PRESSURELESS HEAT STORAGE DEVICE FOR WATER TEMPERATURES OVER 100 °C

摘要

The invention relates to a heat storage device (1) for storing and providing heat energy accruing with the power generation by means of a fluid, comprising at least a first (2) and a second chamber (3). The first chamber (2) is disposed above the second chamber (3) and a conduit (4) disposed substantially in the chambers (2, 3) connects an upper region (5) of the first chamber (2) to a lower region (7) of the second chamber (3), such that in operation there are no temperature differences and thus also no buoyancy forces between end points of the conduit (4). The invention further relates to an installation for combined heat and power, and to a method for storing and providing heat energy accruing with the power generation.
