Why is HZZK Different from Other Zig Zag Kiln Technologies?
The Habla Zig-Zag Kiln has a standardised core design and operational features which are completely unique and different to all other kilns (including all other zig-zag designs) that operate in developing nations today.
The authentic HZZK as conceived and constructed by the inventor of arch-less zig-zag kilns, Alois Habla, implements his proven and versatile zig-zag formula. The technology has demonstrated unsurpassed energy efficiency and emission results.
- Efficient use of fuel reducing energy consumption, using high, controlled temperatures.
- The movement of the fire through stationary bricks, using less energy. As opposed to, the tunnel kiln, which uses energy to move bricks through a stationary fire zone.
- Efficient firing process through the use of a long fire zone, rapid airflow and unique components.
- 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 topsoil, minimises land degradation and reduces energy requirements for the production of bricks and clay products.
- 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.
- Small construction footprint that can be quickly built with less masonry.
- Long fire zone enabling almost complete fuel combustion and fuel efficiency.
- Roof – offering significant workforce and economic benefits.
- No tall chimney – minimising fuel wastage and workplace pollution.
- Scalable operating modes either continuous or semi-continuous.
- Power source flexibility.
- Easily mechanized technology.
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.
A Key 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.
- The payback period is short.
- Carbon credit generation is possible.
- Reduces annual foreign exchange expenditure on imported coal for brick firing. Nepal spends a reported US$153.7 million p.a on coal.
