Abstract

889,424. Nuclear power plants. MARGUERRE F. May 5 1958 [May 3, 1957; Aug. 24, 1957], No. 14272/58. Class 39(4) [Also in Group XIII] To match the constant output of a nuclear reactor to the varying load of an electrical grid, an externally fired superheater is used in conjunction with tegenerative (or " drop ") accumulators, in addition to the usual feed water displacement accumulators. Steam from the reactor heat exchanger is superheated by the upstream superheater gases and fed to a turbine. Steam for the accumulators is bled from the turbine after partial expansion and passed through a superheat-recuperator to the regenerative accumulators. On discharge it passes through the superheater waste gases before entering the turbine at intermediate stages. Any remaining heat in the superheater gases is used to supplement the preheater for the turbine condensate. To match the accumulator steam temperature to that of the input points and to divert heat to the preheater when the accumulator superheater is not needed the amounts of heat reaching each part of the superheater can be varied. More than one accumulator may be used, operating at different pressures and on different turbine tapping points. This reduces the size of the tapping points. A separate turbine may be used for discharging the accumulators: In discharge, hot water flows from the regenerative accumulator 21 through a valve 23 to an expansion vessel 24 and is returned to the accumulator. Steam from the expansion vessel goes to the turbine 29 which acts as an energy-recovering throttle device, and is controlled by valve 23 only. The state of discharge of the accumulator is known from its average temperature. For charging, steam is bled from the main turbine through valve 31a. Water flows from the accumulator through line 26 and pump 32 to the expansion vessel, and is returned by pump 25 through lines 34 and 22 to the accumulator. The flow of water is thermostatically controlled to give the correct full-charge temperature. The superheater would be inserted in line 27. The turbine may have a valve to by-pass some rows of blades for high-load working. The condensate may be preheated in the main turbine circuit before re-circulation. Charging may also be done by putting a surface preheater in line 31.
