CleanCoal
CleanCoal
Sonic micronization of crushed coal slurry is achieved via use of a proprietary high energy sonic oscillator-reactor, which tears the components of the coal apart due to its compression/cavitation de-agglomeration force cycle.

Injection of Fuel
The resulting fuel is a 70:30 coal/water emulsified slurry finer in particulate sizes than natural Orimulsion.
It is to be injected via a high pressure Olen-Johnson nozzle into an ecoPHASER (oscillating) standing sonic wave @ 440 Hz thermal oxidation unit.
The ecoPHASER oxidizer produces very low Nox.
The level of super-stoichiometry allows for the minimum stack gas flow for given heat releases with minimum CO2 recombination.
