Thermal Shield / Liner

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.

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.
