Abstract

The steam power station includes an accumulator for storing heat drawn from the operating steam cycle during slack operating periods when the power network demand on the station is low, and restoring the heat to the steam cycle at peak or high-demand periods, to adapt the station to a variable demand network. The transfer of heat between the operating installation of the station, which includes a steam turbine, and the accumulator, is made by way of a heat-transfer fluid which is in heat-transfer relation with the steam of which at least a part has done mechanical work in the turbine. The heat-transfer fluid is reversibly circulated in heat-transfer relation with the steam in such a way that the heat-transfer from the steam to said fluid occurs at substantially the same temperature as the transfer from said fluid to the steam. The installation can also heat feed water returning to the steam generator by tapping off live steam for said heating at the outlet from the generator. The installation can have apparatus for separating into liquid and dry steam partially expanded steam issuing from the turbine, the liquid from that apparatus being vaporised by heat from a heat accumulator supplied with heat from the heat source of the installation; all the liquid is vaporised during high-demand periods while in slack periods all the liquid is restored to the feed water circuit to the steam generator.
