Granted: 2021-03-22
Abstract: FIELD: energy sector.SUBSTANCE: low-emission combustion chamber (CC) of a gas turbine running on gaseous fuel, consisting of the duty (DZ) and main (MZ) fuel combustion zones. Each of the combustion zones has its own fuel manifold and tangential swirler in the front part. For better mixing of the air-fuel mixture, gaseous fuel is supplied through a series of holes located between the swirler blades. Air is supplied to the combustion chamber through two swirlers and two belts of holes. The combustion process in the DZ begins immediately after the swirler, which is a flame stabilizer. A series of holes dilutes the combustion products to αDZ≈1.6…1.8. Further, the hot combustion products ignite the main fuel mixed with air at αMZ≈0,7…2,0. After that, intensive combustion of the fuel-air mixture takes place up to a number of radial holes of the MZ.EFFECT: invention reduces the emission of harmful substances during the operation of the CC in boundary conditions close to the lean flameout boundaries, by increasing the efficiency of mixing fuel and air and optimally dividing the combustion zone into two zones.1 cl, 1 dwg
