How the Habla Zig-Zag Kiln Works

• 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.
