B. Koks — sein kann. Eine solche Rückführung ist in F i g. 2 gestrichelt dargestellt. Das gasförmige Arbeitsmittel des primären Wärmekraftprozesses — z. B. Helium (F i g. 1) oder Verbrennungsgase (Fig.2 und 3) — wird in Gasturbinen 2 entspannt Das entspannte Arbeitsmittel wird im offenen Kreislauf nach außen abgegeben (Fig.2) oder im geschlossenen (Fig. 1) oder teilgeschlossenen (F i g. 3) Kreislauf durch Gebläse 3 umgewälzt und auf die obere Druckstufe des Wärmekraftprozesses verdichtet - in Schaltung nach Fig.3 zur Regelung der Eintrittstemperatur in die Gasturbine 2. Den Brennkammern 1 in Fig.2 und 3 wird durch Gebläse 4 Frischluft zugeführt Die Abwärme- dieses ersten Wärmekraftprozesses wird dem Brennstoff-Umwandlungsprozeß 6 indirekt über Wärmetauscherflächen (F i g. 1 und 2) oder direkt durch Zusatz von Verbrennungsgasen (Fig.3) zugeführt Kombinationen dieser Teilprozesse sind möglich.In Fig. 1 to 3 are different variants of the Gas turbine plant according to the invention shown: In the case of the plant according to FIG. 1 serves as the primary energy source 1 the nuclear heat of a high-temperature nuclear reactor, in the systems according to Fig. 2 and 3 the Combustion heat of a fossil fuel, which is also a re ^ ktionsproduct of the downstream Fuel conversion process - e.g. B. Coke - can be. Such a return is shown in FIG. 2 shown in dashed lines. The gaseous working medium of the primary thermal power process - z. B. Helium (Fig. 1) or combustion gases (Fig. 2 and 3) - is in Gas turbines 2 relaxed The relaxed working fluid is released to the outside in an open circuit (Fig.2) or in the closed (Fig. 1) or partially closed (F i g. 3) circulation circulated by fan 3 and on the upper pressure stage of the thermal power process compressed - in the circuit according to FIG. 3 for regulating the inlet temperature into the gas turbine 2. The combustion chambers 1 in Fig.2 and 3 is through Blower 4 fresh air supplied The waste heat from this first thermal power process is used in the fuel conversion process 6 indirectly via heat exchanger surfaces (F i g. 1 and 2) or directly by adding Combustion gases (Fig. 3) supplied. Combinations of these sub-processes are possible.
Dem Reaktionsapparat der Brennstoffumwandlung 6 und den Brennkammern 1 (in Fig.2 und 3) wird bei 5 unter Druck Brennstoff zugeführt Der bei der Brennstoffumwandlung entstehende Koks wird bei 7 abgezogen und kann in die Brennkammer rückgeführt werden (F i g. 2). Der Ascheabzug aus den Brennkammern und Einrichtungen zur Reinigung der Reaktionsgase von Reststaub — z. B. Heißgas-EIektrofilter — sind nicht dargestellt. Die aus dem Reaktionsapparat 6 mit einem Druck von mindestens 10 bar und einer Temperatur von z.B. 450 ... 550°C austretenden gasförmigen Reaktionsprodukte werden in Spezialturbinen 9 entspannt, in deren äußeren Umlenkbereichen der überwiegend radial durchströmten Schaufeln die auskondensierenden Bestandteile 10 nach Siedebereichen getrennt selektiv ausgeschieden werden. Die Entspannung kann bis auf Vakuum, pui Atmosphärendrtick oder auf einen Gegendruck durchgeführt werden, der zur Fortleitung der gasförmig verbleibenden Reaktionsprodukte 13 ausreicht Durch Druckerhöhung 11 (in F i g. 2 dargestellt) und Rückführung von Teilströmen der verflüssigten Produkte in den Entspannungsprozeß kann eine fraktionierte Destillation maschinell durchgeführt und dadurch ihr Reinheitsgrad gesteigert werden. Es ist ferner möglich, dem Reaktionsverlauf weitere Fremdstoffe 8 — z. B. WasserstoffFuel is fed under pressure to the reaction apparatus of the fuel conversion 6 and the combustion chambers 1 (in FIGS. 2 and 3) at 5. The coke produced during the fuel conversion is withdrawn at 7 and can be returned to the combustion chamber (FIG. 2). The ash extraction from the combustion chambers and devices for cleaning the reaction gases from residual dust - z. B. hot gas electric filter - are not shown. The gaseous reaction products emerging from the reaction apparatus 6 at a pressure of at least 10 bar and a temperature of, for example, 450 ... 550 ° C are expanded in special turbines 9, in their outer deflection areas of the blades, which are predominantly flowed through radially, the condensing components 10 are selectively separated according to boiling areas be eliminated. The expansion can be carried out down to a vacuum, pui atmospheric pressure or a counter pressure which is sufficient to carry on the gaseous remaining reaction products 13 Distillation can be carried out by machine, thereby increasing its degree of purity. It is also possible to add other foreign substances 8 to the course of the reaction - e.g. B. hydrogen
