HEAT UTILIZATION SYSTEM

PROBLEM TO BE SOLVED: To provide a heat utilization system which does not require atmospheric emission of steam in a condition where there is a great difference between the temperature at an exit side path of a superheater for producing superheated steam from the steam that has been generated in a boiler for generating steam by utilizing heat of a given heat source, and the temperature in a steam collector, the system being provided with; a plurality of steam generating facilities each having the boiler and the superheater; the single steam collector which is connected to the exit side path of each of the superheaters; a heat load, which is connected to the steam collector, for utilizing heat held by the superheated steam transferred thereto from each of the superheaters; and a condensate path, which is located downstream of the heat load, for condensing and returning the used steam discharged from the heat load to the boiler. SOLUTION: Steam recovery paths R4a, R4b are provided for branching and connecting the exit side paths R1a, R1b of the superheaters 6, respectively, to the condensate path R3 without being interposed by the steam collector 11.
