High Efficiency 380V Cross Fired Glass Melting Furnace | Custom 200TPD Capacity

The 380V cross fired glass melting furnace is a high-efficiency, industrial-grade thermal processing system tailored for medium-to-large scale glass manufacturing. Different from traditional end-fired furnaces, this model adopts an opposed sidewall burner layout, with flames horizontally traversing the melting tank perpendicular to the glass material flow direction. The unique cross firing structure forms an all-round sweeping heat flow on the batch material surface, greatly improving radiative and convective heat transfer efficiency, realizing uniform glass melting and stable production output.

Equipped with a mature regenerative heat recovery system, this cross fired glass furnace effectively recycles waste flue gas heat, reducing unit energy consumption while controlling CO₂ and NOx emissions perfectly. It complies with global industrial decarbonization and low-cost production trends. The furnace features an expanded melting zone and optimized structural design, supporting flexible capacity customization ranging from 50TPD to 750TPD, with the classic 200TPD as our mainstream specification. The 200TPD model is equipped with operating power of 500~550 kW and requires total investment of USD4~5million. It is widely applicable for daily-use glass, industrial glass and other mass production scenarios. Capable of 24/7 uninterrupted stable operation, it balances high production efficiency, low energy consumption and environmental protection performance.

• Precise & Uniform Temperature Field Control

  The opposed cross-flame design avoids local overheating inside the melting tank, effectively reducing refractory material loss and glass product defects. It optimizes glass melt uniformity and improves the finished product qualification rate significantly.

• Independent Zonal Heating & Flexible Adaptability

  Each group of burners along the furnace body is independently controlled, realizing accurate longitudinal temperature gradient adjustment. It can adapt to various glass formulas and different production pull rates, meeting diversified production customization demands.

• Wide-Range Customizable Production Capacity

  Supporting scalable throughput design with flexible capacity options from small 50TPD to large 750TPD, covering small-batch customized production and large-scale industrial mass production. The 200TPD standard model is mature and stable, with excellent cost-performance for mainstream market demands.

• High-Efficiency Regenerative Heat Recovery System

  Adopts dual regenerator cyclic heat storage technology, which can preheat combustion air to high temperature by recycling waste flue gas heat. It greatly reduces fuel consumption per ton of glass, lowers overall production energy cost and achieves outstanding energy-saving effects.

• Stable Dual-Deck Reversing Mechanism

  The upgraded double-deck reversing unit realizes smooth and reliable switching of flow directions of flame and flue gas. It ensures long-term stable combustion conditions, reduces equipment failure rate and extends the overall service life of the furnace.

• Low Emission & Eco-Friendly Operation

  Optimized combustion structure and waste heat treatment configuration effectively reduce carbon and nitrogen oxide emissions, meeting international environmental protection standards and helping enterprises achieve green production upgrading.

The cross fired glass melting furnace adopts a modular integrated structural design, with multiple independent and interlocking functional zones to ensure systematic and efficient melting operation:

• Melting Tank: The core functional area integrating batch melting, clarification and refining processes, built with high-grade fused-cast AZS refractory materials, resistant to high temperature and strong glass corrosion, ensuring long-term stable operation.
• Breast Wall: Stably supports the furnace crown, forms a closed flame combustion space on both sides of the melting tank, and optimizes internal heat circulation.
• Furnace Crown: Adopts high-quality silica-based arched roof structure, which efficiently reflects radiant heat to the glass melt surface and improves heat utilization rate.
• Flue Ports: Symmetrically arranged on both sidewalls, serving as the passage for fuel-air mixture intake and high-temperature flue gas exhaust, matching the cross-flame combustion mode.
• Regenerators: Dual-chamber heat storage equipment filled with high-performance checker bricks, cyclically stores and releases waste heat to preheat incoming combustion air, realizing energy recycling.
• Cooling Section: The downstream temperature buffer zone, which gradually reduces the temperature of molten glass to meet the subsequent forming and conditioning process requirements.
• Flue Channel: Centralizes and collects exhaust flue gas from each port, stably guides flue gas to the reversing unit and waste heat treatment system.
• Double-Deck Reversing Unit: Automatic control core of the furnace, realizing cyclic switching of combustion and exhaust processes to support continuous and uninterrupted production.
• Optional Waste Heat Treatment System: Expandable downstream equipment for secondary waste heat recovery and flue gas purification, further improving energy efficiency and meeting higher environmental protection standards.

• Melting Tank

  As the core melting and clarification integrated structure, it is lined with high-temperature and corrosion-resistant refractory materials. It can withstand long-term high-temperature glass liquid scouring, ensuring sufficient melting time and uniform clarification effect, avoiding glass impurities and bubbles.

• Regenerator

  The core energy-saving component of the furnace. It absorbs heat from high-temperature flue gas during exhaust phase and transfers heat to incoming cold air during combustion phase. The high-temperature preheated air significantly reduces fuel combustion consumption and improves overall thermal efficiency.

• Port Assembly

  Key equipment for fuel and air mixing and circulation. It realizes the full mixing of natural gas, LPG or fuel oil and preheated hot air to form stable cross flame. It completes air intake combustion and flue gas exhaust switching in one unit, ensuring efficient and sufficient combustion.
