive energy consumption by 30% compared to traditional designs.
• Flue gas treatment combines bag dust removal with SCR denitrification, achieving particulate matter <10 mg/m³ and NOx <50 mg/m³, exceeding special emission limits. COD removal rate for wastewater after high-temperature oxidation ≥99.5% with no secondary pollution risk.
• Fully automated control with gas consumption <3.5 Nm³/ton steam, reducing operation and maintenance costs by 40%.
• Supports industrial application of China's first CHPPO technology, solving environmental protection challenges for propylene oxide processes. Core thermal oxidation equipment achieves 100% localization rate, breaking cross-technology monopolies.
