Abstract:
An industrial production plant including at least one reactor for producing a flue gas and including a heat exchanger system having a first heat exchanger section for heat exchange between the flue gas and a fluid and a second heat exchanger section for heat exchange between the flue gas and reaction air for the reactor, which can be preheated by the second heat exchanger section. The first heat exchanger section is configured as a double-tube heat exchanger with first tubes each arranged one-way in a respective first jacket tube, and the second heat exchanger section is configured as a tube bundle heat exchanger with a tube bundle of second tubes arranged in a second jacket tube and each arranged one-way in the jacket tube.

Claim (Index 11):
A carbon black production plant comprising:\n at least one reactor for producing a flue gas and comprising a heat exchange system having a first heat exchange section for heat exchange between the flue gas and a fluid and a second heat exchange section for heat ex-change between the flue gas and reaction air for the reactor, wherein the reaction air can be preheated by the second heat ex-change section, wherein said first heat exchange section is designed as a double-tube heat exchanger comprising first tubes each arranged in a single-path configuration in a respective first casing tube, and wherein said second heat exchange section is designed as a tube-bundle heat exchanger comprising a tube bundle which is arranged in a second casing tube and which includes second tubes each arranged in a single-path configuration in the casing tube, said first and second tubes being adapted to have the flue gas flow through them, wherein said double-tube heat exchanger and said tube-bundle heat exchanger are arranged vertically, wherein the respective upper ends of the first and second tubes are connected to each other via a tube conduit, the flue gas flowing through the double-tube heat exchanger is an ascending direction and through the tube-bundle heat ex-changer in a descending direction.
