Abstract

The station has a gas turbine (1) with exhaust gas that is utilized to save combustion of a considerable part of coal to be gasified. Carbon-di-oxide from the exhaust gas is converted from into carbon monoxide in a gasification generator (4). Carbon-di-oxide portion in the gas reduces to carbon monoxide within a gasification reactor during rising after a reaction equation. Optimally fitting quantity of water vapor is injected into the generator. Additional valuable gas for the drive of the turbine is developed after the reaction equation.

Description

Das Neuartige vorliegender Erfindung liegt in der Weiterentwicklung eines von der KFA-Jülich erfundenen Systems der allothermen Kohlevergasung mit nuklearer Wärme.The Novel present invention lies in the further development one invented by the KFA-Jülich Systems of allothermal coal gasification with nuclear heat.

Dieses System ist im Vergleich zur IGCC-Technik und zu allen anderen Kohlevergasungstechniken deshalb effizienter, weil die Verbrennung eines Teils der zu vergasenden Kohle unterbleibt, denn die nukleare Wärme bringt diese Vergasungsenergie auf. Dadurch werden bis zu 40% der im traditionellen Verfahren erforderlichen Kohle eingespart und die entsprechenden Emissionen CO2, SO2, NOx u. a. Schadstoffe vermieden.This System is compared to the IGCC technique and to all other coal gasification techniques therefore more efficient, because the combustion of part of the gasified Coal is omitted, because the nuclear heat brings this gasification energy on. As a result, up to 40% of those required in the traditional process Saved coal and the corresponding emissions CO2, SO2, NOx u. a. Pollutants avoided.

Es wird mit einem Gesamt-Wirkungsgrad von 60% gerechnet im Vergleich zu 40–55% der traditionellen Verfahren inklusive der IGCC-Technik. (s. u. a. BINE-Info 9/06).It is compared with a total efficiency of 60% to 40-55% traditional methods including the IGCC technique. (see below) a. BINE-Info 9/06).

Das Weiterführende und Neuartige vorliegender Erfindung ist – statt nukleare Wärme zur Kohlevergasung – die Abgase einer Gasturbine dafür zu nutzen.The More and Novel present invention is - instead of nuclear heat to Coal gasification - the Exhaust gases of a gas turbine for it to use.

Das hat den besonderen Vorteil, dass CO2 aus dem Abgas der Gasturbine im Vergasungsgenerator in CO umgewandelt wird und damit eine entscheidende CO2-Emissionseinsparung erreicht wird, was im Folgenden erklärt wird:
Das Abgas der Gasturbine beinhaltet zu einem höheren Anteil CO2 und zu einem geringeren Anteil O2 im Vergleich zu Luft, und dieser CO2-Anteil reduziert sich beim Aufsteigen innerhalb des Vergasungsreaktor zu Kohlenmonoxyd nach der Reaktionsgleichung: CO2 + C = 2CO.This has the special advantage that CO2 from the exhaust gas of the gas turbine in the gasification generator is converted into CO and thus a decisive CO2 emission saving is achieved, which is explained below:
The exhaust gas of the gas turbine contains a higher proportion of CO2 and to a lesser extent O2 compared to air, and this CO2 content is reduced during the ascent within the gasification reactor to carbon monoxide according to the reaction equation: CO2 + C = 2CO.

Um in diesem Kohlevergasungsprozess noch mehr Gas zu erzeugen, wird eine optimal passende Menge an Wasserdampf direkt über dem Rost eingeblasen. Nach der Reaktionsgleichung: C + H20 = CO + H2 entsteht wertvolles Gas für den Antrieb der Gasturbine.Around will produce even more gas in this coal gasification process an optimally fitting amount of water vapor directly above the Rust injected. According to the reaction equation: C + H20 = CO + H2 creates valuable gas for the drive of the gas turbine.

Zur Kohlevergasung sollte Steinkohlen-/Braunkohlenkoks oder Koks von sonnengetrockneter Biomasse (auch Kuhmist) verwendet werden, da bei der Verkokung obiger Ausgangsstoffe ein Gutteil davon schon vergast, beziehungsweise aus der dabei notwendigen Teerabscheidung flüssiger Kraftstoff schon gewonnen wurde.to Coal gasification should be coal / lignite coke or coke from sun-dried biomass (also cow dung) can be used, since in the coking of the above starting materials a good part of it already gasified, or from the necessary tar separation liquid Fuel has already been won.

Der Gesamtwirkungsgrad der Umwandlung würde dann höher als 60% (siehe oben) liegen.Of the Total conversion efficiency would then be higher than 60% (see above).

Ein Ausführungsbeispiel vorliegender Erfindung ist in der Zeichnung 1 dargestellt und wird im Folgenden beschrieben:One embodiment The present invention is shown in the drawing 1 and is described below:
