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

1. Preheating Zone: Incoming materials are preheated by the hot gases flowing towards the kiln entrance.
2. Firing Zone: Centrally located combustion units create a high-temperature environment for effective firing.
3. Cooling Zone: Cold air introduced at the kiln's end cools the finished products, with heated air reused for drying green bodies.

FAQ
