The present invention relates to a steam recovery apparatus which increases the thermal efficiency of a boiler system by completely recovering the remaining heat of exhaust steam by spraying a groove into a water supply nozzle formed therein.

In general, a steam boiler system is a thermal power system that uses a high temperature and high pressure steam obtained by heating water as a working fluid, a thermal power system or a nuclear power system that generates power, and a heating or cooling system. Air conditioning and heating system.

The steam boiler system includes a water supply tank for supplying water, a steam boiler for heating water supplied from the water supply tank, a steam use unit for using steam produced in the steam boiler for heating various buildings, and the steam. It is formed as a discharge part to discharge the steam used in the use part.

As described above, the general steam boiler system has a problem in that the fuel efficiency is increased and the cost increases as the thermal efficiency is greatly reduced because the latent heat and the heat of the exhaust steam discharged from the steam use part are not recovered.

As described above, a steam boiler system of the related art devised to solve the problem will be described below with reference to FIG. 1.
