Abstract: A heat transfer arrangement for heating a working fluid by means of a flowing hot fluid comprises a fluid channel for carrying the flowing hot fluid, a pipe bundle arranged in the fluid channel for carrying the working fluid, wherein the pipe bundle comprises a number of pipeline segments running parallel to each other in a longitudinal direction and a carrying structure permanently connected to the fluid channel for holding the pipe bundle in the fluid channel. The pipeline segments are each supported on the carrying structure on at least a first non-moving bearing point and on at least a second bearing point separated from the first bearing point in the longitudinal direction and having clearance movement in at least one direction.
