<p>A waste heat recovery apparatus comprising a high-temperature unit including a high-temperature casing having an inlet through which an exhaust gas is introduced into the unit and an outlet through which the exhaust gas is discharged from the unit, a set of heat exchanger tubes arranged in the high-temperature casing, and a dry-type cleaner for removing dust on the heat exchanger tubes, a low-temperature unit including a low-temperature casing having an inlet through which the exhaust gas is introduced into the unit and an outlet through which the exhaust gas is discharged from the unit, a set of heat exchanger tubes arranged in the low-temperature casing, and a flush-type cleaner for removing dust on the heat exchanger tubes by spraying flushing water on the tubes, an intermediate duct connecting the outlet of the high-temperature unit and the inlet of the low-temperature unit so that the exhaust gas from the high-temperature unit is passed into the low-temperature unit through the intermediate duct, an exhaust duct connected to the outlet of the low-temperature unit so that the exhaust gas is discharged from the low-temperature unit through the exhaust duct, a by-pass duct connecting the intermediate duct and the exhaust duct, first damper for controlling the flow of the exhaust gas from the intermediate duct to the low-temperature casing, and second damper for controlling the flow of the exhaust gas from the intermediate duct to the by-pass duct.</p> |
