Abstract: The invention relates to a heat exchanger in modular construction, in particular for facilities operated using large load and/or temperature changes, having an external shell and a number of heat exchanger modules, wherein each heat exchanger module, which is either a preheater, evaporator, or superheater module, has an entry manifold, and exit manifold, and meandering pipes, through which the heat-absorbing medium, in particular water, flows from the entry manifold to the exit manifold, and the heat exchanger modules are also situated in a shared external shell, so that they have the same heat-dissipating medium flowing around them, the evaporator modules being connected in parallel via a steam-collecting drum situated outside the external shell.

Abstract: A heat exchanger for generating a steam flow for a solar-thermal power plant, including a casing for receiving a casing-side fluid, pipes arranged within the casing for a pipe-side fluid, and a fluid inlet conduit which is connected to an inlet opening for the casing-side fluid and which encloses at least a part of the pipes in such a manner that the fluid inlet conduit is configured as a preheater and/or a flow director for the casing-side fluid entering the casing, wherein heat is transmitted via the pipes from the pipe-side fluid to the casing-side fluid. The casing-side fluid is water, and the pipe-side fluid is a thermal oil or salt.

Abstract: A heat exchanger erected vertically for generating steam for solar power plants, including: an outer casing with an inlet and an outlet port for a heat-emitting medium; an inlet and an outlet collector for a heat-absorbing medium, said inlet and outlet collectors lying substantially within the outer casing; and a tube bundle within the outer casing with a number of tube layers including continuous tubes, wherein the heat-emitting medium can flow entirely around same and which are designed as flow paths for the heat-absorbing medium from the inlet collector to the outlet collector. The tube bundle is arranged in a meandering manner, wherein the heat exchanger is arranged according to a forced-flow principle so that the heat-absorbing medium is successively pre-heated, evaporated, and superheated so that a superheated steam exits the outlet collector.
