Shuttle Kiln Introduction:
A shuttle kiln is a car-bottom intermittent kiln, in which one or multiple kiln cars can be loaded. Because the kiln cars move in and out like a drawer, it is also called a “drawer kiln.” Widely used in ceramics, building materials, and related industries, the shuttle kiln is well known for its excellent sealing performance, uniform temperature distribution, and remarkable energy-saving effect.
Our product pricing is customized according to your production capacity requirements and detailed project drawings, ensuring the most cost-effective solution for your brick plant.
1. Foundation & Structure (parameters may vary by project)
(1) Foundation:
400 mm reinforced concrete (100 mm C15 base + 300 mm C20 reinforced concrete), with 3:7 lime-soil compacted subgrade; ground bearing capacity ≥ 8 t/m².
(2) Kiln Body:
Welded steel structure with high strength and anti-vibration performance, equipped with platforms, ladders, railings, and inspection ports for convenient operation and maintenance.
(3) Kiln Walls:
Multi-layer composite structure (cordierite-mullite brick + lightweight high-alumina brick + ceramic fiber + steel plate), thickness approx. 500–520 mm, providing excellent insulation and thermal efficiency.
(4) Kiln Roof:
Arch roof design, composed of JM26 cordierite-mullite brick, lightweight high-alumina brick, and ceramic fiber blanket, with a total thickness of about 565 mm.
2. Kiln Door & Kiln Car
Kiln Door:
Steel shell with rail-guided movement. Refractory lining same as kiln wall, multi-layer insulation, total thickness about 500 mm; equipped with motor, reducer, and gear drive.
Kiln Car:
Frame welded with channel steel and I-beams, fitted with cast steel wheels, 45# steel axles, and high-temperature bearings. High mechanical strength. Car size approx. 3.0 m (L) × 3.15 m (W). Equipped with 4 kiln cars (2 inside, 2 outside).
3. Sealing System
Excellent sealing ensures temperature uniformity and energy efficiency:
· Kiln door to kiln body/car: fiber blanket filling + labyrinth sealing;
· Kiln car to kiln body sides: mechanical soft seal;
· Kiln car to rear kiln wall: refractory fiber filling with compression sealing.
4. Combustion System
Burners:
20 high-speed burners, staggered arrangement along the lower sidewalls, jetting upward. Small-flow multi-point layout ensures fast heating, even temperature, and complete combustion.
Control Mode:
Gas flow manually regulated by flow meters; high-speed burners stir the atmosphere, improving kiln temperature uniformity.
Pipeline System:
· Air system: Stainless steel pipelines, centralized air supply, 2 × 11 kW fans (one standby), each with frequency converter.
· Gas system: Seamless steel pipelines, equipped with shut-off valves, filters, solenoid safety valves, and relief valves.
5. Exhaust System
Rear-side bottom exhaust design: hot gases flow upward through convection heating, then pass through flues beneath the kiln car to the exhaust port, finally extracted by induced draft fans.
Equipped with 2 × 15 kW exhaust fans (one standby), with cold-air damper and temperature monitoring for safe operation.
6. Control & Operating Features
· 20 burners divided into 5 temperature zones, with automatic regulation for uniform heating.
· Products loaded/unloaded outside the kiln, reducing labor intensity and heat loss.
· Lower energy consumption compared with traditional downdraft kilns.
· Flexible for different firing processes.
7. Key Advantages
· Excellent temperature uniformity, ideal for high-quality firing.
· Superior sealing prevents air leakage, improving energy efficiency.
· Strong and durable structure with easy maintenance and long service life.
· High-speed burners and optimized layout ensure complete combustion and rapid heating.
