SIGNIFICANTLY IMPROVED ENERGY EFFICIENCY

Habla Zig Zag Kiln: Proven ResultsThe 2016 HZZK project results provide a catalyst for change to the highly contaminating brick industry of the developing world.

The HZZK provides a clean brick firing solution to the environmental and production challenges of the brick industry using authentic zig-zag technology as designed by the inventor of arch less zig-zag technology – Alois Habla.

The HZZK successfully replaced the high-polluting, energy intensive South African clamp kiln in 2016.

Independent Energy Balance and Emissions reports show excellent results:

HZZK Specific Energy Consumption ComparisonSPECIFIC ENERGY CONSUMPTION (SEC):
>80% Saving @ 0.74Mj/kg

HZZK = 0.74 MJ/kg fired brick indicated an 81.5% improvement when compared to the SEC of the South African Clamp = 3.99 MJ/kg fired brick.

 

SIGNIFICANT CO2 EMISSION REDUCTION:
> 60% Saving @ <70g/kg

Emission results were independently monitored and the results indicate world leading outcomes.

Due to the unique design features and almost complete fuel combustion from the swift, zigzag air-flow, high temperatures and  long fire zone, the environmentally sustainable HZZK project demonstrated:

  • Significant reduction in greenhouse gases (GHG);
  • The lowest CO2 emissions (lower when compared to all other kiln designs including the SA Clamp kiln and all Indian kilns);
  • Negligible particulate emissions particularly of black carbon and short lived climate pollutants (SLCP’s).

 

HZZK Coal Consumption ComparisonSIGNIFICANT FUEL SAVINGS:
>80% Saving @ 108kg coal per 1,000 bricks

Results reflected a dramatic reduction in coal use and an 82% reduction in fuel consumption compared to the SA Clamp kiln.

Coal used per 1,000 bricks by HZZK at 108kg compared to the South African Clamp Kiln at 583kg per 1,000 bricks.

 

Suspended Particulate Matter (SPM):
> 80% SAVING @ 30mg/nM3G

Results were measured at 30mg/nM3, well below the legislated South African emissions limit (50mg/nM3).

This also equates to a >90% improvement over current Indian average figures of 750mg/nM3.*

 

Sulphur Dioxide (SO2):
> 80% Saving @ 50 mg/nM3

Results were measured at 50 mg/nM3 which represents a potential 80% reduction when compared to the South African limit of 400 mg/nM3. This co-pollutant is known to cause asthma respiratory disease and to contribute to ‘acid rain’, in turn impacting agricultural production.

 

Black Carbon (BC):

Monitoring showed negligible deposition of particulate matter (PM) from the HZZK.

 

HZZK Key Operational Results 2016-17 Compared to Other Kilns

Roll-out of HZZK clean technology will remove the now prevalent black carbon emissions (smoke plumes) of current kilns in developing countries and improve air quality and pollution.

The HZZK offers major change to the brick industry of the developing world with consistent, high quality brick production, energy-efficiency (fuel savings, from any source), and pollution reduction enabling workplace, agricultural and health improvements for local and regional communities.
