STEAM TURBINE EQUIPMENT AND CARRYING-IN METHOD OF FEED WATER HEATER IN STEAM TURBINE EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for shortening a construction time for piping work and carrying-in work of a feed water heater and the like by carrying-in the feed water heater, piping, a rail and a lifting device all as a unit to a construction site.SOLUTION: A carrying-in method of a feed water heater 1 in steam turbine equipment is provided that is used for carrying-in the feed water heater 1 in the steam turbine equipment in which the plurality of feed water heaters 1 for heating feed water to devices using an extracted steam from a steam turbine; piping connected to the plurality of feed water heaters 1 and arranged around the feed water heaters 1; a rail 4 on which the plurality of feed water heaters 1 are movably installed; a lifting device 5 which lifts the feed water heater 1 moving on the rail 4 and having reached a prescribed location and moves the lifted feed water heater 1; and a module frame structure 6 for supporting the lifting device 5 and the rail 4 are integrated in a modular form all as a unit. The carrying-in method of the feed water heater 1 in the steam turbine equipment is characterized in that when the feed water heaters 1 are carried in, the feed water heaters 1 are transported in an integrated and modular state, to a prescribed floor using a carrying-in apparatus and then carried in to a prescribed location via the lifting device 5 and the rail 4.SELECTED DRAWING: Figure 1
