A pumping device for a steam retrieving device is provided to pump water after the pressure of steam and the pressure of the water are lowered, and to protect a connection portion from vibration when high-pressure steam or high-pressure water are delivered from one part to another part. A heat retrieving unit(10) retrieves sensible heat and latent heat from discharged steam. A circulation pump(20) pumps water from the heat retrieving unit into a steam boiler. A temporary storage drum(30) temporarily stores water from the heat retrieving unit such that an amount of pumped water and a pumping pressure of the circulation pump are uniformly maintained. The temporary storage drum lowers high-pressure steam and high-pressure water. A water hammering preventing unit(40) prevents the damage of connection parts among a waste steam discharge line(21), the retrieving unit, the temporary storage drum. |
