How it works

Efficient Use of Fuel reduces energy consumption

  • Significantly less masonry is heated during firing process.
  • The zig-zag partitioned walls are themselves made of green bricks, which when fired, become saleable product.
  • Higher fuel combustion means less fuel is consumed, almost entirely eliminating soot (black carbon) and COemissions.
  • The directional zig-zag controlled air turbulence, creates higher temperatures, which increases fuel combustion and decreases fuel consumption.
  • Heat from fired bricks, is reclaimed from behind the fire zone and propelled forward ahead of the fire, accelerating the drying of green bricks and facilitating faster fire progress.
  • Increasing the speed of firing zone, means the kiln requires a smaller footprint, although the footprint is smaller the kiln provides similar production outputs to that of comparable target replacement kilns i.e. the FCBTK or MCBTK.

Efficiency of the Firing Process

  • The HZZK offers almost complete fuel combustion.
  • The fire moves through stationary bricks in a zig-zag fashion creating critical air turbulence allowing for;
    - Even heat distribution
    - Maximum heat generation
    - Maximum energy extraction from fuel source
  • The firing process is accelerated through creating air flow and turbulence (draught) through the use of a low horsepower axial fan.
  • Control valves and dampers, are used in conjunction with the fan, resulting in increased directional air turbulence and highly efficient fuel combustion (minimal emissions).

Efficient use of generated heat

  • Heat is moved ahead of the fire to pre-dry green bricks before full-firing, this allows for more rapid fire progression and increased brick production output.
  • Pre-drying is achieved by extraction of heat from fired bricks behind the fire zone, with clean, dry heat.
