CCS FEATURES

Improved Operability, Availability & Reliability

• All equipment off-the-shelf & familiar to the Operators
  - Safe, stable operation, same startup, shutdown and turndown as a PC fired burner
• Removes sulfur from furnace gases - near-zero SO₃:
  - Minimize water-wall wastage & corrosion,
• Improves Boiler Heat Rate (2 to 10%):
  - Allows lower furnace exit temperature
• - Use inert exhaust gas (low O₂) for pulverizer sweep air
  - Reject the coal moisture
  - Inert gas provides coal pulverizer safety
  - High combustion efficiency - (LOI < 1%)
  - Reduce particulate / ash load in furnace - less soot blowing
• No waste water disposal

CCS KEY STRATEGIC BENEFITS

• From Fundamental Combustion Theory to Field Demonstration
• Fires lower cost fuels - cut plant operating cost
• Meets EPA's new stringent CAiR initiatives for SO₂ & NO_x
• Allow power plant upgrade with waiver of NSR - PSD - NSPS
• Generates SO₂ & NO_x emission credits
• Low Retrofit Cost; to keep older, smaller power boilers competitive - improves capacity factor & dispatch
• Fits within Plant & Boiler Site Footprint
• Waste products have value (sell bottom ash & fly ash)
• No Hazardous or Toxic Chemicals Required

IT'S COAL GASIFICATION TECHNOLOGY!
