COMBINED combined-cycle plant with a parallel scheme of work

摘要

The utility model is designed for use in power and can be used to create steam and gas units (PTU) increased efficiency through gas turbine superstructure steam turbine units (PTU) in the modernization of existing units. The technical problem solved useful model is to reduce the capital cost of the gas turbine unit and the compressor reducing the energy expended by the compressor drive.; Said technical problem is solved in that the known combined cycle plant with a parallel circuit works, comprising a steam turbine plant comprising a boiler 17, equipped with a three-stage platen superheater 19 and connected thereto a steam turbine 8 from the regeneration system, a gas turbine unit comprising a compressor 1 with gas turbine 3 and the combustion chamber 2 installed at the outlet of the gas turbine heat recovery boiler 5 with 6 heating complementary surfaces similar to the surface of the steam heating Boiler according to the utility model, further provided with a conduit 16 connecting the selection of a steam turbine with a combustion chamber of a gas turbine installation, as well as conduit 20 that connects the output of a pair of the recovery boiler 5 to the conduit between the first and second stages of platen superheater 19 of the steam boiler 17.; 1 Fig.
