In another conventional example, a fuel mixer (Patent Registration No. 10-0301676) was mounted in a band form to increase the efficiency of the far infrared ray material. However, the fuel and the far-infrared ray are not in direct contact with each other.

In addition, the conventional patent (No. 10-0079027) uses the fuel-activating minerals and the ultrasonic wave transmission module device as a solution to the above problems, but it has problems such as nozzle clogging and internal tank damage.

Hereinafter, detailed structures and operations of the present invention will be described in detail.

According to the present invention, there is no need for a separate additional device for increasing the power generation capacity and efficiency of the gas turbine power generation system, and only the Inlet Air Filter 4 composed of the far-infrared functional nanofiber nonwoven fabric 22 is installed in the gas turbine intake device, To solve the problems of

Far infrared rays originate from sunlight (light) and cause radiation, resonance, and vibration. When far infrared rays are applied to fuel and air, the natural vibration of the hydrocarbon molecules of the oil resonates and the amplitude of the vibration is amplified. The vibrations of the molecules in the air are amplified and the air and the fuel are mixed smoothly. As a result, the surrounding air of fuel particles separated by carbon and hydrogen can be completely burned.

Each atom constituting every object has its own electromagnetic force depending on the arrangement state of the electrons arranged at the outermost part of the atomic structure. Depending on the magnitude of the electromagnetic force, the attraction force for determining the binding state of the atom and the molecule is changed, Depending on the strength of this force, the state of the corresponding object is divided into a solid, a liquid, or a gas. This manpower mixes the fuel particles, which consist of several fuel molecules, in the air-enclosed form, so that the air molecules are not in full contact with the individual fuel molecules, resulting in poor fuel efficiency. Generally, this phenomenon is referred to as cluster (cluster). For example, if the cluster distribution of water is represented by the O-NMR half-width by means of a nuclear magnetic resonance apparatus, it is possible to compare finely divided water with non-cleaved water.

Table 1 shows the experimental results to determine whether the far infrared ray is activated or deactivated to confirm the cleavage of water or air. Far-infrared function The non-woven filter of nanofibers shows that the relaxation time of half-width (Hz) progresses very slowly at 55.58 Hz at maximum, compared with tap water and general nanofilter, so that the far-infrared energy is continuously generated. Therefore, according to the present invention, the far-infrared-activated air is mixed with the fuel by radiative resonance action to be finely divided into fine particles such as molecules and atoms, and the density of oxygen is gradually increased while fusing with air. Finally, the activated fuel to which a large amount of oxygen is attached is transferred to the combustion device 300 to be completely burned. Therefore, the present invention can increase the efficiency of the engine due to complete combustion and reduce fuel consumption.

The two-stage separator 6 has a function of finally separating and discharging fine water droplets containing salt in the incoming air. The discharge pipe (7) separates moisture, saline and foreign substances discharged from the first and second separators and discharges them to the outside. The sound absorber 8 serves to reduce noise due to high-speed air flowing into the gas turbine.
