Abstract

A crossflow heat exchanger which is capable of being excellently used over a wide range from an exhaust gas high-temperature region to an exhaust gas low-temperature region below the acid dew point. In a conventional heat exchanger, such as a steel pipe type air preheater, when a gas including a large amount of a corrosive component is employed, it is necessary to prevent low-temperature corrosion and, therefore, it is not possible to lower the exhaust gas temperature below the acid dew point; consequently, this involves a disadvantageously low heat recovery rate for the heat exchanger. The crossflow heat exchanger according to the present invention employs a heat exchanger element of ceramics, which is free from low-temperature corrosion, whereby it is possible to lower the exhaust gas temperature and thereby to increase the heat recovery rate. The heat exchanger may be applied to a marine air preheater (particularly for a low-temperature portion), a gas heater for a desulfurizer and similar devices.
