Product Features
High Density Ceramic Fiber Board
- The product uses 1420°C grade high density ceramic fiber board with a bulk density of 0.45 g/cm3, providing excellent thermal insulation, heat preservation, and structural stability. This material effectively reduces heat loss and improves energy efficiency while maintaining strong mechanical integrity under high temperature conditions.
- The combination of low thermal conductivity and high strength ensures long term reliability for continuous SOFC startup operations. The fiber board structure also contributes to faster heating rates and reduced energy consumption during the preheating process.
Kanthal A-1 Resistance Wire with Fully Embedded Structure
- The heating module employs Kanthal A-1 resistance wire with an innovative fully embedded structure. This design minimizes the exposure of high temperature resistance wires, significantly reducing the risk of abnormal electrical discharge.
- The embedded configuration also protects the heating elements from mechanical damage and oxidation, extending the service life of the entire heating module. By enclosing the wires within the ceramic fiber matrix, the system achieves safer operation and more uniform heat distribution across the heating surface.
Three Point Temperature Control and Non Equidistant Wire Layout
- Each heating module features three point temperature detection and control at the upper, middle, and lower sections, enabling real time monitoring of temperature variations across different height zones. Combined with non equidistant resistance wire layout optimized according to local heat dissipation characteristics, the system matches heating power to regional heat loss patterns.
- This effectively suppresses temperature differences between top and bottom sections, creating a more uniform and stable heating environment for the SOFC stack.
Modular Design for Flexible Configuration
- The modular design allows customization according to different stack sizes, power requirements, and temperature specifications. Multiple modules can be combined with independent temperature zone control, providing flexible configuration options for various SOFC system architectures.
- From materials to structure, from heating to temperature control, every aspect is systematically designed to ensure stable, uniform, safe, and reliable high temperature heating capability for each module.
