摘要： A trap apparatus of condensate water according to the present invention comprises: a neutralizing part including an inlet through which condensate water is introduced, an internal space for containing a neutralizing agent for neutralizing the introduced condensate water, and a condensate water passage through which the condensate water that was neutralized by the neutralizing agent in the internal space is discharged; a discharge part including a storage space for storing the condensate water which is directly or indirectly introduced through the condensate water passage, an outlet which is open in a circular shape so as to discharge the stored condensate water, and a spherical ball capable of closing the outlet by being seated on the outlet, wherein the ball is spaced from the outlet by buoyancy of the condensate water when the condensate water is contained in the storage space above a critical water level, such that the condensate water can be discharged through the outlet, and the condensate water can be neutralized simultaneously with discharging of only the condensate water without exhaust gas.

摘要： An exhaust duct includes an upper duct being open at opposite ends thereof and a lower duct being open at a tip end thereof. One end of the upper duct is connected, inside an enclosure of a water-heating device, to an exhaust adaptor disposed on the enclosure, and an opposite end of the upper duct communicates with the tip end of the lower duct. The upper duct is connected to the lower duct so as to be slidable along a reference direction in which the lower duct extends from the tip end of the lower duct, and the upper duct is configured to be separated from the exhaust adaptor by sliding along the reference direction.
