Abstract

PURPOSE:To contrive an improvement of thermal efficiency by recovering even latent heat obtained when overheated vapor within combustion gas is cooled down to a temperature lower than a dew point for condensation by making the combustion gas flowing from a heat exchanging component of an instantaneous boiler pass through an air permeable solid. CONSTITUTION:When a main burner 10 in a gas water boiler is caused to be burnt and water is supplied to a heat exchanger 14 through a water pipe 13, the water which flows through the water pipe 13 is heated by a very hot combustion gas at the main burner through the heat exchanger 14 and discharged in warm water from a hot water discharge opening 6. At this time, combustion gas whose temperature is reduced to some extent by passing through the heat exchanger 14 is then caused to be passed through an air permeable solid 18 made of, for example, plural layers of stainless steel wire nettings. With this, the permeable solid 18 is heated to a very hot temperature, and on the other hand a temperature of the combustion gas is reduced causing condensation of overheated vapor within the gas on the surface of the solid 18, and the solid 18 is heated with latent heat discharged at that time. Heating efficiency is improved through radiation of heat possessed by the solid 18 to the heat exchanger 14.
