Description
SOFC Fuel Cell Start-Up Preheating Furnace and Heating Module
The SOFC fuel cell start-up preheating furnace and heating module is a high-safety, high-temperature-uniformity, and high-reliability heating system specifically designed for the start-up preheating of solid oxide fuel cells (SOFCs). Addressing the stringent requirements for temperature rise stability, temperature uniformity, high-temperature insulation, and operational safety during SOFC start-up, our company has independently designed and developed this series of preheating furnaces and modular heating components, providing a stable and reliable heat source solution for fuel cell stack start-up, preheating, and high-temperature operation.
The product uses a 1420℃ high-density ceramic fiber board (volume density 0.45g/cm³) paired with Kanthal A-1 resistance wire, employing an innovative fully embedded heating structure. This design reduces the exposure of the high-temperature resistance wire, lowers the risk of abnormal discharge, effectively protects the heating element, and improves the safety and lifespan of the heating module.
Product Advantages
- 800℃ High-Temperature Design
This heating solution can meet the requirements of SOFC fuel cell preheating and high-temperature operation, and also leaves enough temperature margin to withstand long-term use. The system is stable and reliable under complex operating conditions.
- 0.45g/cm³ High-Density Ceramic Fiber Board
Finding a balance between low thermal conductivity, insulation performance, and structural strength can reduce heat loss, improve energy efficiency, and ensure the structural stability of the module at high temperatures.
- Kanthal A-1 Resistance Wire
Utilizes internationally mature high-temperature resistance heating material (Kanthal A-1), possessing excellent high-temperature stability and oxidation resistance, high heating efficiency, and long service life.
- Fully Embedded Heating Structure
Reducing the amount of exposed resistance wire at high temperatures lowers the risk of abnormal discharge, enhances the protection of heating elements, and improves system safety.
- Precise Temperature Control at Top, Middle, and Bottom Points
Real-time monitoring of the temperature status of different areas of the module provides a precise control basis for temperature uniformity, ensuring uniform heating of the fuel cell stack.
- Non-equidistant resistance wire layout
Thermal power optimization has been implemented to address the different heat dissipation conditions in the upper and lower regions, effectively improving the temperature difference between the upper and lower parts caused by traditional uniform winding, resulting in higher temperature field uniformity.
- Modular design
It can be customized according to different fuel cell stack sizes, power and temperature requirements, supports multi-module combinations and independent temperature zone control, and flexibly adapts to the needs of various SOFC systems.
