Technical Advantages of NJHD Stress-Free Helical Coil Structure Ascension Pipe

1. Safety Assurance: Even if the pressure-bearing component leaks, the medium will not enter the carbonization chamber, ensuring coke oven safety.

2. Medium-Pressure Steam Generation: Achieves steam pressure ≥4.0 MPa.

3. High Steam Yield: Produces over 120 kg of steam per ton of coke.

4. Enhanced Heat Transfer: Straight fins added to the raw gas channel improve heat transfer, raise wall temperature, and prevent tar condensation.

5. Dual Heat Carrier Options: Supports both water and thermal oil circulation for waste heat recovery.

6. Stress-Free Helical Coil: Eliminates thermal fatigue, extending equipment lifespan.

7. Anti-Coking Technology: Thermal barrier agents increase wall temperature, preventing coking; graphite cycle extended to one month (with maintenance).

8. High Efficiency: Fully replaces tube heating furnaces with 95%+ energy utilization.

9. Superheating Capability: Steam heated to over 400°C.

System Features

1. Load Adaptability: Adjusts wall temperature to avoid condensation (30%~120% load range for ovens; 30%~250% for individual pipes).

2. User-Friendly Control: Simple operation, high reliability, and low labor intensity.

3. Economic & Environmental Benefits: Integrates with chemical processes, replaces tube furnaces, and reduces emissions.

4. Flexible Steam Output: Same system supplies both saturated and superheated steam.

Safety

1. Double-Layer Protection: Leakage detection prevents water ingress into the coke oven.

2. Emission Control: Maintains wall temperature to eliminate black smoke during lid opening.

3. Robust Material: Corrosion/wear-resistant inner tube withstands dry firing and system failures.

4. Stress-Free Durability: Handles extreme and variable operating conditions.

5. Low Failure Rate: Simplified operation minimizes errors and downtime.
