Turbine Inlet Cooling

The patented Multistage Evaporative Cooling System (MECS) will cool the inlet air entering natural gas combustion turbines (CTs) to <= 59°F in most climatic regions thereby cost effectively increasing CT efficiencies and resulting power production by 5 to 25% while using less energy. The primary reason Turbine Inlet Cooling (TIC) is implemented is to enhance the power output of natural gas combustionturbines (CTs) when the outside ambient air temperature is above 59°F. The International Standards Organization (ISO) rated capacities of all CTs are based on the standard outside ambient air conditions of 59°F at 14.7 psia (sea level). For example, TIC industry data shows that by cooling the outside ambient inlet air from 100°F to 59°F prevents the loss of 27percent of the rated generation capacity.

  • MECS is scalable from 10 to over 1000 tons
  • Delivers 57°F cool water, 53°F cold air, or both at the same time based on ASHRAE tables for Phoenix summer design conditions for cooling applications
  • Has comparable first costs to mechanical refrigeration systems
  • Provides 60 to 85% less power usage/energy savings compared to traditional mechanical refrigeration systems
  • Incorporates NO compressors and uses NO refrigerants.
  • Compressed Air Systems

    Compressor work increases proportionally as inlet air temperature increases. Cooler air is denser and provides more mass for each compression cycle with no additional power use. Lower inlet air temperature will result in less compressor work. Use outside air for cooling reciprocating and lubricant-free screw compressors when it is cooler than indoor air. Locate compressors so radiator stays clean and free of oil, saw dust and debris. This may also help keep the compressor cool. Reducing the inlet air temperature reduces energy used by the compressor. In many plants, it is possible to reduce inlet air temperature to the compressor by taking suction from outside the building. Energy Savings Potential As a rule of thumb, each 3 °C will save 1% compressor energy use.
