Why is HZZK Different from Other Zig Zag Kiln Technologies?

Each HZZK has the same authentic and proven design, components and operational features as conceived by the inventor of arch-less zig-zag kilns – Alois Habla. His original, zig-zag formula is proven and has excellent results.

It is the original Zig-Zag Kiln on which all subsequent zig-zag versions are based, however it is differentiated in a number of ways:

  • Efficient use of fuel reduces energy consumption.(using high, controlled temperatures).
  • The HZZK moves the fire through stationary bricks, using less energy. (The tunnel kiln, in contrast uses energy to move bricks through a stationary fire zone.)
  • Efficient firing process through use of long fire zone, rapid air flow and unique components.
  • Due to the excellent control of the fire and the low brick setting height, HZZK is ideally suited to fire perforated bricks and thin walled hollow large clay blocks; this conserves top soil, minimises land degradation and reduces energy requirements for the production of bricks and clay products.
  • Offers almost complete combustion (due to high, controlled temperatures).
  • Efficient use of generated heat which is recycled in a continuous process (using a unique heat recovery process).
  • Significant efficiencies in drying and cooling of bricks.
  • A small construction footprint – it can be quickly built with less masonry used.
  • A long fire zone (enables almost complete fuel combustion and fuel efficiency).
  • Roof – offers significant workforce and economic benefits.
  • No tall chimney (minimising fuel wastage).
  • Scalable operating modes either continuous or semi continuous.
  • Power source flexibility.
  • Easily mechanized.

The HZZK Difference: a Positive Impact on Workers

  • Improves health outcomes of all workers, and communities.
  • Promotes safe sustainable work practices and the dignity of all workers.
  • Uses and upgrades skills of existing workforce whilst maintaining employment.
  • Significantly reduces GHG emissions, CO2 and short lived climate pollutants (SLCP’s) particularly black carbon (soot).
  • Improves agricultural outcomes, locally and regionally.

The HZZK Difference: Improved Economics

  • Significant fuel savings, increase profits.
  • Production of consistent, quality, saleable bricks increases profits
  • Construction costs are lower.
  • Maintenance costs are lower.
  • Payback period is short.
  • Carbon credit generation is possible.
  • Significant foreign exchange savings are enabled as less imported coal is required Nepal and Bangladesh.
