PARAMÈTRES DU PRODUIT
Description
30 Cubic Meter Gas-Fired Self-Controlled High-Temperature Tunnel Furnace
The 30-cubic-meter gas-fired self-controlled high-temperature tunnel kiln car furnace adopts high-speed natural gas burner heating technology, DCS distributed control system and all-fiber energy-saving furnace lining structure, and features high temperature uniformity, high degree of automation, low energy consumption and stable operation.
The furnace has an effective loading volume of 16.8 m³, a single furnace capacity of 35-50 tonnes, and a maximum design temperature of 1300℃. It employs a continuous circulation operation mode for the kiln car, combined with a high-speed swirl combustion system, to achieve uniform heat exchange around the material stack.
Caractéristiques du produit
- Large Capacity Design for Scaled Production
The kiln has a total volume of 37m³, with an effective loading volume of 16.8m³, and an estimated capacity of 35-50 tonnes. The kiln’s internal dimensions (L×W×H) are 14300×1740×1500mm. Specifically designed for high-temperature calcination of alumina powder, it boasts outstanding processing capacity and is suitable for large-scale industrial continuous production.
- High-Speed Burners Arranged in a Cross-Section for Uniform Temperature
The burners are arranged in two rows along the kiln’s side walls in a cross-section pattern, totaling 18 high-speed burners (230kW/burner). Eight kiln cars are housed within the kiln, with nine fire channels, each equipped with two burners. The burner nozzles are made of 310S material, offering excellent resistance to high-temperature oxidation. Each burner has an observation hole opposite it for easy monitoring of the combustion status. The airflow within the kiln swirls around the material stack, and the flue gas enters the exhaust port on the kiln car platform through the gaps around the stack and at the bottom, forming a swirling flame pattern, resulting in uniform kiln temperature.
- Comprehensive Safety Interlock Protection System
Each burner is equipped with a flame detection device. When the flame extinguishes, an audible and visual alarm is triggered, and the gas solenoid valve automatically cuts off the gas supply. The gas pipeline has an automatic overpressure safety venting system. In case of overpressure, the venting valve automatically opens to release gas, preventing damage to automatic control components and accidents. After on-site inspection and confirmation by the operator, automatic ignition can be achieved on-site or remotely.
- Multiple Firing Systems Stored, Flexible Recall
Multiple firing systems can be run (maximum 30 firing curves can be set), including a series of mechanical control actions, temperature control, and pressure control. A hierarchical control system composed of a touch screen, programmable logic controller (API), artificial intelligence instruments, sensors, and electric actuators enables functions such as firing process selection, real-time monitoring, data transmission, and real-time processing.
- Hinged Kiln Door + Tortuous Seal, Reliable Sealing
The kiln door adopts a hinged structure, with a compact overall structure, good sealing performance, and space-saving design. The kiln door and kiln body use a tortuous seal, providing a large sealing depth and excellent overall kiln sealing effect. The kiln car masonry and kiln body sealing also employ a zigzag sealing structure.
