Abstract
This invention is intended to lower a temperature of a high-temperature exhaust gas to a desired temperature, while effectively suppressing adhesion of melting components and dusts in the high-temperature exhaust gas onto an inner wall of a cooling tower. For this purpose, a method of the present invention comprises an introduction step of introducing a high-temperature exhaust gas into a cooling tower through a gas duct, and a cooling step of sparging cooling water to the high-temperature exhaust gas in the cooling tower to cool the high-temperature exhaust gas. During the introduction step, the high-temperature exhaust gas is introduced into the cooling tower through the gas duct comprising two gas duct lines, in such a manner that respective portions of the high-temperature exhaust gas from the two gas duct lines become equal to each other in flow velocity and flow volume. Further, respective axes of the two gas duct lines are arranged so as to extend in directions opposed to each other and approximately orthogonal to an axis of the cooling tower, when viewed from a direction along the axis of the cooling tower.
