Condensing combustion apparatus

A condensing combustion apparatus comprising:

• an upward combustion burner (20);
• a sensible-heat exchanger (40) which absorbs sensible combustion heat generated by the burner (20);
• and
• a latent-heat exchanger (50) which absorbs latent heat of steam included in a combustion gas which has passed the sensible-heat exchanger (40),
• wherein the sensible-heat exchanger (40) and the latent-heat exchanger (50) have the same lateral widths and are configured as fin-tube heat exchangers having common structures, and
• wherein a flow path through which the combustion gas, which has passed the sensible-heat exchanger (40), flows upward is formed on one side portion of the latent-heat exchanger (50), a flow path through which the combustion gas, which has passed the one side portion of the latent-heat exchanger (50), flows downward corresponding to a direction in which condensed water falls is formed on a middle portion of the latent-heat exchanger (50), and a flow path through which the combustion gas, which has passed the middle portion of the latent-heat exchanger (50), flows upward and is discharged, is formed on another side portion of the latent-heat exchanger (50),
• wherein a condensed water collector (70) for inducing condensed water to discharge is provided between the sensible-heat exchanger (40) and the latent-heat exchanger (50), and
• wherein the condensed water collector (70) is slantly disposed between a top end of the other side of the sensible-heat exchanger (40) and a bottom end of the one side of the latent-heat exchanger (50) and induces the combustion gas, which passes the sensible-heat exchanger (40) and flows upward, to move toward the one side portion of the latent-heat exchanger (50),
• wherein a vertically upward plate (74), which extends upward and is coupled to a tube (53) of the latent-heat exchanger (50) to prevent a lateral movement of the combustion gas between the middle portion and the one side portion of the latent-heat exchanger (50), is formed at the condensed water collector (70).

• wherein a flow path guide member (80) for inducing the combustion gas, which passes the one side portion of the latent-heat exchanger (50) and flows upward, to move toward an area of the middle portion of the latent-heat exchanger (50) is provided at a top of the latent-heat exchanger (50),
• an exhaust path (60) which comprises an upper cover (61) and a flue (62) is provided at the top of the latent-heat exchanger (50), and
• wherein the flow path guide member (80) comprises a slant plate (81) slantly disposed between a top end of the other side of the middle portion of the latent-heat exchanger (50) and a bottom surface of the upper cover (61) and a fixing plate (82) integrally formed on the slant plate (81) and coupled to the bottom surface of the upper cover (61).
