PROBLEM TO BE SOLVED: To enhance a heat recovery amount from an exhaust gas, by using a plurality of still bodies different in steam pressures, as the still bodies of an exhaust gas boiler, and to enhance versatility of obtained steam obtained by pressure-rising steam of low vapor pressure. SOLUTION: This stem system includes the upstream still body 3 passed with the exhaust gas, to generate the steam using heat of the exhaust gas, the downstream still body 5 passed with the exhaust gas after passed through the upstream still body 3, to generate the steam of pressure lower than that of the upstream still body 3, and a pressure rising mechanism 50 for rising pressure of the steam from the downstream still body 5, by the steam from the upstream still body 3. The pressure rising mechanism 50 is an ejector 51, for example. COPYRIGHT: (C)2011,JPO&INPIT |
