Product Introduction
The Zexuan Waste Heat Recovery Equipment is a high-integrity, thermal optimization solution engineered to capture and repurpose high-temperature waste heat from industrial exhaust, flue gases, and process effluents. Designed seamlessly for waste incinerators, RTO/TO thermal oxidizers, metallurgical furnaces, and heavy industrial boilers, this system transforms wasted thermal energy into valuable plant utilities such as steam, hot water, hot air, or thermal oil. By combining cutting-edge thermodynamics with robust, anti-corrosive heat exchanger engineering, Zexuan empowers global enterprises to drastically cut supplementary fuel consumption, lower operational costs, and reduce their overall carbon footprint while ensuring full structural reliability.

Key Technical Advantages:

  • Maximum Thermal Optimization: Achieves heat recovery efficiency up to 70%–90%, directly reducing plant auxiliary fuel demands and lowering greenhouse gas emissions.

  • Anti-Corrosive & High-Temperature Metallurgy: Fabricated using premium stainless steel (SS316L/SS310S), Inconel, or specialized anti-fouling coatings to withstand high-sulfur flue gases, acidic vapors, and extreme thermal cycling.

  • Customized Engineering Layouts: Available in diverse structural configurations including shell-and-tube, finned-tube, heat pipe, and recuperative heat exchangers, tailored precisely to your plant's pressure drop and space constraints.

  • Low Maintenance & Smart Control: Equipped with automated soot-blowing systems and dynamic temperature bypasses to prevent ash clogging, dew-point corrosion, and thermal overloads, managed entirely via an integrated PLC control cabinet.

Technical Specifications：

  • Flue Gas Inlet Temperature: Up to 1,000℃.

  • Heat Recovery Media Options: Steam, Hot Water, Heated Process Air, Thermal Oil.

  • Heat Exchanger Type: Shell & Tube, Finned Tube, Heat Pipe, Plate Matrix.

  • Control System: Smart PLC Cabinet with automated safety bypass loops and feedforward thermal monitoring.

Target Applications：

  • Environmental Containment: Secondary heat recovery loops for RTO, RCO, and TO thermal oxidizers.

  • Petrochemical & Refining: Cracking furnaces, process vent heaters, and refinery boiler flue gas recovery.

  • Metallurgy & Kilns: Blast furnace exhausts, cement rotary kilns, and glass manufacturing waste streams.

  • Power Generation & Utilities: Industrial boiler blowdown recovery and economizer retrofits.
