<P>PROBLEM TO BE SOLVED: To provide a chimney structure and a waste-heat recovery system, for executing the heat recovery from exhaust gas, in order to use the heat of exhaust gas from a compact boiler, a simple boiler, a garbage incineration facility or the like, for other applications. <P>SOLUTION: The chimney structure 1 includes: a casing 10, which functions as a flue of exhaust gas of a boiler 70; a heat transfer pipe 20, which functions as a liquid flow passage inside, introduces the liquid from the outside of the casing 10 into the casing 10, receives the heat from exhaust gas in the flue, and discharges the liquid outside the casing 10 after the temperature of the liquid is raised; and a liquid introduction control means 30, which controls the introduction of the liquid into the casing 10, on the upstream side of an insertion port 11 of the heat transfer pipe 20 into the casing 10; wherein any liquid circulation impairing means for impairing the liquid circulation is not present on the downstream side of the insertion port 11 of the heat transfer pipe 20 into the casing 10, and the inside of the heat transfer pipe 20 is not pressurized with liquid. <P>COPYRIGHT: (C)2012,JPO&INPIT |
