摘要： The invention ECT relates to methods for improving the amount of electricity gained from preferably waste heat by a normal or an organic (ORC) Rankine process with vaporization in several stages, normally three. The waste heat in sensible form is exchanged in at least two in series coupled evaporators to a receiving working fluid (e.g. a refrigerant) that passes at least two of said evaporators, but coupled in parallel. Of the waste heat between the temperature of the heat source and that of the heat sink about 80% can be used for direct electricity generation. An embodiment of the invention uses a radial turbine with a centripetal (inwards) flow direction. The different vapor enthalpies from the said vaporization stages enters a turbine wheel/runner 51 at different outside diameters D2, D2′ and/or with suitable tangential velocities obtained by different guiding vane sets 65, 66 and 67.

摘要： An axial-flow turbine according to an embodiment includes a plurality of nozzle structures and a plurality of blade structures. At least one nozzle structure includes an outer ring diaphragm and an inner ring diaphragm. The outer ring diaphragm and the inner ring diaphragm form an annular opening portion which extends in a circumferential direction therebetween. A nozzle is provided in a portion of a region of the annular opening portion in the circumferential direction, and a closing part is provided in another portion of the region of the annular opening portion in the circumferential direction. The closing part closes this other portion of the region to prevent a working fluid from flowing into this other portion of the region. A closing part medium passage is provided in the closing part and is configured to flow a cooling medium which cools the closing part.

摘要： An improved cycle arrangement for a steam turbine system in which an auxiliary turbine drives a boiler feedwater pump. The turbine system includes a primary turbine driving an electric power generator. The primary turbine includes a high pressure section and a low pressure section. A boiler supplies steam to drive the primary and auxiliary turbines. A condenser recovers exhaust steam from the LP section and a plurality of feedwater heaters preheats condensate collected at the condenser and pumped back to the boiler. The system extracts steam from the HP turbine section for operating the auxiliary turbine. Extracted steam from the auxiliary turbine is isolated from the primary turbine by coupling the steam to a feedwater heater supplied solely from a corresponding extraction point of the auxiliary turbine. The exhaust steam from the auxiliary turbine is coupled directly to the condenser.

摘要： In a combined gas/steam power station plant which consists essentially of a fossil-fired gas turbine group and a steam circuit, with an exhaust heat boiler (11) in between, intercooling and reheat are provided to maximize the efficiency. The gas turbine group consists of two compressors (1, 2), of two combustion chambers (7, 9) and of two turbines (8, 10). Downstream of the first compressor (1), there is an intercooler (3) and on the cool side of this is placed an evaporator (4) which is in effective connection with the intercooler. The steam quantity formed in the evaporator (4) is introduced into a turbine (6) of the steam circuit, the result of this being a first improvement in efficiency. Downstream of the first turbine (8), there is a second combustion chamber (9) in which the exhaust gases from the first turbine (8) are processed to produce hot gases for the second turbine (10) . The large calorific potential still present in the exhaust gases from this second turbine (10) flows through the exhaust heat boiler (11) in which a maximized steam power is produced, the result of which is the second improvement in efficiency.

摘要： The integration of a petroleum refinery, or a petrochemical complex, with an off-site power facility in which the latter provides a vaporizable coolant for vaporization in the former. Vaporization is effected through indirect contact with one or more waste heat streams; the resulting vapors are expanded through a turbine, to a lower pressure, from the resulting motion of which power is generated. In most instances, the process generates more power than its connected load. Preferably, the coolant is indirectly contacted, at elevated pressure, with a plurality of refinery process streams in series and in the order of increasing temperature. Resulting vaporized coolant phases are passed through individual turbines, or through different stages of a multiple-stage turbine.
