March 2005 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 440 Hz thermal oxidation unit. The ecoPHASER oxidizer produces very low No x. The level of super-stoichiometry allows for the minimum stack gas flow for given heat releases with minimum CO 2 recombination.
