案請求範囲第２項記載の給水加熱装置。[Scope of Claim for Utility Model Registration] (1) A heat exchanger for heating feed water is installed in addition to the flue of the LNG thermal power plant, and the exhaust gas is guided from the flue to this heat exchanger to increase the heat exchange temperature of the exhaust gas. The temperature is lowered to below 100 degrees, water vapor in the flue gas is condensed, and its latent heat of vaporization is used. After heat exchange, the cooled flue gas is reheated and returned to the flue, reducing the smoke exhaust effect of the flue. A feed water heating device designed to recover waste heat without waste heat. (2) Utility model claim 1 in which feed water is heated by bringing it into direct contact with exhaust gas in a packed tower, wet wall tower, wet shelf tower, etc. for waste heat recovery without using the heat exchanger mentioned in paragraph 1.
Feed water heating device as described in section. (3) In an attempt to recover waste heat, neutral or alkaline intermediate heating water is brought into direct contact with the exhaust gas, the pH of the intermediate heating water after heat recovery is adjusted, and the heating medium is guided to a heat exchanger for heating the feed water. A feed water heating device according to claim 2 of the utility model.
