How the Habla Zig-Zag Kiln Works

The Habla Zig-Zag Kiln (HZZK) construction and operation is unique and differs from other zig-zag kilns in significant ways.

Significantly less masonry is heated during the firing process.
The zig-zag partitioned walls are themselves made of green bricks, which when fired also become the saleable product.
High fuel combustion efficiency means less fuel is consumed, almost entirely eliminating GHG, soot (black carbon) and CO₂
The directional zig-zag controlled air turbulence, creates higher temperatures, which increases fuel combustion efficiency and decreases fuel consumption.
Heat from fired bricks, is reclaimed from behind the fire zone and moved forward ahead of the fire zone accelerating the drying of green bricks and facilitating faster fire progress.
Increasing the speed of firing zone, means the kiln requires a smaller footprint.

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 the fuel source.
The firing process is accelerated by 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 with minimal emissions.
