PROBLEM TO BE SOLVED: To provide a steam generation system capable of raising low pressure steam by a comparatively small amount of high pressure steam. ! SOLUTION: The steam generation system comprises: a first steam generation part 4 generating first steam W1; a second steam generation part 2 generating second steam W2 with higher pressure than that of the first steam W1; a first ejector 6 having a first vapor flow outlet 63 and generating third steam W3 with higher pressure than that of the first steam W1 and with lower pressure than that of the second steam W2 using the first steam W1 as suction steam and the second steam W2 as drive steam; a second ejector 7 having a second vapor flow inlet 71 and generating fourth steam W4 with higher pressure than that of the third steam W3 and with lower pressure than that of the second steam W2 using the third steam W3 as suction steam and the second steam W2 as drive steam; and a sixth steam supply line L6 which is branched from a third steam supply line L3 conn |
