PROBLEM TO BE SOLVED: To obtain an air heating device free from accumulation of condensed water inside the device. SOLUTION: A steam supply pipe 2 is connected to an inlet header 8 of a heat exchanger 1. A steam ejector 4 is interposed in the steam supply pipe 2. A simple steam trap 7 comprising a float 14 and an orifice plate 15 is disposed inside a fin tube 6. A condensed water accumulation container 10 and a steam trap 5 are connected to an outlet header 9 of the heat exchanger 1. The condensed water inside the fin tube 6 quickly flows down into the condensed water accumulation container 10 due to pressure gradient formed by the steam ejector 4, and the condensed water is not accumulated inside the heat exchanger 1.
