Understanding Glass-Fused-to-Steel (GFS) Technology for Biogas Storage

GFS technology involves fusing a high-quality glass enamel coating onto both the interior and exterior surfaces of steel plates at high temperatures (820°C-930°C). This fusion bonds glass and steel at a molecular level, creating a robust, inert, and corrosion-resistant barrier combining:

• Steel’s strength and structural flexibility
• Glass’s impermeability and chemical resistance

Compared to painted or epoxy-lined steel tanks, GFS tanks offer superior durability in the highly corrosive environment typical of biogas storage, where gases such as hydrogen sulfide, methane, carbon dioxide, and moisture aggressively attack conventional materials.

Technical Specifications of Center Enamel GFS Biogas Storage Tanks

Design Features and Innovations

• Modular Bolted Construction: Enables rapid onsite assembly, scalability, and easier transport logistics compared to welded tanks.
• Gas-Tight Sealing: Special gaskets and bolt protection heads to prevent leaks and maintain biogas purity.
• Flexible Roof Options: Membrane or glass-fused steel domes tailored to operating pressures and storage volumes.
• Instrumentation Integration: Optional sensors for temperature, pressure, gas composition, and liquid level with remote data monitoring.
• Structural Reinforcements: Designed per AWWA D103-09 and ISO 28765 standards to withstand internal pressures and external environmental forces.

Advantages of Center Enamel GFS Biogas Storage Tanks

• Outstanding Corrosion Resistance: The glass coating protects against aggressive gases and chemical compounds, preventing rust and prolonging tank lifespan.
• Durability and Impact Resistance: Steel and glass fusion delivers structural strength able to resist environmental and operational stresses.
• Maintenance Friendly: Non-porous surface minimizes biofilm adherence, reducing cleaning frequency and costs.
• Leak Prevention: Bolted modular joints with quality sealing ensure airtight storage of biogas and liquid residues.
• Economic Efficiency: Faster installation reduces onsite labor costs; long life lowers replacement and repair expenses.
• Hygienic and Environmental Safety: The inert surface prevents contamination and supports environmental compliance.

Applications of GFS Biogas Storage Tanks

• Anaerobic Digestion Plants: For municipal, agricultural, and industrial organic waste biogas storage.
• Landfill Gas Storage: Capturing and storing biogas collected from landfill sites.
• Food Processing and Brewery Waste Biogas: Efficient gas collection and storage in organic waste valorization.
• Renewable Energy Facilities: Integration with CHP (combined heat and power) systems and gas upgrading plants.
• Agricultural Biogas Plants: Digesters fed by manure and crop residues producing energy onsite.
