Abstract: The method for generating steam with concentrated solar radiation includes the step of heating an absorber by solar radiation and directing a stream of air through the absorber to produce a heated air. The heated air is guided through a heat storage device provided for compensating short-term temperature fluctuations. Steam is generated with the heated air and is thereby cooled. At least a portion of the cooled air is returned to the upstream side of the absorber. The device for preforming the method includes a tower having an air heating device with a solar radiation absorber connected to the top of the tower. An air inlet for introducing air into the air heating device is provided. A steam generator is connected to the tower downstream of the air heating device. A heated air channel is arranged at the tower for guiding the heated air from the air heating device to the steam generator.

Abstract: In a method of cooling and scrubbing a hot gas a hot gas is supplied with a removal pipe into a scrubber. The hot gas is introduced into at least one liquid bath of the scrubber. The hot gas is forcibly dispersed to form small bubbles over at least a portion of a flow path of the hot gas through the liquid bath. The exterior of the removal pipe is cooled with liquid to be introduced into the liquid bath by guiding the liquid along the exterior of the removal pipe countercurrent to the flow of the hot gas in the removal pipe. The device for performing the method has at least one liquid bath. A removal pipe for removing hot gas from the combustion chamber and guiding it to the liquid bath is provided. At least one flow divider with a plurality of openings is arranged in the flow path of the hot gas. A gas removal device is positioned above the liquid bath for removing the cooled gas exiting from the liquid bath.
