•  TUNNEL KILNS 


ELECTRIC, GAS OR LIQUID FUEL

Tunnel kilns are normally designed for continuous production and more homogeneous loads, capable of faster firing cycles than shuttle kilns. These kilns are also more efficient, with significantly lower energy consumption than shuttle kilns, considering the same production capacity.

The development of our solutions is ensured by a project technical team with extensive experience and expertise based on real applications, in the several areas. Insulation, heating, control and regulation systems are studied to have a rigorous distribution along the kiln in order to meet the requisites of the requested firing curves.

From the several applications of this type of kiln we highlight: heavy clay; porcelain, sanitaryware, earthenware, stoneware, decoration, using temperatures up to 1.450ºC.

In smaller kilns, with temperatures up to 1.150ºC, conveyor belt (with metallic mesh) with electromechanical drive can be considered.

HEATING PROCESS

Made through heating elements, gas burners (high speed – JET) or liquid fuel, projected according to each kiln characteristics and firing type.

INSULATION

Ceramic fibre and other low thermal mass materials, very flexible considering the cycle time: faster or slower cycles, according to the firing needs.

The insulation with refractory and insulating bricks, as well as refractory concrete, are normally applied on the manufactured models, balancing the requisites of each firing and the impact of the thermal shock on the kilns cars on continuous motion.

AUTOMATIC MOTION

We offer several solutions of kiln cars automatic motion systems, by hydraulic or electro mechanical process.
