Humidity regulation in gas turbine power stations

TTR high-performance dehumidifiers increase the profitability

Gas turbine power stations significantly contribute to the coverage of short-term peak loads. A sophisticated humidity regulation helps to prevent the breakdown of individual gas turbines due to corrosion and problems with the electronics. 

Across the globe the climate change, increasingly scarce resources and ever-increasing energy costs call for solutions for a more environmentally friendly and resource-saving power generation. Even though the operating costs of a gas and steam power station are comparatively high due to the low efficiency factor, gas turbine power stations are generally considered a reliable temporary technology for the transition of our energy production to renewable energies. A great deal of the energy input is lost through waste heat and gas turbine cooling.

Therefore it is all the more important to ensure an optimum usage of the energy input and to eliminate potential sources of incidents that could compromise the economical operation or a gas turbine power station or – in the worst case – lead to the failure of individual gas turbines, boilers or pumps. For example due to excessively humid process and regeneration air!

One thing is for sure: Breakdowns will cost you. Gas turbine power stations have to be ready for operation at all times to cover short-term peak loads in the energy supply. If it takes several minutes to start up the turbines, failures and malfunctions can entail tremendous costs!

Securing the operational readiness increases the profitability

A great amount of supply air is required for the smooth operation of gas turbines. Particularly important factors are the air quality and an optimally regulated humidity level. Should the air not be optimally dehumidified, harmful condensate can form inside the plant. Possible consequences are rust, corroded components and failures of the sensitive electronic system.

Trotec's solution: stationary TTR industrial desiccant dehumidifiers

Further application examples for air dehumidification

  • Environmental simulation climate chamber

    In climatic chambers and wind tunnels three factors need to be simulated at the best possible rate: air temperature, wind strength and humidity. For the latter, the automotive industry needs dehumidifiers, which also perform well at dew points below 0°C, as well as high-performance desiccant dehumidifiers.

  • Drying hygroscopic bulk material

    Varying and too high humidity values can ruin the pourability of powders and granules – and thus entail high consequential costs. In order for hygroscopic bulk material not to go lumpy nor to block hauling paths, the entire air in the chemical and pharmaceutical production must be pre-dried. Using adsorption dryers of the TTR series that's no problem.

  • Drying after silo cleaning

    After the cleaning of storage containers and silos you have to count on them to be fully dried for new bulk material to be protected against moisture from the beginning. And since drying can be effected in a quick and economical manner, we advise decision makers from the chemical and pharmaceutical industry to consider our high-performance dryers of the TTR series.

  • Dehumidification in hotels

    A suitable room climate is a prerequisite for the well-being of hotel guests. If the air in the room is too warm or humid, it appears to be stale and muggy. Often damages appear at the building structure and interior within a short period of time. Wallpaper will be dotted with mould stains, curtains and clothes as well as linen become damp and musty and – if it comes to the worst – mildew runs...
