Abstract

Układ siłowni cieplnej łączący cechy obiegu turbiny parowej i obiegu turbiny gazowej, zwłaszcza dla tzw. "suchych" czynników roboczych składa się z: wymiennika pełniącego funkcję wytwornicy pary, sprężarki, regeneratora, wymiennika wysokotemperaturowego do przegrzewania pary, urządzenia ekspandującego, skraplacza i pompy zasilającej, a istota układu polega na tym, że proces sprężania czynnika odbywa się częściowo lub całkowicie w pompie, a tylko częściowo lub wcale w sprężarce, natomiast ciepło przegrzania czynnika wypływającego z ekspandera wykorzystuje się w regeneratorze do podgrzewania czynnika za sprężarką i w wymienniku pełniącym funkcję wytwornicy pary do wytwarzania pary. Pompa zasilająca (IV) zwiększa ciśnienie cieczy roboczej i podaje ją do wytwornicy pary (VI), gdzie kosztem ciepła odbieranego od przegrzanej pary czynnika roboczego następuje wytworzenie pary. Para z wytwornicy (VI) kierowana jest do sprężarki (VII), gdzie następuje dalszy wzrost ciśnienia czynnika roboczego. Ze sprężarki czynnik roboczy podgrzewany jest w regeneratorze (VIII) kosztem ciepła przekazanego od czynnika wypływającego z ekspandera (I). Następnie czynnik kierowany jest do wymiennika wysokotemperaturowego (V), gdzie zwiększa się jego temperatura kosztem ciepła przekazanego od czynnika grzewczego. Po wyjściu z wymiennika wysokotemperaturowego (V) czynnik dopływa do ekspandera (I), gdzie ekspanduje i oddaje moc do napędu generatora elektrycznego (II). Następnie czynnik roboczy dopływa do regeneratora (VIII), w którym oddaje swoje ciepło do podgrzewania pary czynnika wypływającego z wytwornicy (VII). Z regeneratora (VIII) czynnik wpływa do wytwornicy pary i oddaje swoje ciepło do wytworzenia pary. Z wytwornicy pary (VI) czynnik wpływa do skraplacza (III) i wykrapla się, a powstałe skropliny dopływają do pompy (IV). Istota układ siłowni cieplnej łączącego cechy obiegu turbiny parowej i obiegu turbiny gazowej, zwłaszcza dla tzw. "suchych" czynników roboczych polega na tym, że układ łączy w jednym obiegu zalety obiegu Rankine'a turbiny parowej i obiegu Braytona turbiny gazowej: ciepło dostarczane jest do obiegu w zakresie wysokich temperatur, jak dla obiegu turbiny gazowej, a oddawanie ciepła z obiegu odbywa się przy niskiej temperaturze, jak dla obiegu turbiny parowej, a ponadto zmniejszona jest praca procesu sprężania czynnika roboczego. Układ odznacza się znacznie wyższą sprawnością od stosowanych obecnie odpowiednich obiegów turbin parowych lub obiegów turbin gazowych.A thermal power plant system combining the features of a steam turbine cycle and a gas turbine cycle, especially for the so-called "dry" working media consists of: an exchanger serving as a steam generator, compressor, regenerator, high temperature exchanger for steam overheating, expanding device, condenser and feed pump, and the essence of the system is that the process of compressing the medium takes place partly or completely in pump, but only partly or not at all in the compressor, while the heat of superheating of the medium flowing out of the expander is used in the regenerator to heat the medium behind the compressor and in the exchanger acting as a steam generator for generating steam. The feed pump (IV) increases the pressure of the working liquid and feeds it to the steam generator (VI), where steam is produced at the expense of heat removed from the superheated steam of the working medium. The steam from the generator (VI) is directed to the compressor (VII), where the working medium pressure increases further. The working medium is heated in the regenerator (VIII) from the compressor at the expense of heat transferred from the medium flowing out of the expander (I). Then, the medium is directed to the high-temperature exchanger (V), where its temperature increases at the expense of heat transferred from the heating medium. After leaving the high-temperature exchanger (V), the medium flows to the expander (I), where it expands and gives power to the drive of the electric generator (II). Then the working medium flows into the regenerator (VIII), in which it gives off its heat to heat the steam of the medium flowing out of the generator (VII). From the regenerator (VIII), the factor flows into the steam generator and gives away its heat to produce steam. From the steam generator (VI), the factor flows into the condenser (III) and condenses, and the resulting condensate flows into the pump (IV). Essence of a thermal power plant system combining the features of a steam turbine cycle and a gas turbine cycle, especially for the so-called "dry" operating factors consist in the fact that the system combines the advantages of the steam turbine Rankine cycle and the Brayton gas turbine cycle in one circuit: heat is supplied to the circuit in the high temperature range, as for a gas turbine cycle, and heat transfer from the circuit takes place at a low temperature, as for a steam turbine circuit, and in addition the work of the compression of the working medium is reduced. The system is characterized by a much higher efficiency than currently used appropriate steam turbine or gas turbine circuits.
