Environmental Benefits

Envirocoal is the best environmental solid fuel available. Gaseous emissions and particulate airborne emissions are lower than any other solid fuel. The amount of captured ash wastes are very small on an absolute basis and very low compared to other coals. The chemical composition of airborne and captured ash wastes renders them benign and suitable for recycling.

Sulphur Oxides
The occurrence of sulphur in Envirocoal is lower than nearly all coals in the world. Because of this, sulphur dioxide or SO2 emissions will be in the range 50 – 100 ppm or 0.20 – 0.26 lbSO2/mmBTU, lower than other coals, sometimes even with flue gas desulphurisation.

Nitrogen Oxides
The use of Envirocoal in most furnaces has resulted in lower nitrogen oxide or NOx emissions compared to other coals. In many cases, NOx emissions were reduced by as much as 40% when using Envirocoal as the sole feed. The exact amount of reduction will vary from unit to unit and also depends on the operating conditions.

Dust Emissions
In most dust collectors the particulate emissions of Envirocoal are approximately the same or less than other coals however some electrostatic precipitator tests have shown a marked reduction in emissions due to a combination of the very low inherent ash and the favourable fly ash resistivity.

• SO2 emissions decrease
• NOx emissions decrease
• Opacity decreases
• Wastes decrease
