| 摘要 |
The invention relates to a power plant system (1), comprising: a heat-generating unit (10) for providing thermal energy; a water-steam circuit (20), which is connected to the heat-generating unit (10) in regard to heat transfer; an electricity-generating device (30), which can be energised by the thermal energy conducted in the water-steam circuit (20) in order to generate electricity; and a thermochemical accumulator (40), which is connected to the water-steam circuit (20) likewise in regard to heat transfer. The thermochemical accumulator (40) is connected to an exhaust gas line of the heat-generating unit (10) in regard to heat transfer, and the thermochemical accumulator (40) has two tanks (41, 42), which are connected to each other in regard to fluid flow. A thermochemical storage material (45) is arranged in a first tank (41), and the first tank (41) can be supplied with heat by thermally conditioned exhaust gas (120) of the heat-generating unit (10), and the second tank (42) is connected in regard to heat flow to a heat exchanger (44), by means of which the second tank (42) can be supplied with low-temperature heat at a temperature level of at most 150 °C. |
