<p><P>PROBLEM TO BE SOLVED: To provide a steam system which enables comparatively low-temperature exhaust gas whose recovery as steam is difficult to generate steam even when passed through an exhaust gas steam boiler. <P>SOLUTION: Exhaust gas is passed into an exhaust gas hot water boiler 2 to make hot water whose temperature is increased due to the same gas circulate through a heat pump 3. In the heat pump 3, steam is generated by using hot water from the exhaust gas hot water boiler 2 as a heat source. The steam is pressurized by a pressurization mechanism 4. Preferably, the heat pump 3 is an absorption type heat pump and the pressurization mechanism 4 is a steam ejector 15. In order to stably start the steam ejector 15, it is preferable to open an ejector steam supply valve 17 and then open an ejector suction valve 19. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
