The Habla Zig-Zag Kilns Concept

The Habla Zig-Zag Kiln Concept is simple. The kiln provides a unique, energy efficient, low emission technology with significant social, environmental and economic benefits.

Habla Zig-Zag Kiln Features Include

  • Long fire zone moving through stationary bricks.
  • Fan – The fire zone is advanced by a low horsepower induced draught, propelled by an axial flow fan.
  • Air flow – Increased air turbulence through use of fan and adjustable dampers, improving firing of bricks and fuel combustion.
  • Setting Pattern – The unique, long zig-zag fire zone allows even the most inferior of fuels to be burnt and clays to be fired – there is a low setting pattern.
  • Heat Recycling – Heat is recycled in a continuous process.
  • Pre-drying – Once the bricks have been fired, the heat is reclaimed and used to accelerate the pre-drying of ‘green’ bricks.
  • Structural – Green bricks are used as part of the kilns masonry structure, once the kiln is fired the green bricks become saleable (commercial) product
