  1. CLEAN COAL COMBUSTION ecoTECHClean Energy Sonic Standing Wave (pulse jet) combustion unit; laboratory demonstration Mission – Creating sustainable, ecologically sound, clean power generation facilities.

  2. Our Business CLEAN COAL & BIO-MASS TO ELECTRICITY

  3. How? • By cleaning the fuel BEFORE it is burned! • Proprietary Technologies combine for this. • By using new and proven combustion systems • Phase conversion reactor technology • By using heat recovery boiler systems • Highly advanced heat recovery steam generation • By using the world’s most efficient emission control equipment.

  4. Our History 42 Mbtu ecoPHASER sublimation reactor with vortex combustion (installed 1986) 20 years of R&D, now commercialized and available for projects. The Company has licensed several innovative technologies. The advanced systems create economies of operation and lead to enhanced profitability of ecoTECHprojects.

  5. Technology Targets Advanced Emissions Mitigation System: The World’s most efficient gas and particulate scrubber Advanced Coolant and Steam Recycling Circuit and System: Catonic filtration of system water . Looped water recovery circuit. Advanced Steam to Electricity Generation System: Co-generation utilizes latest design heat recovery steam generators Advanced Boiler Tube Structure and Maintenance: Biofilm (corrosion) blocking agents destroy microbial colony build-up Tubes embedded in radiant firewall fed by radiant firebox Advanced Power Station Structure and Architecture: Aesthetically and Ecologically superior design. Composite wall & roof structures with maximum heat, noise and seismic insulation. 3CR12 and 316 Stainless Steel Sub-structures. Advanced Control Systems: Ergonomic work stations and control room. All systems centrally and/or remote controlled by advanced software.

  6. Clean Coal Power A description of micronized clean coal (cws) fuel cleansing & SSW near zero Nox combustion

  7. Features Micronized Coal Fines Coal Fuel Decontamination Coal Water Mix (CWM) Atomizing 440 Hz Sonic Standing Wave Combustion Combined Cycle Power Generation Flue Gas Capture – CO2 Sequestration

  8. Example power project Information on an actual project under discussion follows to illustrate typical target results and methodology

  9. Summary of proposed power project No road transportation of fuel Slurry water recycled to fines pond, low cost, non-polluting flocculent 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)

  10. 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.

  11. 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

  12. Fuel Problems to Overcome(this example) Some pockets high sulphur; (By today's & future environmental standards) 40 metre pump head plus 1km piping.

  13. 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 (Cascade Flocculation)

  14. Fuel Treatment Details: Crushing Standard Crushers are used with slurried media.

  15. Fuel Treatment Details: Micronizing: The Sonic Reactor Unit

  16. 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.

  17. The Sonic System:how it works

  18. A Massive Oscillating Beam Beam Mounted Prior to Unit Assembly

  19. 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.

  20. 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. Coal media is torn apart exposing ash and contaminants for separation Force Curve Cavitation Bubbles

  21. Micronized Coal A 50 micron particle Cationic surface adsorbs methane or oil film

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

  23. 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

  24. 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.

  25. 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 * pyritic
