<P>PROBLEM TO BE SOLVED: To provide a multi-stage pressure rising type steam injector device that avoids heat loss of steam supplied from a steam supply port, thereby, enhances the efficiency and can be made compact. <P>SOLUTION: A multi-stage pressure rising type steam injector device 1 includes steam injectors 2A, 2B, 2C configured such that a cooling water supplied from a cooling water supply port 8 is subjected to pressure rising by a pressure of steam supplied from a steam supply port 6 and is injected from an injection port 7, wherein an injection port 7 of the steam injector 2A on the upstream side is connected to the cooling water supply port 8 of the steam injector 2B, the injection port 7 of the steam injector 2B is connected to the cooling water supply port 8 of the steam injector 2C to form an injector row 3A, the injection port 7 of the steam injector 2C is connected to a cooling water supply object, and steam supply means are connected to the steam supply port 6 of each of the steam injectors 2A, 2B, 2C. Each of the steam injectors 2A, 2B, 2C has the steam supply port 6 on the upstream part thereof, has the injection port 7 on the downstream part thereof and has the cooling water supply port 8 on a middle part between the steam supply port 6 and the injection port 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
