Method and device for increasing the energy efficiency of a power plant

Abstract

The invention relates to improving the efficiency or the energy balance of a power plant. Here, the heat content waste heat from the power plant is employed in such a way that the waste heat is fed into a first and/or a second thermoacoustic machine. In the first thermoacoustic machine a work output is generated with the aid of the waste heat and as a result of the thermoacoustic effect, which is employed elsewhere in the power plant, for example to operate a compressor. The second thermoacoustic machine is likewise used for cooling a working fluid by utilizing the waste heat and the thermoacoustic effect.
