CPC F02C 9/28 (2013.01) [F02C 9/40 (2013.01); F23R 3/36 (2013.01); F05D 2220/32 (2013.01); F05D 2270/0831 (2013.01)] | 9 Claims |
1. A method of controlling a fuel blend for a turbine engine, said method comprising:
supplying a first fuel and a second fuel to a mixer;
mixing, in the mixer, the first and second fuels together to obtain the fuel blend;
receiving, from a fuel blend analyzer downstream from the mixer, a measurement indicative of a composition of the fuel blend;
comparing, by a controller, the fuel blend measurement to an operational model of a combustor;
determining, based on the comparison, predicted combustion conditions in the combustor associated with the fuel blend measurement;
controlling, based on the predicted combustion conditions, at least one of the flow of the first fuel and the flow of the second fuel;
combusting the fuel blend in the combustor;
receiving, from sensors coupled to the combustor, the sensors including a knock sensor and at least one of an optical sensor, a temperature sensor, and a pressure sensor, combustion signals indicative of combustion behavior in the combustor;
comparing, by the controller, the predicted combustion conditions to the combustion signals;
determining, by the controller, whether the predicted combustion conditions match the combustion behavior indicated by the combustion signals; and
updating the operational model if the predicted combustion conditions do not match the indicated combustion behavior.
