Heat exchanger arrangement for an industrial manufacturing plant.

摘要

The present invention relates to an industrial manufacturing plant (100), which includes at least one reactor (102) for generating combustion gas and a first for heat exchange between the combustion gas and a fluid. And a heat exchange system (1) having a second heat exchange part (4) for exchanging heat between the combustion gas and reaction air for the reactor (102). The reaction air can be preheated by the second heat exchange section (4). The first heat exchanging section (3) has a double pipe heat exchanger (5) having a first pipe (7) arranged in one direction in each first casing pipe (9). The second heat exchange section (4) is arranged in the second casing pipe (29) and is arranged in one direction in the second casing pipe (29). This is configured as a tube bundle heat exchanger (25) having a bundle of tubes (27). The combustion gas can flow through the first pipe (7) and the second pipe (27). The double tube heat exchanger (5) and the tube bundle heat exchanger (25) are arranged vertically. The upper ends of the first pipe (7) and the second pipe (27) are connected together via a conduit (23). The combustion gas flows upward through the double tube heat exchanger (5) and flows downward through the tube bundle heat exchanger (25).
