PURPOSE:To enable the stable driving by providing a thermosiphon steam generator utilizing a high temperature exhaust gas generated from a reformed gas forming device and a thermo-siphon steam generator utilizing the holding heat of a coolant exhausted from a cooling mechanism. CONSTITUTION:A high pressure steam generated in a thermo-siphon steam generator X provided on the exhaust line of a reformer A is reached to an ejector 2 through a steam superheater 12 to provide a driving energy to natural gas. On the other hand, a thermo-siphon steam generator Y for generating a low pressure steam consists of a water cooling tank for cooling a fuel battery C as a steam generator Y1 and a steam drum 11 as a hot water drum Y2. Thus, as a large quantity of qualitatively adjustable low pressure steam is generated, this can be supplied to the lower stream side of the ejector 2 from the viewpoint of keeping a necessary amount of steam to natural gas. Hence, the stable driving is made possible. |
