Title: HEAT EXCHANGER ADAPTED FOR THE PRODUCTION OF CARBON BLACK
Abstract:
A heat exchanger (30) for an apparatus for the production of carbon black is disclosed. It comprises a first heat exchanging part (31 ) comprising a first chamber (33) enclosed by a jacket (34), a lower end wall (35) and an upper end wall (36). Tubes (37) adapted for flow of combusted gas therein are arranged in the first chamber. The heat exchanger also comprises a second heat exchanging part (32), comprising a vertically arranged second chamber (42) adapted for flow of combusted gas therein, the second chamber (42) being surrounded by a first shell (43) adapted for allowing heat transfer to a gas to be preheated flowing on the outside of the first shell (43). The heat exchanger also comprises a conduit (52) adapted for flow of said gas to be preheated from the second heat exchanging part (32) to the first heat exchanging part (31 ).
