Patent attributes
An arrangement structure of heat exchangers in a condensing gas boiler is provided, which includes a casing provided with a combustion chamber therein, and a gas burner provided in the lower portion of the combustion chamber. The arrangement structure of heat exchangers in a condensing gas boiler includes: a present heat exchanger slantly arranged with a predetermined slope with respect to a horizontal axis on a transverse cross-section in the casing; a latent heat exchanger disposed in parallel with the present heat exchanger, in the same area as that of the present heat exchanger in the upper portion of the present heat exchanger; a condensed waterspout provided in parallel with between the present heat exchanger and the latent heat exchanger, whose one end contacts one of the inner wall surfaces of the casing and whose other end is disposed spaced from the other of the inner wall surfaces thereof; and an exhaust gas flowing plate provided in parallel with the outer wall of the latent heat exchanger, whose one end is spaced from one of the inner wall surfaces of the casing and whose other end contacts the other of the inner wall surfaces of the casing in order to induce condensed water and exhaust gas to flow in an identical direction. Thus, the heat transfer area is maximized, and present heat and condensing conditions are made to improve a heat exchanging efficiency, and to accomplish compactness and corrosion resistance of the boiler.
