定义
A thermal shield or liner is a specialized component installed within gas distributors or inlet nozzles to manage thermal conditions by providing insulation, heat reflection, or thermal barrier protection. It prevents excessive heat transfer to sensitive equipment, maintains process temperature stability, and protects structural components from thermal degradation in high-temperature industrial applications.
工作原理
Operates through thermal insulation principles using low-conductivity materials and/or reflective surfaces to reduce heat transfer via conduction, convection, and radiation. It creates a thermal barrier between high-temperature process gases and the equipment structure, maintaining temperature gradients and protecting downstream components.

High-temperature alloys (InconelHastelloy)ceramic composites (aluminazirconia)refractory metals (tungstenmolybdenum)or multilayer insulation systems with reflective foils and insulating spacers
Thickness
5-50 mm
Surface Finish
Ra < 3.2 μm
Pressure Rating
Up to 50 bar
Temperature Range
Up to 1600°C
Thermal Conductivity
< 1.5 W/m·K
标准
ISO 13784DIN 4102ASTM E84

常见问题

What is the primary function of a thermal shield/liner in gas distributors?

The primary function is to protect equipment from excessive heat, maintain process temperature stability, and prevent thermal damage to downstream components by creating an effective thermal barrier.

How do thermal shields differ from regular insulation?

Thermal shields are engineered components with specific geometries and material properties designed for direct integration into equipment, while regular insulation is typically applied as blanket or bulk material without structural integration.

What maintenance is required for thermal shields/liners?

Regular inspection for cracks, erosion, or deformation; cleaning to prevent buildup; and replacement when thermal performance degrades beyond acceptable limits.
