CASCADED HUMIDIFIED ADVANCED TURBINE

CHAT FOR DISTRIBUTED POWER GENERATION

Distributed Power Generation CHAT Cycle, US Patents 5,347,806 and 5,386,688 by Dr. Nakhamkin

Distributed-Power-Generation CHAT Features:

• Current CHAT Design Offers:
  • Nominal 12-MW power output
  • 44.5-percent net efficiency (LHV) at rated load and natural gas firing
• Single Digit NOx Emissions from Humidification
• Starts and Loads in Less Than One Minute.
• 80-Percent of Full Load Efficiency at 40-Percent Load
• Output Near Constant with Variations in Ambient Temperature and Elevations
• A Concept Adaptable to Any Combustion Turbine and Capitalizes on Advancements in Combustion Turbine Development
• Potential Performance Improvement by Raising the Inlet Temperature of the High-Pressure, Industrial Expander from 1500F to 2000F
