GAS TURBINE FUEL PREPARATION AND INTRODUCTION METHOD

摘要

Method of preparing and introducing fuel into the combustors (28) of a gas turbine (20) in which a hydrocarbon containing feed (10), oxygen (36) and steam (35) are introduced into a catalytic partial oxidation reactor (12) at an oxygen to carbon ratio of between about 0.08 and about 0.25 and a water to carbon ratio of between about 0.05 to about 0.5. The hydrocarbon containing feed contains no less than about 15 percent by volume on a dry basis of hydrocarbons with at least two carbon atoms and/or at least about 3 percent by volume of olefins. The feed (10), oxygen (36) and steam (35) are introduced into the reactor (12) at a temperature no greater than 600°C to produce a product stream (14) at a temperature of between about 600 °C and 860°C and that contains less than about 0.5 percent of olefins and less than 10 percent of hydrocarbons with two or more carbon atoms on a dry basis. Product stream (14) can be used as all or a part of the fuel to gas turbine (20).
