Features:
- Utilizes imported high-temperature furnace wires with an integrated electromechanical design. The reactor loading/unloading mechanism is driven by bottom-mounted mechanical transmission, ensuring simple and convenient installation and operation.
- The control system adopts Siemens PLC design, with gas flow measured and controlled by mass flow controllers (MFCs), ensuring accurate and reliable flow rates with real-time display. Features self-learning temperature control algorithms, programmable settings, and control modes including open-loop stepwise and closed-loop fully automatic.
- Temperature transmitters employ solid-state two-wire modules with automatic temperature compensation and linearization.
- Capable of simulating the entire testing process to verify system operational status.
- Automatically activates the ventilation system during testing to expel indoor CO gas, preventing operator poisoning and ensuring air circulation.
- Connects to a touchscreen computer for real-time display of temperature and gas flow curves. Includes a CO2 flow deficiency alarm function.
- Equipped with over-temperature alarm and automatic power cutoff to prevent damage from thyristor failure, thermocouple damage, or signal interference.
- Includes over-pressure protection.
- Thermocouples are protected by GH3030 high-temperature alloy steel sleeves.
Technical Parameters:
A. Standard Control Process:
- Room temperature to 1100°C, heating rate: 15°C/min (adjustable).
- At 400°C, introduces 0.8L/min N2 for protection.
- At 1050°C, preheats CO2.
- At 1100±5°C, stabilizes for 10min, switches off N2, and introduces 5L CO2 for a 2h reaction.
- Furnace stops heating; reactor descends and exits the furnace. CO2 is cut off, and 2L N2 is introduced for protection.
- An alarm sounds when the coke cools to 100°C, marking the end of the test.
- The entire process is automatically controlled by a Siemens PLC.
