Membrane bar

Water wall panel is an important heating surface of boiler. It has been introduced as leading boiler fabrication technology from advanced countries. In recent decades, the fabrication of super-critical and ultra super-critical boiler with 600MW and 1000MW capacity adopt membrane panel for waterwall without exception.

 

Membrane bar is integral component that connects waterwall tubes together. It plays crucial role for waterwall tube spacing and ovality.

 

Membrane bar benefits for optimization of boiler

 

• Enhance structural integrity. Membrane bar provides support and reinforcement of waterwall tubes to reduce risk of deformation. Overall strength and integrity of waterwall is increased.
• Improve boiler efficiency. Membrane bar increases heating surface of waterwall to maximize heat absorption, and decreases tube failure under high pressure.
• Gas tight to avoid flue gas leakage.
