Heat exchanger structure for condensating gas-fired boiler

Abstract

An arrangement structure of heat exchangers in a condensing gas boiler is provided, which includes a casing and a combustion chamber therein. The arrangement structure of heat exchangers includes: a present heat exchanger slantly arranged with a predetermined slope 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 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 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. 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.

Description

technical field [0001] The present invention relates to a heat exchanger arrangement structure for a condensing gas boiler, and more specifically, the present invention relates to a heat exchanger arrangement structure for a condensing gas boiler that maximizes the heat transfer area, forms sensible heat and The condensing condition improves the heat exchange efficiency and ensures the compactness and corrosion resistance of the whole device. Background technique [0002] Boilers used in general households, public buildings, etc. are used for heating and hot water. According to the form of fuel provided, such boilers are roughly divided into oil-fired boilers and gas-fired boilers. [0003] If you compare oil-fired boilers and gas-fired boilers with the same capacity, in terms of purchase price, the price of oil-fired boilers is lower than that of gas-fired boilers, but gas-fired boilers have the advantage that their fuel consumption is lower than that of oil-fired boilers....

AI Technical Summary

Problems solved by technology

[0007] However, although aluminum, or stainless steel is excellent in corrosion resistance, on the other hand, due to low thermal efficiency, the size of the heat exchanger itself must be increased in order to ensure the same amount of heat, so that it is impossible to make the entire condensing gas boiler compact Shortcomings

[0008] In addition, since the flow direction of the exhaust gas is the same in the conventional condensing gas boiler, it is installed so that the areas of the heat exchangers in the sensible heat part and the latent heat part are different in the vertical direction, but there is a disadvantage of reducing the heat exchange efficiency
