PROBLEM TO BE SOLVED: To provide a steam supply system capable of reducing energy loss of a whole system by effectively utilizing steam for superheating.SOLUTION: A steam supply system 10A sends high-pressure superheated steam St2-1, medium-pressure superheated steam St2-2B and low-pressure superheated steam St2-3B to steam utilization equipment 11A to 11C by superheating high-pressure saturated steam St1-1, medium-pressure saturated steam St1-2 and low-pressure saturated steam St1-3. The steam supply system 10A comprises: a superheater 15A which superheats the medium-pressure saturated steam St1-2 using the high-pressure superheated steam St2-1; another superheater 15B which superheats the low-pressure saturated steam St1-3 using the medium-pressure superheated steam St2-2B; a high-pressure steam discharge pipe L16-1 which sends steam St3-1 used by the superheater 15A to the medium-pressure superheated steam St2-2A; and a medium-pressure steam discharge pipe L16-2 which sends the steam St3-2 used by the superheater 15B to the low-pressure superheated steam St2-3A. |
