GFS Bio Gas Tank

Glass Fused Steel Tank- BIO GAS DIGESTOR

Glass-Fused Steel (GFS) tanks by Rostfrei Steels are perfectly suited for biogas plants. These tanks feature a premium glass enamel coating on both sides of the steel plates, combining the strength of steel with the corrosion resistance of glass. This ensures a long lifespan, minimal maintenance, and cost efficiency.

Biogas digesters are advanced systems engineered for the anaerobic digestion of organic waste, producing biogas and digestate. These systems are essential for sustainable waste management and renewable energy production, offering an eco-friendly solution to waste disposal challenges while contributing to energy independence. Biogas is a renewable energy source generated through the anaerobic digestion of organic matter in an oxygen-free environment. This process yields a gas primarily composed of methane (CH₄), carbon dioxide (CO₂), and hydrogen sulfide (H₂S). Biogas is produced in airtight tanks known as anaerobic digesters, which treat various organic materials, including agricultural waste, manure, municipal waste, plant matter, sewage, green waste, and food waste. The biogas produced can be utilized in a range of applications, such as:

  • Domestic cooking fuel
  • Liquefied transport fuel
  • Electricity generation for power grids
  • Production of bio-methane

Understanding a Biogas Plant

A biogas plant is an anaerobic digester designed to process biodegradable waste, such as farm waste, human waste, and crop residues. It operates in an environment devoid of light and oxygen, enabling anaerobic microorganisms to digest the biomass and produce biogas. This biogas, which consists of methane, carbon dioxide, and hydrogen sulfide, can be harnessed for various purposes, including electricity generation, gas-powered appliances, heating systems, steam boilers, and incinerators.

Key Processes of Digestion:

The digestion process in biogas plants typically involves two temperature-dependent methods:

  • Mesophilic Digestion
  • Optimal Temperature: 30°C to 38°C (or ambient temperatures between 20°C and 45°C)
  • Primary Microorganisms: Mesophiles
  • Thermophilic Digestion
  • Optimal Temperature: 49°C to 57°C (maximum 70°C)
  • Primary Microorganisms: Thermophiles

The Design Standards followed for Glass-Fused-to-Steel (GFS) tanks:

  • AWWA D103-09This standard is published by the American Water Works Association (AWWA) and provides guidelines for the design, construction, and inspection of bolted steel tanks for water storage.

PROCESS & TECHNOLOGY

A brief process of creating Glass-Fused-to-Steel (GFS) tanks involves several precise steps to ensure the quality and integrity of the finished product:

tank

Sheets & its Enamelling Process: after preparation of steel panels (by CNC punching holes, cleaning, shot blasting, curving) enamel coat is prepared. This coating process typically occurs in a special furnace where the panels are subjected to temperatures ranging from 700 to 900 degrees Celsius. At these high temperatures, the enamel fuses with the steel substrate, creating a durable and corrosion-resistant surface.

Fusion-Process

Quality Check: The quality check process for Glass-Fused-to-Steel (GFS) tanks involves thorough inspections and testing at various stages of manufacturing to ensure that the final product meets the required standards and specifications. Here's an overview of the typical quality check process – 1. Spark Test 2. DFT 3. Impact test

Heat-Furnace

Installation process:Once the panels are prepared, they are bolted together using hot-dipped galvanized high tensile nuts & bolts. These bolts are carefully selected for their strength and corrosion resistance, ensuring the longevity of the tank. An external N&B covers / caps are used to secure the bolted joints, providing additional protection against tampering and environmental factors.

Pre-Heating

Leakproof by - Sealing Joints using Sealant:To prevent any water leakage, all bolted joints are sealed using a sealant. This sealant helps create a watertight seal between the panels, ensuring the integrity of the tank structure.

Overall, these meticulous processes and components work together to create high-quality Glass-Fused-to-Steel tanks that are durable, reliable, and resistant to corrosion, making them suitable for various industrial, municipal, and agricultural applications.
