Technical Benefits

Storage
Envirocoal is a low sulphur, low ash sub-bituminous coal that is easily stored with no detrimental effect to the environment. The leaching of the coal by rainwater during storage will occur however the characteristics of trace metals, chemical species and radionuclides in the coal are amongst the lowest in the world.

Combustion
Envirocoal is a reactive coal and in most cases it is not necessary to grind the coal as fine as other coals to burn well. This can result in less energy being required to grind the coal. The high surface area, combined with higher volatile matter, results in excellent ignition, stable combustion and near complete char burnout. Combustion efficiency is often greater than 99.7%.

Ash
In envirocoal, the amount of silica and alumina can be less than 60% with pyrites being low or non existent and ash particles being relatively small in size. This will result in much less wear and erosion when using Envirocoal.

Ash Deposition
Ash deposition is always a potential problem in coal-fired furnaces. The deposition rate from Envirocoal is much lower and sometimes non-existent. The experience from using the coal is that slagging is generally very low. The use of wall blowers and soot blowers, which reduce thermal efficiency, can be reduced significantly. Fouling is non-existent.
