Our flat ceiling tunnel kiln incorporates comprehensive automation and thermal management systems for optimal clay brick production:

• Automatic coal powder feeding system
• Integrated smoke exhaust and ventilation
• Under-cart cooling and exhaust systems
• Gas combustion and waste-heat recovery
• Rapid cooling and back pressure balancing
• Three-door entry system with preparatory room
• Cold air isolation for consistent baking environment

Full-board foundation with plain concrete cushion and reinforced concrete beams/boards supporting kiln walls.

Pre-firing and cooling zones (below 200°C) use red bricks. Firing and insulation zones feature composite construction:

• Primary/secondary refractory clay brick inner layer
• Multi-layer insulation: aluminum silicate fiber, light clay bricks, aluminum foil, expanded perlite
• Red brick exterior walls

Concrete ceilings at kiln ends with composite suspended structure:

• Fire-retardant bricks and suspension system
• 304 heat-resistant hooks and I-beam supports
• Multi-layer insulation: refractory fiber, rock wool, aluminum foil, thermal insulation mortar
