ThermoCharger
Combustion turbines lose efficiency and power, as inlet air temperature increases. This means that on hot days, turbine power output is significantly decreased from rating conditions (ISO-59°F). Chilling the inlet air with exhaust heat powered refrigeration keeps the turbine output at full rated power, at all ambient conditions. THERMOCHARGER delivers turbine inlet air chilling with no capacity penalty compared to using electric powered refrigeration. Unlike evaporative inlet air cooling (misting) the Thermocharger performance is not humidity dependant and can achieve lower inlet air temperatures. During cold days, the same Thermocharger can be used to provide anti-icing.

Key Features
System Layout
TIAC System Diagram The turbine exhaust warms an aqueous ammonia solution in heat exchanger coils (HRVG) located within the exhaust gas path. The ammonia is then separated in the rectifier to produce a nearly pure refrigerant vapor, which is condensed, reduced in pressure, and then allowed to expand, producing chilling in the turbine inlet air cooling coils (TIAC) located in the inlet air stream. The refrigerant vapor from the cooling coils is reabsorbed by the aqueous ammonia bottoms product from the rectifier (an exothermic process that requires cooling), and is re-pressurized for return to the HRVG. Thus, the process is a closed loop. InstallationsTurbine Inlet Air Chilling at Power Plant
