The present invention aims to provide a latent heat exchanger in a condensing boiler, which has no limit in the usage of a burner, comprises an upward combustion condensing boiler with a simple installation structure, reduces the exhaust resistance of a combustion product, and allows seamless discharging of condensed water generated from the latent heat exchanger so as to enhance the efficiency of latent heat recovery. To this end, the condensing boiler of the present invention comprises: a sensible heat exchanger for absorbing combusted sensible heat from the burner; the latent heat exchanger for absorbing the latent heat in water vapors in the combustion product that has been heat-exchanged in the sensible heat exchanger; an exhaust hood for discharging the combustion product that has passed through the latent heat exchanger; and a condensed water outlet port for discharging the condensed water generated from the latent heat exchanger, wherein the combustion product combusted in the burner is passed through the sensible heat exchanger, perpendicularly raised to the latent heat exchanger, descended in a slanted manner on the outer side, creating an acute angle with a horizontal surface, for heat-exchanging in the latent heat exchanger, and then perpendicularly raised and discharged from the exhaust hood. |
