FIELD OF THE INVENTION [0001] The present invention relates to a smoke-free window and a smoke-

The present invention relates to a smoke exhaust window, and more particularly, to a smoky ventilator installed in a building, in which a rapid air flow due to attracted air is generated outside a window, The present invention also relates to a flue gas treating method and a flue gas treating method for a flue gas furnace capable of enhancing the smoke exhaust performance of a flue gas window.

As cities become more sophisticated and integrated, the construction of large buildings, high-rise buildings and complexes are rapidly proceeding, and buildings that are vulnerable to fire are increasing. Accordingly, there is a great demand for effective fire prevention measures for safety of life.

Especially, it is emphasized the importance of related equipment for control of smoke, which causes great disruption to evacuation and digestion in case of fire and which poses the greatest threat to human life safety. For example, in a fire accident, more than 70% of human casualties are being investigated by smoke. Moreover, it is expected that the rise of high-rise buildings, large spaces, multiplexes, and large underground spaces will be very rapid, and establishment of effective smoke countermeasure technology is required.

In the case of domestic buildings, smoke exhaust facilities are to be installed in the buildings included in the designated use in buildings of 6 floors or more by "Article 51 (2) of the Enforcement Decree of the Building Act". The specific installation standards of such smoke-free facilities are specified in "Article 14 of the Rules for Building Facilities Standards, etc.", and here, as shown in FIG. 1, installation regulations and usage types for smoke- .

Specifically, the installation regulations of the fireplace window proposed in the "Article 14 of the Rules for Building Facilities Standards, etc." include the minimum area of the fireplace window, the method for calculating the area of the fireplace window, the vertical position for installation and the way of opening.

On the other hand, in high-rise buildings, air currents are generated around the buildings due to the ambient wind speed, and various pressure distributions appear along the surface of the buildings. Specifically, the pressure of the wind on the building can be expressed by the following equation (1).

Especially, when the wind is blown in the high-rise building and the pressure is formed on the surface of the building, the smoke-reducing effect of the window is decreased. According to the related research, it was considered that the smoke performance of the flue gas window is significantly lowered in the entire floor of the building when the outside air wind speed is increased.

Accordingly, it is necessary to develop a technology for ensuring the natural flue gas emission performance of the smoke through the smoke exhaust window when the ambient air velocity of the building has a fire.
