Shell&tube heat exchanger – is an apparatuswhich operates under pressure and consistsof two separate cavities (tube and shell sides).Divided by the wall of internal tubes, twoflows exchange between themselves withthermal energy without mutual mixing ofworking mediums, if there is a difference intemperatures.

The direction of medium flow in the shell side is controlled by guide baffles for optimal cross-section of the flow. The shape of baffles and the distance between them are selected in accordance with the specified characteristics of STHE, with the purpose of achieving the maximum possible coefficient of heat transfer.

Depending on values of flow velocity and accessibledrops of pressure the heat exchangercan be performed in single- or multi-passmodifications with straight U-tubes. If theradiation losses are excluded, the quantityof the delivered
