Device for evaporation of low-boiling liquefied gases

The invention relates to a device for evaporating low-boiling liquefied gases, in particular for use in an internal combustion engine on a ship, wherein the gas is heated by means of a heating medium circulating in an intermediate circuit. According to the invention, the first heat exchanger (1) is configured as a double-tube heat exchanger with an inner tube (14) for the passage and heating of the gas and an outer tube (15) for the passage of the heating medium, wherein the gas and the heating medium are guided co-currently through the first heat exchanger (1) and the inner tube (14) and the outer tube (15) of the first heat exchanger (1) are configured concentrically and are oriented vertically.
