Component Specifications

Definition

A structural enclosure designed to contain and protect the heat exchange tubes, fins, and internal components of an economizer, providing thermal insulation, weather protection, and structural support while allowing proper airflow and access for maintenance.

Working Principle

The casing creates a sealed or semi-sealed environment that directs flue gas flow across heat exchange surfaces while protecting internal components from external contaminants, temperature extremes, and physical damage. It maintains pressure differentials and thermal efficiency through proper insulation and sealing.

Materials

Carbon steel (ASTM A36/A283), stainless steel (304/316L), aluminum alloys (6061-T6), with ceramic fiber or mineral wool insulation (ASTM C612/C795)

Technical Parameters

Thickness 3-12 mm
Pressure Rating 0.5-2.0 bar
Insulation Rating R-8 to R-15
Temperature Range -40°C to 650°C
Corrosion Resistance ASTM B117 salt spray >500 hours

Standards

ISO 13705, ASME BPVC Section VIII, DIN EN 13445, API 560
