Proposed Turbine Inlet Air Cooling for MLNG processing plantDato Mat Isa
Turbine Inlet Air Cooling (TIAC) is an established and proven power augmentation technology for GT power plants. It cools the compressor inlet air to boost GT generator power output and efficiency. The technologies adopted for TIAC includes mechanical chilling, evaporative cooling and fogging.
TIAC Is a group of technologies and techniques consisting of cooling down the intake air of thegas turbine. The direct consequence of cooling the turbine inlet air ispower output augmentation.
I have worked more than four years on gas turbine performance and how it can be enhanced by "Gas Turbine Inlet Air Cooling". That led to dedicating my BS and MS theses to the topic. Once I presented a summary of gas turbine inlet cooling (principles, methods and issues) when I was a Rotating Equipment Engineer at Monenco Iran Consulting Engineers…

Industrial gas turbine (air cooling & sealing sys) 5thNguyen Phuong Dong
The document discusses the cooling and sealing air systems of industrial gas turbine engines. It describes the purpose of cooling air systems as ensuring parts do not absorb heat from the gas stream and controlling engine temperatures. Cooling air flows around components like the combustor, turbine, and accessories. Turbine blades have intricate internal cooling designs to withstand high temperatures. Sealing air systems use methods like labyrinth seals to prevent oil leakage and control airflows around the turbine disc. The document outlines the components and operation of cooling and sealing air systems, with the goal of demonstrating knowledge of these important gas turbine systems.

The document summarizes research on gas turbine cooling systems. It examines injection cooling methods, including forward and backward injection. Studies compare the cooling effectiveness of different injection directions and blowing ratios. Backward injection leads to more uniform cooling across the span and higher overall effectiveness compared to forward injection. Conclusions determine that backward injection improves film cooling performance on flat surfaces by promoting stronger interaction between the coolant jet and mainstream flow.
The document discusses a turbine inlet air chilling project in Saudi Arabia that installed the world's largest thermal energy storage tank in terms of capacity. The project uses a 10,000 ton refrigeration cooling plant and 30,000 cubic meter thermal energy storage tank to chill inlet air for 10 gas turbines. During off-peak hours, the cooling plant fills the tank with chilled water, and during peak hours this stored chilled water is used to cool inlet air and recover over 150 MW of lost power production. This thermal energy storage system is described as the equivalent of having two additional gas turbines without needing to install physical turbines.

Data center cooling techniques are evolving along with rapidly changing usage patterns. Cooling systems now account for 38% of energy consumption in data centers. Failure of cooling systems is critical and can damage servers within minutes, resulting in downtime and revenue losses of millions per day for some industries. The priorities are maintaining redundancy and uptime through various cooling solutions and technologies, including free cooling, indirect cooling, adiabatic solutions, and new innovations like modularization and direct liquid cooling. Proper thermal management rather than just cooling is now the goal to efficiently manage heat levels.
