COMBUSTOR RE-LIGHT PROCEDURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18337477 titled 'COMBUSTOR RE-LIGHT PROCEDURE
Simplified Explanation: The patent application describes a method for operating a gas turbine engine with a staged combustor, where fuel flow is biased to specific nozzles during a re-light procedure by transferring heat from oil to fuel to lower fuel viscosity.
- The method involves biasing fuel flow to a subset of fuel spray nozzles adjacent to ignitors during a re-light procedure.
- Heat is transferred from oil to fuel before entering the combustor to reduce fuel viscosity to 0.58 mm/s or lower at cruise conditions.
- This innovation aims to improve the efficiency and reliability of gas turbine engines by optimizing fuel delivery during re-light procedures.
Key Features and Innovation: - Biasing fuel flow to specific nozzles during re-light procedures - Transferring heat from oil to fuel to lower viscosity - Enhancing efficiency and reliability of gas turbine engines

Original Abstract Submitted
There is provided a method of operating a gas turbine engine. The gas turbine engine comprises a staged combustor having an arrangement of fuel spray nozzles in which fuel flow is biased to a subset of the nozzles adjacent one or more ignitors during a re-light procedure. The method comprises transferring heat from the oil to the fuel before the fuel enters the combustor so as to lower the fuel viscosity to 0.58 mm/s or lower on entry to the combustor at cruise conditions. Also disclosed is a gas turbine engine.
