A tunnel furnace for solar panel pyrolysis provides continuous EVA removal, riscaldamento controllato, and stable material discharge. Yushunxin configures each furnace for single-glass, doppio vetro, or mixed PV modules. Standard systems process 500-1,000 kg/h. Larger projects require feedstock testing and customized thermal design. Multi-zone control, negative-pressure operation, trattamento del gas, and downstream separation protect glass quality and improve material recovery.
How Does the Tunnel Furnace Match Your Material and Output Plan?
01 · PlanThe furnace configuration should follow the project’s actual production plan. Module structure, hourly demand, obiettivi di prodotto, and operating hours affect every design decision. Perciò, Yushunxin reviews these conditions before confirming furnace dimensions, conveying speed, and supporting systems.
Configure the Heating Path Around Module Construction
The furnace can process single-glass, doppio vetro, mixed, rejected, rotto, and EVA- or POE-laminated modules. Single-glass modules contain one glass layer and an organic backsheet. Perciò, they usually require a shorter heating path and faster temperature adjustment. Double-glass modules contain two bonded glass layers and more thermal mass. Di conseguenza, they need slower heating and a longer holding section. Two-sided heat transfer also improves EVA decomposition between both glass layers. A typical industrial tunnel furnace uses a 28-40 m heating corridor. Tuttavia, module dimensions, spessore del vetro, polymer content, and breakage rate determine the final length.
Select the Feeding Route From the Product Sales Plan
The feeding route should protect the product that creates the highest project value. Whole-panel feeding suits projects targeting large and clean glass. Prima la linea rimuove scatole di derivazione e telai in alluminio. Poi, a flattening unit prepares each module for continuous furnace feeding. In condizioni adeguate, this route supports intact glass recovery above 92%. Recovered glass purity can also exceed 98%. Tuttavia, the result depends on module condition and process control. Pre-crushed feeding suits projects prioritizing silicon, rame, e frazioni contenenti argento. Dopo la rimozione del telaio, crushers reduce laminates to approximately 10-50 mm. This route improves heat exposure and supports downstream physical separation. Tuttavia, pre-crushing produces lower-value broken glass. Perciò, throughput alone should not determine the feeding design. The final solution must follow the planned sales route for glass and silver-rich materials.
Scale Capacity to the Real Operating Window
Standard tunnel furnace systems process 500-1,000 kg/h with continuous feeding and discharge. Larger projects can reach 2,000 kg/h after representative feedstock testing. Daily output depends on effective operating hours rather than nominal shifts. Inoltre, panel weight, feeding density, belt speed, and residence time affect actual production. Higher throughput increases heat demand, vapor volume, cooling load, and exhaust-treatment capacity. Perciò, Yushunxin recalculates furnace width, drive load, flusso di gas, and purification capacity before quotation. Continuous feeding must remain uniform to prevent blockages and incomplete pyrolysis.
How Can a Zoned Tunnel Furnace Solution Protect Glass During EVA Removal?
02 · SoluzioneA tunnel furnace must remove EVA without damaging recoverable glass. Perciò, Yushunxin uses staged heating, adjustable conveying, and controlled heat circulation. This thermal solution limits sudden temperature changes. It also supports stable separation of glass, celle di silicio, e nastri metallici.
Create Controlled Heat
Gradient Across Three Sections
Controlled Heat Gradient divides the furnace into Three Process Sections. Preheating removes umidità, the main zone decomposes EVA, and cooling completes carbonization.
Match Belt Speed
With Module Structure
Belt Speed controls heat exposure and residence time. Different Module Structure requires different settings to achieve stable EVA removal and protect glass quality.
Configure Dual-Side Heating
For Double-Glass Modules
Dual-Side Heating improves temperature uniformity for Double-Glass Modules. Multiple zones and thermocouples reduce thermal stress and improve EVA separation.
Optimize Furnace Design
For Stable Production
Furnace length, heating power and gas extraction should match module type and capacity. Integrated control protects glass quality and supports continuous operation.
How Can Intelligent Control Stabilize Continuous Solar Panel Pyrolysis?
03 · Intelligent Control
Continuous production depends on coordinated control, non solo la temperatura del forno. Yushunxin links heat, pressione, ossigeno, trasporto, and gas extraction through one PLC system. Perciò, operators can correct deviations before they affect EVA removal, glass quality, or hourly output. This structure also provides clear evidence during commissioning and final acceptance.
Closed-Loop Control Keeps Heat Stable
Closed-Loop Control uses PLC, thermocouples and fans to manage temperature, negative pressure and belt speed. It keeps EVA decomposition stable under different module conditions.
Oxygen Interlocks Protect Low-Oxygen Process
Oxygen Interlocks monitor oxygen levels and trigger nitrogen protection, heating stop and emergency actions. This prevents unstable conditions from affecting production safety.
Acceptance Data Confirms Rated Production
Acceptance Data verifies temperature, pressione, ossigeno, velocità, throughput and residual EVA during commissioning. Representative tests confirm real capacity and product quality.
How Can a Closed-Loop Furnace System Recover Heat and Separate Saleable Materials?
04 · MaterialsThe tunnel furnace should connect heat recovery, gas cleaning, raffreddamento, and separation within one controlled route. This structure reduces energy waste and protects downstream product quality. It also gives project owners cleaner material handling and clearer operating data.
Reuse Pyrolysis Gas to Support Continuous Heating
Match the Gas Treatment System to Feedstock Conditions
Build the Discharge Route Around Product Value
