Abstract: Elongated ceramic heat exchange units are arranged with each such unit axly oriented and all arranged parallel to each other in a ring surrounding the compressor, gas turbine and combustion chamber of a gas turbine motor. Each heat exchange unit has a multiplicity of rectangular slot channels through alternate ones of which the hot exhaust gas and the compressed air supply flow in counter-current. The cross sections of these channels all have their long dimension disposed substantially radially with respect to the axis of symmetry common to the principal components. The respective inputs for the two sets of channels are both from the inside of the ring arrangement but at opposite ends of each heat exchanger element; whereas the exit openings are in the end faces of the heat exchanger elements.

Abstract: A nuclear power-generating installation comprises three power-generating bines which are operated by three partial gas streams heated in separate passages of a nuclear reactor. After traversing the power-generating turbines the partial gas streams are cooled in respective recuperative heat exchangers to recover residual useful heat therefrom and are combined into a lesser number of gas streams each of which is subjected to at least two compression stages with at least one intervening cooling stage in which all of the gas is combined to flow as a total gas stream through at least one such cooler. Following the last compression stage the gas is again subdivided into three partial streams for preheating in the aforementioned recuperative heat exchangers before traversing the nuclear reactor for the main heating.
