What Differentiates Habla Zig-Zag Kilns from Other 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.
- 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.
- 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 i.e.in Nepal and Bangladesh.
