Translation of Wall Thickness Requirements for Waste Tire Pyrolysis Equipment

The wall thickness of the core components (reactor/furnace liner) of waste tire pyrolysis equipment directly determines the service life and safety of the equipment. Here are the industry-accepted standards and recommendations:

1. Mainstream Wall Thickness Range

Standard thickness: 14–20 mm, with 16 mm being the most commonly used specification in the industry. When made of Q345R boiler steel, it can last 5–10 years under proper maintenance.

Heavy-duty durable type: 18–20 mm, suitable for high-load continuous production scenarios, which can extend the service life of the furnace liner by 6–10 months.

2. Relationship Between Wall Thickness and Durability

Material compatibility: Special boiler steels such as Q345R/Q245R must be selected, as they offer better high-temperature resistance and creep resistance. A thickness of 16 mm or more can effectively prevent issues like bulging and deformation of the furnace liner.

Safety redundancy: The equipment withstands high temperatures (approximately 400–550°C) and material pressure during pyrolysis. Excessively thin walls (less than 14 mm) are prone to cracking due to stress concentration, while walls thicker than 20 mm reduce heat transfer efficiency and increase energy consumption.

3. Other Factors Affecting Durability

Daily maintenance of the equipment (e.g., regular ash cleaning, anti-corrosion treatment).

Stability of production load (avoid frequent start-stop or overfeeding).

The completeness of the supporting flue gas purification system to reduce corrosion of the furnace wall by acidic gases.
