The invention relates to a method for recovering heat from intermittently and instantaneously released blow-off steam charges. The method is carried out using a container (6) with an internal volume (2), provided with an inlet (7) and an outlet (10). The method comprises the steps of supplying a blow-off steam charge (Sh) via the inlet (7) to the container (6) and collecting the latter in the internal volume (2) of the container. In this case, the charge (Sh) may be held in a gravitational field. It is possible to recover energy from a portion of the blow-off steam charge (Sh) by condensation thereof. The condensation results in a stream from said portion to an outlet (10) which is at a lower gravitational potential. Via the outlet (10), it is possible to discharge a portion of the charge (Sh) from the internal volume (2) of the container (6) at a lower gravitational potential. This can be effected by supplying a subsequent blow-off steam charge (Sh) to the internal volume (2), thereby expelling the charge (Sh) which is present via the outlet (10). During heat recovery air is drawn in via the outlet (10).
