Abstract
The method involves treating the residual combustible gases in a pressure vessel, so that thermal value of the gas mixture, measured as the Wobbe Number, is maintained within +/-10% of the gas turbine manufacturer's specification, and the rate of variation of the Wobbe Number is kept below 1% per second. From a gas-holder, the residual gases are delivered, by a compressor, to a pressure vessel where the pressure is held at the required inlet for the gas turbine. The residual gas is dosed with a fuel gas of a high thermal value, e.g. natural gas. The volume of the pressure vessel is sufficiently large to enable the value and rate of change of the Wobbe Number to be kept within the above limits. Inert gas, e.g. nitrogen or carbon dioxide, can be fed to the pressure vessel to maintain the quality when residual gas availability is low.
Description
Die Eigenschaften von gasförmigen Brennstoffen dürfen für die Verbrennung im Brennkammersystem einer Gasturbine nur in engen Grenzen schwanken. Wesentlich sind die Wobbe-Zahl (Schwankung < ± 10%) und die zeitliche Än derung der Wobbe-Zahl (< 1%/sec). Sollen gasförmige Reststoffe, die aus einer oder mehreren Quellen stammen und in ihrer Zusammensetzung und ihrem Massenstrom variieren können, im Brennkammersystem einer Gasturbine verbrannt werden, müssen sie zuvor konditioniert werden, um die eingangs ge nannten Spezifikationen zu erfüllen. Hierfür wird folgendes Verfahren vorge schlagen (Abb. 1).The properties of gaseous fuels for combustion in the combustion chamber system of a gas turbine may only fluctuate within narrow limits. The Wobbe number (fluctuation <± 10%) and the temporal change in the Wobbe number (<1% / sec) are essential. If gaseous residues, which originate from one or more sources and can vary in their composition and mass flow, are burned in the combustion chamber system of a gas turbine, they must be conditioned beforehand in order to meet the specifications mentioned at the outset. The following procedure is suggested for this ( Fig. 1).
In einer Sammelleitung werden die zur Verbrennung vorgesehenen Restgas ströme gesammelt und der Saugseite eines Verdichters zugeführt. Der verdich tete Restgasstrom wird einem Druckbehälter zugeleitet. Dessen Druck soll mindestens dem erforderlichen Vordruck des Brennkammersystems der Gas turbine entsprechen. Aus dem Druckbehälter wird das Brennkammersystem ge speist. Um die Wobbe-Zahl dieses Gasstroms von dem Restgasstrom zu ent koppeln, wird bei Bedarf ein heizwertreiches Brenngas (z. B. Erdgas) dem Druck behälter zugeführt und so die Konstanz der Wobbe-Zahl gewährleistet. Das Volumen des Druckbehälters bestimmt sich aus der Forderung, daß auch bei der im Realfall größtmöglichen zeitlichen Änderung der Zusammensetzung des Restgasstroms, die vom Gasturbinenhersteller geforderte maximal zulässige zeitliche Änderung der Wobbe-Zahl des Gasturbinenbrennstoffs unterschritten wird. Außerdem muß die Forderung nach vollkommener Durchmischung aller Gasströme gewährleistet sein. Als größtmögliche zeitliche Änderung wird der schlagartige Ausfall des größten Restgaslieferanten angesehen.The residual gas intended for combustion is stored in a manifold flows collected and fed to the suction side of a compressor. The condense Residual gas flow is fed to a pressure vessel. Whose pressure should at least the required pre-pressure of the gas combustion chamber system turbine correspond. The combustion chamber system is ge from the pressure vessel feeds. To remove the Wobbe number of this gas stream from the residual gas stream couple, if necessary a high-calorific fuel gas (e.g. natural gas) becomes the pressure container supplied and thus the constancy of the Wobbe number guaranteed. The Volume of the pressure vessel is determined from the requirement that also at the greatest possible change in the composition of the Residual gas flow, the maximum permitted by the gas turbine manufacturer the change in the Wobbe number of the gas turbine fuel fell below becomes. In addition, the demand for complete mixing of all Gas flows can be guaranteed. The greatest possible change over time is the Sudden failure of the largest residual gas supplier viewed.
Dem Druckbehälter kann darüber hinaus Inertgas wie N2 oder CO2 zugesetzt werden, um einen gewünschten Massenstrom unabhängig vom Massenstrom der Restgase einstellen zu können.Inert gas such as N2 or CO2 can also be added to the pressure vessel be a desired mass flow regardless of the mass flow to be able to adjust the residual gases.
