Abstract

PURPOSE:To make it possible to minimize heat loss in the generation heating value of a gas burner and hence enhance thermal efficiency by installing an insulation means between a heat exchanger which is installed to the downstream side of a gas burner and an exhaust passage which is installed to the downstream side of the heat exchanger, and what is more, which exhausts combustion exhaust gas of the gas burner outside. CONSTITUTION:When a gas combustion device is operated, the amount of heat generated by a gas burner 3 is absorbed in water flowing in a heat exchanger 1 and combustion exhaust gas which has turned to a lower temperature after having passed through the heat exchanger 1, is discharged outside by way of an exhaust gas passage 21. Since the exhaust gas passage is designed to adjoin the heat exchanger 1 at that time, the combustion exhaust gas tends to rod the gas burner 3 of the amount of generated heat. However, there is installed an insulation means between the exhaust gas passage 21 and the heat exchanger 1, thereby minimizing the thermal conductivity between the exhaust gas passage 21 and the heat exchanger 1. Therefore, it is difficult to transmit thermally the amount of heat generated by the gas burner 3 to the combustion exhaust gas of the exhaust gas passage and hence minimize heat loss resultant from that.

In the water pipe (11) on the lower stage side, the action of mainly condensing the combustion exhaust gas of the gas burner (3) and absorbing its latent heat is performed. That is, in the water pipe (11) on the lower stage side, since the water flow is on the upstream side and the water flow temperature is low, mainly by further cooling the sensible heat deprived and cooled combustion exhaust gas to a temperature below its dew point temperature. Drain is generated and the latent heat at that time is absorbed by the water in the water pipe (11). Then, the combustion exhaust gas that has passed through the heat exchanger (1) is exhausted to the outside from the exhaust port (2) through the exhaust passage (21). At this time, the can body
Since the heat insulating material is provided in the heat insulating chamber (5) between the (6) and the exhaust passage (21), and the heat conductivity of that portion is small, the heat generation amount of the gas burner (3) is It is difficult to transfer heat to the combustion exhaust cooled below the dew point. In this embodiment, since the present invention is adopted in the water heater of the type in which not only the sensible heat of the combustion exhaust gas but also the latent heat is positively absorbed by the heat exchange section to efficiently absorb the thermal energy of the combustion exhaust gas, other The exhaust temperature is lower than that of the conventional type, and the effect of suppressing the heat transfer of the generated heat amount to the combustion exhaust is particularly advantageous.
