Fuel cleansing for efficient burn, longer equipment life

Nitrogen removal (partial) gives high oxidation burn (GGSSI)

Pulse-burn for most efficient high radiant heat to boiler firebox

Benson type once-through boiler

Microbial boiler tube corrosion inhibited

Used, refurbished & guaranteed turbines available to reduce costs

Bubble scrubber for emissions safeguard, no particulate, no bag-house

Point-to-point client power sale possible for 10 mW

Carbon Dioxide capture initiative available (GGSSI)

Source of fuel example

Source of Fuel (example)

800,000 tonnes; coal fines in settling pond,

4 kilometres from proposed generating station site,

at an altitude circa 40 metres lower than the site.

Advantages of example fuel source

Advantages of (example)Fuel Source

No road transportation; can be piped to site,

No washing or major pre-grinding required,

Tested and known component ingredients,

Friability index known,

High Calorific Value;

High Volatile Bituminous

11-12,000 BTU (6-6,500 kcal/kg);**

** = dry basis –main coal body

Fuel problems to overcome this example

Fuel Problems to Overcome(this example)

Some pockets high sulphur;

(By today's & future environmental standards)

40 metre pump head plus 1km piping.

Fuel treatment plan target synthetic clean orimulsion type cws

Fuel Treatment Plan:target = synthetic CLEAN “Orimulsion” type CWS

Crush coal to 200 mesh (74 microns) or 0.0029” in water

10 kW/hr per tonne

Micronize to 10-20 microns (fine slurry)

(Sonic cavitational deagglomeration)

(system energy use) = 5 kW/hr per tonne

Float off carbon & hydrocarbons

(Cascade Flocculation)

(system energy use) = 1 kW/hr per tonne

Precipitate contaminants & tramp fractions

Fuel Treatment Details: Micronizing: The Sonic Reactor Unit

Low frequency sonic technology

Low Frequency Sonic Technology

Sonication is the intense electromagnetic

vibration of a massive steel bar.

Reaction Chambers are at each end of

the bar, into which the material to be

processed is fed on a continuous basis.

For high volume industrial

applications such as rock grinding,

environmental remediation and

chemical processing.

The sonic system how it works

The Sonic System:how it works

Electro magnetic drive system

Electro-magneticDrive System

(3 magnet -75 kW, 104 Hz unit shown)

The 150 kW (60 Hz) unit uses 5 magnets with

non-sequential firing system.

Clean coal


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.

Coal media is torn apart exposing ash and contaminants for separation

Removal of contaminants prior to combustion drastically reduces air emission pollution potential!

Clean coal system operating costs

Clean Coal System operating costs

  • Power use; 500 kW

  • Flocculent; 60 cents per tonne, or

  • $0.003 or 0.3 cents per generated kW/hr.

  • Reject tramp fractions to cement works or dump.

Metso Cascade Flocculation System

Injection of fuel

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 ecoPHASERoxidizer produces very low Nox.

The level of super-stoichiometry allows for the minimum stack gas flow for given heat releases with minimum CO2 recombination.

Fuel cleanse advantages

Abrasions to boiler minimized

Longer boiler tube life

No energy losses through heating tramp components that do not contribute to energy

Less mass through thermal system for given energy = less volume in gas emissions

Major pollutants removed before firing

No heavy metals or sulphur*to volatilize and combine for emission compliance degradation.

Fuel cleanse advantages

Only combustibles to firing system

Cleaner burn

Full particulate gasification

Scrubbing costs minimized
