METHOD AND DEVICE FOR HEATING RAILWAY INSTALLATIONS

摘要

According to the invention, a railway installation (11) is heated by a heat source with the aid of at least one heating pipe (1) that is filled with a working fluid. Said working fluid is heated by means of the heat source in the vicinity of a heat absorption zone (2) of the heating pipe (1), converted into gaseous form and flows in the heating pipe or pipes (1) to the railway installation (11) that is to be heated. The heat of the gas is delivered to said installation (11) from a heat delivery zone (6) of the heating pipe (1) as the gas condenses and then flows back in liquid form in the heating pipe or pipes (1) to the heat absorption zone (2). The heat source is geothermal energy and/or ground water and/or waste water that runs in close proximity to the railway installation (11) to be heated. The heating pipe (1) is configured as a heat manifold (9) in the heat absorption zone (2) and as several heat distribution pipes (6, 7, 9c, 15a, 15b, 16a, 16b) in the heat delivery zone (6), said pipes originating in the heat manifold (9) and running horizontally or approximately horizontally.
