摘要： A process heat recovery system (1) wherein a heat exchanger (2) of shell- and-tube type works either as a boiler or as a boiler feedwater preheater, with boiler water or boiler feedwater circulating on shell-side, so as to cool a hot process fluid circulating on tube-side. The heat exchanger (2) is connected to a steam drum (3) by downcomer piping (12) and riser piping (14) for water circulation between the heat exchanger (2) and the steam drum (3). The heat exchanger (2) receives either the boiler water from the steam drum (3) by the downcomer piping (12), when the heat exchanger (2) works as a boiler, or the boiler feedwater by a boiler feedwater piping (27), when the heat exchanger (2) works as a boiler feedwater preheater. The heat exchanger (2) delivers by the riser piping (14) to the steam drum (3) either boiler water, when the heat exchanger (2) works as a boiler, or preheated boiler feedwater, when the heat exchanger (2) works as a boiler feedwater preheater. The heat exchanger (2) is provided with shell-side plates or baffles (29) for imparting prevailing flow directions to circulating water so that, when the heat exchanger (2) works as a boiler, the shell-side water flow, crosswise the tubes, has a prevailing vertical direction, whereas, when the heat exchanger (2) works as a boiler feedwater preheater, the shell-side water flow, crosswise the tubes, has a prevailing horizontal direction.

摘要： A connection (10) between an uncooled pipe (11) and a cooled double-walled pipe (12) with air space (13) between walls run through by cooling fluid let into the air space through a side passage (14) near the connection. The connection comprises a connection zone (15) having a longitudinal section generally in fork form to have a single tubular end (16) connected to the uncooled pipe and an opposite double tubular end (17,18) to which are connected the corresponding walls (19,20) of the cooled double-walled pipe so that the bottom (21) of the fork constitutes an end closing of the air space. Near the fork between the two walls (17-20) is a baffle member (22) which diverts toward the bottom (21) of the fork the cooling fluid entering the air space through said side passage (14) before the cooling fluid starts to travel along the double-walled pipe.

摘要： A shell-and-tube heat exchanger comprises a shell enclosing a plurality of U-shaped tubes. Each tube is provided with a first portion and with a second portion that are hydraulically connected by a U-bend. The open ends of each tube are connected to a tube-sheet and the tubes are vertically arranged and disposed downward with respect to the tube-sheet. The shell is provided with at least an inlet nozzle for inletting a first fluid and with at least an outlet nozzle for outletting the first fluid. A pressure chamber is connected to the tube-sheet on the opposite side of the shell and above the shell. The pressure chamber is provided with a plurality of nozzles for inletting and outletting at least a second fluid that flows under natural circulation within the tubes, to indirectly perform a heat exchange with the first fluid, and that vaporizes during the heat exchange. The pressure chamber contains a guiding jacket that, at a first end thereof, is sealingly joined to the tube-sheet or the first tube portions and, at a second end thereof that is opposite to the first end, is open. The guiding jacket splits the pressure chamber into a first section, that is enclosed by the guiding jacket and is in communication with the first tube portions, and a second section, that is in communication with the second tube portions. The first section and the second section are in communication each other by means of the open end of the guiding jacket. The first section is provided with a liquid level, located below the open end, and therefore with a vapour chamber, located above the liquid level.

摘要： An apparatus (10) for assembling concentric spiral coils for exchangers comprises a support zone (11) which is intended to receive the spiral coils arranged concentrically on top of each other and an insertion device (12) which inserts one at a time the spiral coils towards the support zone (11). Motorized roller means (13) cause the axial peripheral rotation of the spiral coil during insertion thereof into the support zone (11) such as to obtain a combined screwing movement within the support zone and above the spiral coils already inserted into the support zone. A vibration may be applied during insertion in order to facilitate the operation.
