IMPROVEMENTS IN OR RELATING TO STEAM RAISING PLANT
A scheme is given for a dual pressure steam raising plant for reactor power plants, especially those of the Calder Hall type in which heat transfer fluid (CO/sub 2/) can be circulated by steam. In the scheme, the gaseous coolant is passed through the steam raising unit and then is passed back into the reactor via a gas blower. The unit employs a dual pressure cycle in which water is passed into two steel drums connected to evaporators and superheaters in the unit; steam from one drum is high-pressure steam (HP). while steam from the other is low-pressure steam (LP). HP drives the gas blower by means of a back pressure turbine and then is discharged into the LP cycle in the unit. HP and LP from the superheaters are fed into a distant turbo-alternator which comprises two turbines, a small one for HP and a large one for LP. (D.L.C.)
