(57) Abstract:

The method and the plant can be used in energy when receiving electric power. Air from the atmosphere through the compressor is fed to the camera interaction, there is injected energy source, the resulting mixture is passed through a turbine connected to a generator. Moreover, to the input of the compressor discharge air temperature from -10C to -70C, and camera interaction is injected through the device for spraying water water in the form of fine sprays with droplet size not greater than 0.2 mm, the power Plant is supplied with water and sealing and/or insulation. The invention allows to prevent environmental pollution and improve the efficiency of power generation. 2 S. and 1 C.p. f-crystals, 2 Il.

The invention relates to the field of energy, in particular to systems generate electricity, can be used as a backup energy source.

Gas turbine way to generate electricity is known: (see Polytechnical dictionary, publishing house "Soviet encyclopedia", M. 1976, S. 101). The known method is that the air from the atmosphere through the compressor is fed to the camera escaut through the turbine, connected to the generator.

The disadvantage of this method is the large emissions of combustion products into the atmosphere.

Known gas turbine, the method of conversion of heat into electricity, which air from the atmosphere through the compressor is fed to the camera communication (combustion), there is injected an energy source (natural gas or liquid fuel), the resulting mixture of the burned gas and air is passed through a turbine connected to a generator, and then throw the empty mixture into the atmosphere (see thermal engineering, Textbook for universities, M. Energoizdat, 1982, S. 197, prototype).

The disadvantage of the prototype is the pollution caused by the exhaust gases.

This invention eliminates the disadvantages of analogue and prototype due to the replacement of oil, gas or coal in water.

The technical result of the invention is the elimination of air pollution and high efficiency.

The technical result is achieved that the gas turbine way to generate electricity, which air from the atmosphere through the compressor is fed to the camera interaction, there is injected energy source, and the resulting mixture of products usaimage is a temperature in the range -10oC to -70oC, as in the camera of the interaction of injected water in the form of fine sprays with droplet size not greater than 0.2 mm

The essence of the method lies in the fact that sprayed water from natural water bodies (in which the depth of water even in the most severe frosts, has a temperature not below +4oC) in the form of a fine aerosol passes from liquid to ice (snow). Sprayed water, freezing, exudes the warmth of a phase transition of water-ice and heats the air from the external temperature (-10oC - 70oC) to zero degrees. The air, which originally had a lower temperature, increasing the turbine does work, rotating the generator. As emissions are formed harmless mixture of air, snow and ice dust.

The use of water aerosols larger than 0.2 mm is problematic, because the water will not make the phase transition that will lead to icing as cameras interaction and turbine.

This invention will find wide application in several regions of Russia not only as a backup source of electricity, but also as a major, because Russia is one of the coldest countries in the world. In Fig.1 to illustrate the above map raspredeleniya, 1983, C. 315).

Widely known from the same sources of information and a gas turbine plant. Similar and prototype have the same structural scheme. They contain the compressor drive turbine with generator, camera, interaction energy with the air input and output paths, made in the form of pipes. At the same time similar and prototype have the common disadvantages: in the winter, especially in winter, when energy consumption increases, increasing the consumption of expensive fuel, increased air pollution caused by the exhaust gases.

This invention eliminates these drawbacks.

The technical result of the invention is the complete elimination of air pollution and increase efficiency when generating electricity.

Developed a universal small-sized gas turbine power plant, which can be used as a backup for winter conditions, as fixed in cold regions, as the underwater, surface, underground and mobile.

The technical result is achieved in that the gas turbine power plant, containing the compressor drive turbine with generator, camera interaction is ogeno device for spraying water in a fine spray, this device is equipped with a water supply system.

When performing power submersible type, located either on the bottom of the river, or under the earth, it has a system of sealing and insulation.

The invention is illustrated in Fig. 2.

In Fig. 2 shows in section, of a gas turbine power plant in case of permanent use on the bottom of the river.

At the bottom of the river under its ice posted by Luggage interaction in the form of a pipe 1. Inside the tube is placed the compressor 2 with the actuator 3 and the turbine 4, which is attached to the generator 5. To the input flange of the pipe 6 is connected to the pipe 7 for air intake from the atmosphere, and to the output flange 8 attached to the exhaust pipe 9. Between the compressor and the turbine has a nozzle 10, provided with a device for spraying water in a fine spray.

The device operates as follows. After activation of the actuator 3, the compressor 2 sucks on line 7 external cold air (at a temperature of from -10oC to -70oC). At the same time in the camera interaction 1 through injector 10 injects a mist that cools and freezes while the mixture of water and air pass the camera vzaimodeystviya to zero degrees. When heated, the air expands isobarically and passing through the turbine 4, does useful work and is emitted to the outside through the exhaust pipe 9.

About 95% of heat is released during the transition from water to ice, this transition occurs at a temperature of 0oC. Above this value, the temperature in the chamber is almost never rises.

We present data from the gas turbine unit with a capacity of 100 kW for the district of Yakutsk for the case when the temperature is -50oC, the compression ratio of 1.4, useful work And = 2.5 kJ/(CGSC). To create a plant with a capacity of 100 kW, the flow rate of cold air will be 40 kg/s, which is approximately 25 cubic meters of water flow of 3 kg/s

Installation design has the following parameters. Luggage interaction 1 has a diameter of 2 m and a length of 3 meters Specified air flow is carried out at a speed of 15 m/s, so the time the camera is 0.2 C. If the diameter of the drops to take 0.1 mm, the time of freezing is less than 0.1 C. To avoid loss drives the compressor and the turbine, they should be placed on one common axis.

When performing system sealing and/or insulation necessary to consider the possibility of glaciation.

The main condition o placed in water, this condition is satisfied automatically. These problems generally relate to the field of optimal settings for the installation, and are always resolved in the operation of the prototype.
