| 20080289588 | PROCESS FOR STEAM HEAT RECOVERY FROM MULTIPLE HEAT STREAMS - Disclosed is an apparatus and process for recovering heat from multiple hot process streams without multiplying instrumentation. Each hot process stream is indirectly heat exchanged with a water circuit which leaves and feeds a steam drum. Heat is added to the steam drum through the addition of water heated outside of the steam drum. The heated liquid and vapor water is heated in heat exchangers decoupled from the steam drum. The water circuits are arranged in parallel with each other and feed a single steam drum to provide a steam product of a desired pressure for which only one set of instrumentation is needed. | 11-27-2008 |

| 20130112156 | HEAT EXCHANGER FOR GENERATING STEAM FOR SOLAR POWER PLANTS - 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. The energy for the pre-heating, evaporation, and superheating is essentially provided by the heat transfer from the heat-emitting medium to the heat-absorbing medium. The tube layers are arranged in such that the tubes of the individual tube layers are aligned to lie next to one another in the horizontal direction, with the directions of flow of the heat-absorbing medium being opposite in the horizontally adjacent tube sections which are arranged transversely to the central axis of the outer casing, and such that the tube layers are vertically adjacent. Each tube layer is formed from an equal number of tubes. | 05-09-2013 |
