Hina Steel Belt Kiln For Continuous Production With High Thermal Efficiency And Reduced Firing Time
Overview
The tunnel kiln is a state-of-the-art firing system designed for continuous production, characterized by its long, straight structure with fixed walls and a roof. Equipped with tracks at the bottom for kiln cars, it features a high-temperature firing zone powered by centrally located combustion units. This innovative kiln utilizes counterflow principles to maximize thermal efficiency and fuel economy.
Key Features
- Continuous Production: Designed for high output and short cycles, delivering superior quality.
- High Thermal Efficiency: Utilizes counterflow principles to save 50-60% of fuel, benefiting from excellent heat retention and residual heat utilization.
- Reduced Firing Time: Drastically shortens firing duration to approximately 20 hours, compared to the 3-5 days required by traditional kilns.
- Labor-Saving: Simplified operation with external loading/unloading enhances working conditions and reduces labor intensity.
- Consistent Quality: Uniform temperatures in the preheating, firing, and cooling zones ensure high quality and minimal breakage.
- Durable Construction: Robust structure resists rapid temperature changes, extending the service life to 5-7 years before repairs are needed.
- Application Versatility: Suitable for firing blue bricks, tiles, ceramics, and new energy materials, with structures built or assembled from steel.
Operational Zones
- Preheating Zone: Incoming materials are preheated by the hot gases flowing towards the kiln entrance.
- Firing Zone: Centrally located combustion units create a high-temperature environment for effective firing.
- Cooling Zone: Cold air introduced at the kiln's end cools the finished products, with heated air reused for drying green bodies.
FAQ
1. What are the primary benefits of using a tunnel kiln?
Tunnel kilns offer continuous production with high output and quality, exceptional thermal efficiency, reduced firing times, labor-saving operations, consistent product quality, and durable construction.
2. How does the tunnel kiln achieve high thermal efficiency?
The tunnel kiln uses counterflow principles, where hot gases preheat the incoming materials and cold air cools the finished products, recycling heat and saving 50-60% of fuel.
3. What types of products can be fired in a tunnel kiln?
Tunnel kilns are versatile and can be used for firing blue bricks, tiles, ceramics, and new energy materials.
4. What is the typical firing time in a tunnel kiln compared to traditional kilns?
Firing in a tunnel kiln typically takes about 20 hours, significantly less than the 3-5 days required by traditional kilns.
5. How does a tunnel kiln improve working conditions?
Tunnel kilns feature easy operation and external loading/unloading, reducing labor intensity and improving overall working conditions.
