| 摘要 |
<p>The invention refers to a plant with a fuel system comprising a gas separation system (16), for separating at least a first fuel fraction (14) with high hydrocarbons, which has a higher concentration of high hydrocarbons than an incoming fuel gas (5). Thereby a second fuel fraction (20) with a reduced concentration of high hydrocarbons is provided. A fuel gas supply line for incoming fuel (5) and/or a fuel line for the second fuel fraction (20) leads to the combustor (4, 15) of the gas turbine for feeding fuel gas (5, 20) into the combustor (4, 15). Further a fuel line for feeding the first fuel fraction (14) leads to the at least one combustor (4, 15) to control the combustion behaviour by controlled addition of the first fuel fraction (14) into the combustor (4, 15). The disclosure further refers to the operation of such a plant by controlling the combustion behaviour with the controlled addition of a high hydrocarbon fuel.</p> |
