    摘要： There is disclosed a steam plant 10 comprising a boiler 18 arranged to generate steam; a reverse osmosis unit 14 having a RO inlet 46 arranged to receive inflow water and a permeate outlet 58 in fluid communication with the boiler 18 through a permeate line 60, wherein in use the reverse osmosis unit 14 receives inflow water and generates permeate which is provided to the boiler 18 through the permeate line; a blowdown vessel 20 in fluid communication with the boiler 18 so as to receive hot blowdown water from the boiler 18, and a blowdown vessel outlet 84 which is in fluid communication with the RO inlet 46 through a blowdown return line, wherein in use the blowdown vessel 20 generates cooled blowdown water; and a flow controller 86 having a temperature sensor arranged to monitor the temperature of the cooled blowdown water. In use, if the temperature of the cooled blowdown water is below a threshold then the flow controller 86 operates to direct the cooled blowdown water to the RO inlet 46. There is also disclosed a method of operating a steam plant and a method of upgrading an existing steam plant.
