Here, the fine dust concentration measurement sensor may have a configuration for measuring the fine dust inside the gas turbine 21 by a light scattering method using a light emitting device and a light receiving device, or may have a known configuration such as an e-BAM.

Therefore, according to the second fine dust concentration measuring apparatus 300, more preferably, the inside of the gas turbine 21, the fine dust removal operation described below by measuring the fine dust concentration in the outside air from which fine dust has been removed by a fine dust removal filter or the like. The accuracy and reliability of the amount of fine dust removal calculated by the apparatus 500 may be improved.

The third fine dust concentration measuring apparatus 400 removes moisture or moisture from heat discharged from at least one of the boiler 22 and the cooling tower 24 of the complex power generation equipment 20 and then removes the fine dust concentration.

Here, to add 50 to 60 parts by weight of the filler to 100 parts by weight of the polymer, the thermal conductivity efficiency is lowered when the filler is less than the part by weight, if the filler exceeds the weight part, the viscosity range can not be maintained, the surface of the pipe Since there is a problem that the workability when coating, it is good to have the critical significance as described above.

In addition, the first filler is the largest of the fillers, and has an average particle diameter in the range of 10 to 30㎛, if out of the range can maintain a suitable viscosity range when mixing with the polymer coating on the surface of the pipe Since the workability can be secured and the surface of the pipe can be maintained smoothly, it is preferable to have the above critical significance.

In addition, the second filler is to fill the space between the polymer and the first filler, the second average particle diameter divided by the first average particle size has an average particle diameter corresponding to 0.17 to 0.26, the average as described above If the particle size does not have a particle size, the thermal conductivity may be degraded due to being unable to contact the first filler and thus having the critical significance as described above.

In addition, the third filler, filling the space between the first filler and the second filler, the third average particle value divided by the first average particle value has an average particle diameter corresponding to 0.09 to 0.11, If it does not have an average particle size, such as the contact with the first filler can be spaced apart and the thermal conductivity may be degraded, it is good to have the critical significance as described above.

In addition, the first filler, the second filler and the third filler is preferably the average value of the short diameter / long diameter is 0.6 to 0.8, when the average value of the short diameter / long diameter does not have such a space between the large filler particles completely filled Since the heat conduction characteristics may be lowered since it is not supported, it is preferable to have the critical meaning as described above.

On the other hand, in the present invention, the third fine dust concentration measuring apparatus 400, the dehumidifying means 430 is further configured at the rear end of the cooling means 420, the moisture of the heat cooled by the cooling means 420 condensation And to be removed while settling.

The dehumidifying means 430 is provided with a plurality of eliminators or chevrons and demister filters which are installed on the inner shear surface of the housing 410 to allow the movement of heat.

Here, the plurality of eliminators or chevrons are continuously arranged with a pitch of 50 mm. If the distance is less than the 50 mm, the rate of heat decreases and the speed of heat decreases and the inside of the housing 410 is reduced. There is a problem that the heat inflow is not well made, and if the gap exceeds 50mm, there is a problem in that the contact area is reduced with heat and the efficiency of condensation and sedimentation of the heat is reduced, according to the numerical limitation as described above It is good to have a critical significance.

On the other hand, according to the present invention, the eliminator or chevron has a problem that corrosion occurs due to the condensation of moisture in the heat when used for a long time, so that the water removal efficiency during the formation of the perforation decreases, so that the coating layer for preventing corrosion It is preferably formed in.

Here, the coating layer may be configured in the same manner as the composite polymer composition applied to the refrigerant circulation pipe.

Therefore, according to the dehumidifying means 430, when the contact with the heat introduced into the housing 410, moisture in the heat can be removed to settle and settle.

In addition, according to the present invention, the refrigerant circulation pipe corresponding to the section of the evaporator of the cooling means 420 in the eliminator, the chevron or the demister filter of the dehumidifying means 430 may have a configuration that penetrates zigzag. Through this, it is good to maximize the effect of removing the condensation by improving the saturation of the moisture in the heat.

White smoke and fine dust particles in heat (mixed air and water vapor) that are installed and configured to cover the upper portion of the exhaust passage structure 130 and move to a cooling state inside the structure 130 and the wall 111 are condensed or condensed. White smoke and fine dust particles formed by the white smoke fine dust filter means 140 is formed in the corresponding portion of the cover body 112 that is matched in a straight line of the exhaust port 11, so that the sedimentation and removal is sedimented Is discharged to the outside of the cover body 112 is discharged to the outlet 150 and the outlet 150 is formed in the stack 161 and the discharge fan is formed inside the stack 161 ( Through 162) Air discharge means 160 and the like so that the process of the inlet, mixing, filtering and discharge of heat in the space (S) between the exhaust port 11 and the outlet 150 is made.
