Heat exchanger layout for an industrial carbon black production facility

摘要

Industrial carbon black production facility (100) with at least one reactor (102) to produce a combustion gas and with a heat exchanger system (1) with a first heat exchanger section (3), for the heat exchange between the flue gas and a fluid, and with a second heat exchanger section (4), for the heat exchange between the flue gas and reaction air for the reactor (102), which can be heated previously through the second heat exchanger section (4), where the first heat exchanger section (3) is designed as a double tube heat exchanger (5), with first tubes (7), respectively one-way, arranged respectively in a first external tube (9), and the second heat exchanger section (4) is designed as a tube bundle heat exchanger (25), with a tube bundle of second tubes (27), arranged in a second tube external (29) that, respectively One way, they are arranged in the outer tube (29), where the combustion gas passes through the first and second tubes (7, 27), where the double tube heat exchanger (5) and the heat exchanger tube bundle heat (25) are arranged vertically, and where the respectively upper ends of the first and second tubes (7, 27) are connected to each other through a pipe (23), where the combustion gas passes by the double tube heat exchanger (5), ascending, and by the tube bundle heat exchanger (25), descending.
