A gas turbine compressor consumes half or more of the work produced by the expansion turbine. Therefore, an increase in compressor efficiency can produce a significant rise in the power output and fuel efficiency of a gas turbine. Wet compression systems are designed to increase your gas turbine power output at a fraction of the…
What is Gas Turbine Inlet Fogging/Inlet Air Cooling? Gas turbine inlet air fogging has been used for more than twenty-five years and has been employed on more than 1300 gas turbines around the world. Fogging consists of spraying very small water droplets into the inlet airflow to cool the air by evaporation. Inlet fogging increases…
In recent years, the number of oil refineries has dropped by half, so to meet growing demand for fuel, existing refineries have added capacity. But with increased emissions regulations, any expansion is closely scrutinized, so refineries must continually find ways to lower their energy usage and reduce their environmental impact. The Challenge An L.A. based…
The Challenge Summer in Italy is beautiful, but hot. Hot air has a lower mass than cold air. The difference in mass reduces air flow. This becomes problematic for certain products, such as turbines, which depend on a steady airflow to deliver maximum performance. The Solution Mee Industries supplied a fog cooling system to help…
After doing a net present value analysis of the money we would have to invest and how much power we would recover, fogging turned out to be really, really good in terms of dollars per kW. It made a lot of sense to our owners. — Pablo Cortes Oseguera Engineering and Maintenance Manager Gradually losing…
The Electricity Minister of Libya asked APR Energy to provide four mobile gas turbines totaling 250MW to aid their overtasked power generation and transmission system. APR was challenged by the dry Libyan desert climate which caused power output and efficiency losses in the gas turbines. Temperatures rose to 90°F (32°C), often exceeding 100°F (38°C) during…
