Thermal Liner: Temperature Range -50°C to 1200°C

Component Specifications

Definition

A thermal liner is a specialized component installed in the gas inlet section of industrial machinery to manage heat transfer, protect structural elements from thermal stress, and maintain optimal operating temperatures. It functions as an insulating barrier between high-temperature gases and the equipment's metal surfaces, preventing heat loss, reducing energy consumption, and extending component lifespan by minimizing thermal fatigue and corrosion.

Working Principle

The thermal liner operates on principles of thermal insulation and heat reflection. It creates a barrier that reduces conductive, convective, and radiative heat transfer between the gas stream and the equipment structure. By using materials with low thermal conductivity and reflective surfaces, it maintains temperature gradients, protects against thermal shock, and ensures stable process conditions in gas handling systems.

Materials

High-temperature ceramic fibers (alumina-silica), refractory metals (Inconel, Hastelloy), insulating blankets (fiberglass, mineral wool), ceramic matrix composites, with optional metallic coatings for corrosion resistance. Temperature range: -50°C to 1200°C, density: 100-400 kg/m³, thermal conductivity: 0.05-0.5 W/m·K.

Frequently Asked Questions

What is the primary function of a thermal liner in gas inlet sections?

The primary function is to provide thermal insulation, protect equipment from high-temperature gases, reduce heat loss, and prevent thermal stress on structural components.

How often should thermal liners be inspected or replaced?

Inspection should occur during regular maintenance cycles (typically every 6-12 months), with replacement needed when thermal degradation, physical damage, or reduced insulation performance is detected.
