Description

なお、図７に示すように、吸気加熱装置６の代わりに抽気管４５を備えているものもある。
抽気管４５は、圧縮機１１で圧縮された吸気の一部を熱交換器３４に導く配管であり、吸気加熱装置６の代わりに抽気管４５を備えているものでは、抽気管４５を介して熱交換器３４に暖かい（熱い）吸気が供給され、抽気管４５を介して圧縮機１１から導かれた吸気と、ダクト１５の入口１５ａから取り込まれた吸気（ここでは０℃の吸気）とを熱交換させて、ダクト１５の入口１５ａから取り込まれた吸気に熱を与えて、ダクト１５の入口１５ａから取り込まれた吸気が（ここでは１０℃まで）加熱されることになる。 Note that, as shown in FIG. 7 , some of them include a bleed pipe 45 instead of the intake air heating device 6.
The extraction pipe 45 is a pipe that guides a part of the intake air compressed by the compressor 11 to the heat exchanger 34. In the case where the extraction pipe 45 is provided instead of the intake air heating device 6, the extraction pipe 45 is connected via the extraction pipe 45. Warm (hot) intake air is supplied to the heat exchanger 34, and intake air introduced from the compressor 11 through the extraction pipe 45 and intake air taken in from the inlet 15a of the duct 15 (here, 0 ° C. intake air). Heat is exchanged to give heat to the intake air taken in from the inlet 15a of the duct 15, and the intake air taken in from the inlet 15a of the duct 15 is heated (up to 10 ° C. in this case).
