LEVELLING OF TEMPERATURE FIELD IN GAS TURBINES Russian patent published in 2014 - IPC F02C7/22 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in power engineering, particularly in gas transfer plants, self-contained electric power stations and other power plants including gas turbine drive running on natural gas. In compliance with this method fuel is fed to separate burners at critical flow parameters in channels with identical flow sections. Lengthwise profiles of all channels comply with that of any randomised channel, being preferably the first one made at precision defined by fabrication error. Note here that walls of said channels feature equal surface roughness. Note here also that equality of flow rates of fuel fed into inlet of every channel is ensured by adjusting element arranged at channel inlet and composed by, preferably, a chamfer of geometrical sizes that can be varied at tuning of said channel to preset flow rate.

EFFECT: uniform temperature field ahead of gas turbine plant turbine.
