Publication number: 20170115007Abstract: The invention concerns a method of controlling the quantity of solid particles emitted by a combustion turbine (1), during the combustion of a liquid fuel, by injecting a combustion catalyst suitable for reducing the quantity of solid particles generated during combustion. This method comprises the following steps: Measuring the quantity of particles (Qsuies) emitted during combustion; Injecting the combustion catalyst into the combustion turbine (1) when the quantity of particles measured is higher than a maximum threshold value; and Stopping the injection of the catalyst when the measured quantity of particles is lower than a minimum target value.Type: ApplicationFiled: September 27, 2016Publication date: April 27, 2017Inventors: Maher ABOUJAIB, Matthieu VIERLING, Ezio PENA, Denis MARTIN
