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. 


  • 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.
  • 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.

Human Impact of the Habla Zig-Zag Kiln

  • Maintains the use of the existing workforce.
  • Working and living conditions of kiln workers is improved.
  • Living conditions for the immediate and wider population surrounding the kilns is significantly improved.
  • Cleaner firing technology and fuel optimization improves the health for all workers and their families.
