摘要： A heat exchanger incorporating a heat pipe apparatus, said heat pipe apparatus comprises an evaporative pipe group (16) disposed within a flow of a heating fluid; a first condenser pipe group (20) located away from and lower from said evaporative pipe group and disposed within a flow of a fluid to be heated; and first passage means (18) for connecting said evaporative pipe group with said condenser pipe group and through which a working medium passes between said both pipe groups. Said heat pipe apparatus further comprises a bubble generator (43) disposed within a bypass passage through which a portion of said heating fluid branched off from said heating fluid flows so as to generate bubbles, whereby said working medium is forcedly circulated throughout said first passage means.

摘要： PROBLEM TO BE SOLVED: To prevent vibration of a heat-transfer pipe due to fluid elastic vibration in an exhaust heat recovery boiler and to prevent damage to a vibration proof support due to drift of exhaust gas. SOLUTION: A heat-transfer pipe 12 is allocated in a flue where a combustion exhaust gas passes, and a vibration-proof support 27 bundling the heat-transfer pipe, at a plurality of points, in pipe-axis direction or the heat-transfer 12 is fitted. Since a moment generated by torsion of heat-transfer pipes is dispersed for each split body by fitting the vibration-proof support 27, split in plural numbers, in the direction right to pipe-axis of the heat-transfer pipe 12, occurrence of excessive vent stress due to moment is prevented. Since no excessive bending stress occurs with such part of the vibration-proof support 27 as near a header of the heat-transfer pipe 12, the vibration-proof support 27 except for the part near the header of the heat-transfer pipe is desired to be allocated in split in the direction right to the axis of the heat-transfer pipe.

摘要： PROBLEM TO BE SOLVED: To provide a vertical type waste heat recovering boiler, economical and simple in arrangement, by a method wherein the number of casing penetrating part is reduced and the number of employing places of a special expansion joint as well as external communicating pipes is reduced. SOLUTION: A heat transfer tube group 2, arranged in the horizontal direction, and a steam drum 3, for receiving fluid from the heat transfer tube group 2 to separate air from water, are arranged in a casing 6 forming an exhaust gas flow passage. The steam drum 3 is arranged in the exhaust gas flow passage whereby the communicating pipe 4 of the fluid and a water descending pipe 5, which are between the heat transfer tube group 2 and the steam drum 3, can be received in the casing 6 and not only a communicating pipe at the outside of the casing, which was necessary in conventional technique, can be removed but also the installing number of casing penetrating parts for a communicating pipe and the like, which require air-tight seal, can be reduced.

摘要： PURPOSE:To prevent mixture of heating fluid and cooling fluid and to reduce the number of valves controlled during switching by a method wherein a heating fluid flow passage and a cooling fluid flow passage are formed to each of adsorbing and desorption devices. CONSTITUTION:Heating fluid flows out from a heating source 24 and flows through a heating inlet pipe 6 to a heating pipe 6A of an adsorbing-desorption device 3A by means of a heating switching valve 7. After the heating fluid heats an adsorbent 2 on an outer peripheral part, it is returned through a check valve 8A and a heating outlet pipe B to the heating source. Cooling fluid flows from a cooling source 40 through a cooling water inlet pipe 9 to a condenser cooling water pipe 4C and is caused to effect desorption by means of the adsorbing-desorption device 3A to cool and condense desorption steam of a working medium flowing through a desoprtion steam passage 15A to a part 4A of a condenser 4. After cooling fluid condensing desorption steam to adsorb the heat thereof is slightly increased in temperature, it flows through a cooling switching valve 10 to an adsorbing desorption device cooling water pipe 6D of an adsorbing-desorption device 3B to cool and adsorbent 2 under an adsorbing motion with which the outer peripheral part of the adsorbing desorption device 3B is filled.

摘要： PURPOSE:To make it possible to shorten starting time by providing the structure that working fluid, which flows out at least one of stem turbines, is reheated by a heat exchanger tube so as to be supplied to the steam turbine of the next stage. CONSTITUTION:After steam of working fluid, which flows out a steam turbine 3a of high pressure side, is reheated to specified high temperature by absorbent solution which is boiling in a boiler 1 or working fluid steam, it is supplied to a steam turbine 3b of low pressure side, and dryness is sufficiently enhanced. As the temperature of the absorbent solution in the boiler 1 is higher than the saturation temperature of the working fluid steam of the same pressure, the temperature of reheated steam can be set sufficiently high comparing with a reheating system by combustion gas. Meanwhile, the temperature condition of a heat exchanger tube 25 concerning reheating doesn't exceed the temperature of the absorbent solution or the working fluid steam. Therefore restriction isn't imposed on starting condition, so that starting time can be sufficiently shortened comparing with the reheating system by the combustion gas.
