    • PURPOSE:To provide the subject labor-saving apparatus having decreased energy loss by constantly inspecting the openings of differential pressure regulation valves of pressure-regulator group of a drier drainage apparatus, and providing a setting device to set the inlet steam pressure of a medium pressure group without changing the pressure difference of the pressure-regulator group. CONSTITUTION:The valve openings of differential pressure regulation valves 10, 11 of a pressure-regulator group in an apparatus for the utilization of regenerated steam of a drier are constantly inspected by a medium-pressure group steam pressure setting device 18 for regulating the inlet steam pressure of a medium pressure group 16. When the regenerated steam of the pressure-regulator group 7 escapes to the side of a heat-exchanger 19, the regenerated steam pressure of the pressure-regulator group 7 is judged to be set to a high level compared with the inlet steam pressure of the medium pressure group 16 and the setting of the pressure is changed to decrease the inlet steam pressure of the medium pressure group 16. The inlet steam pressure and the regenerated steam pressure of the pressure-regulator group 7 and the inlet steam pressure of the medium pressure group 16 are constantly maintained in optimum balanced state to maximize the effective utilization of the regenerated steam.
