VAPOR DEVICE

A steam device includes a high-temperature member (1) and a low-temperature member (2). One surface of the high-temperature member (1) is exposed to high-temperature steam (3), and the other surface is cooled by cooling steam (4) having a temperature lower than the high-temperature steam (3). The lo...

Beschreibung
Zusammenfassung:	A steam device includes a high-temperature member (1) and a low-temperature member (2). One surface of the high-temperature member (1) is exposed to high-temperature steam (3), and the other surface is cooled by cooling steam (4) having a temperature lower than the high-temperature steam (3). The low-temperature member (2) is disposed to face the high-temperature member (1) with a passage for the cooling steam (4) therebetween and is formed of a material having a heat resistance lower than that of the high-temperature member (1). The steam device has at least one high-reflectance, film selected from a first high-reflectance film (6), which is formed on the surface of the high-temperature member (1) which is exposed to the high-temperature steam (3) and has a higher reflectance with respect to infrared rays than the high-temperature member (1), and a second high-reflectance film (10), which is formed on the surface of the low-temperature member (2) facing the high-temperature member (1) and has a higher reflectance with respect to infrared rays than the low-temperature member (2).
