组件规格

定义
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.
工作原理
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.
材料
Carbon steel (ASTM A36/A283)stainless steel (304/316L)aluminum alloys (6061-T6)with ceramic fiber or mineral wool insulation (ASTM C612/C795)
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
标准
ISO 13705ASME BPVC Section VIIIDIN EN 13445API 560
