  • This utility model is intended to solve the limits of these hot air or chimney-like towers with a gas turbine inside, due to their height needs, lowering them considerably and at the same time exceeding the power indexes they provide to the power grid. It is known that hot air has its molecules more separated than cold air and that the humidity of the same means that more energy is needed to achieve an ideal expansion of the air, so to solve it, a cold equipment has been incorporated into this tower which is responsible for cooling it before entering the compressor blades. It is also known the need for drinking water that they need in many countries, hence this utility model achieves drinking water derived from condensation by cooling the air to be applied to the combustion zone of the turbine, and in very large quantities Meaningful and profitable.

Only the center is used: shaft, with the compressor and turbine blades.
  • This model includes a cold equipment composed of a boiler or radiator through which a wide coolant circulates through its wide ducts of the many that are on the market, such as the combination of water and ammonia, which heated by the hot air that escapes the blades of the turbine at high temperature, heated by solar irradiation focused on its combustion zone, which we call “solar oven”.

Due to the shape of the plates that make up and occupy the entire interior of the middle area of the tower, it leaves enough evaporation between the plates of the evaporator so that the rising air does not throttle.
  • the shape of the evaporator plates are of lower height in the inner part, inner center of the tower, they rise in height to a place in the middle area of the tower's height, where through “visors” in the part upper of each plate that forms the evaporator, the air raises the moisture formed in the plates of the evaporator, and leads it to the outside of the tower.
  • the previously indicated form of the plates is the ideal form
  • another type of plates is also installed as an alternative in the evaporator, lowering the air speed, increasing the lower diameter of the tower, so that the air velocity would decrease, and since its velocity was not enough to raise the water, it would be collected in the lower part that would fall by the same gravity leading them equally to a general conduit to the outside; if this other system of collecting water was chosen, the shape of the evaporator plates can be of different shapes as long as they adapt to the interior space of the tower, in this case the visors on each plate would not be needed. With this utility model, installations for powers ranging from one kilowatt to more than two hundred megawatts can be made.
