Abstract: PROBLEM TO BE SOLVED: To prevent a pressure collision in a burner by greatly effectively stabilizing flame in a lean premixing burner compared with conventional pilot flame. SOLUTION: In a method for operating a gas turbo-device, the gas turbo- device comprises a compressor 1, a combustor 5, a turbine 2 and a generator 3. Fuel is mixed with air compressed by the compressor 1 before combustion in a premixer 18 of the combustor 5 and is burned in the combustion room 19. Compressed air supplied via a partial air introduction pipe 15 is mixed with fuel supplied via a partial fuel introduction pipe 16 and is introduced into a reactor 10 coated by a catalyst. Fuel-air mixture is transformed into synthetic gas including hydrogen, carbon monoxide, remaining air and remaining fuel and the synthetic gas is injected into an area in the combustion room 5 where flame is stable.

Abstract: PROBLEM TO BE SOLVED: To stabilize the combustion of premix flame effectively even in any operating process across all load areas. SOLUTION: A part of mixture 16, formed in the end unit of a mixing division, is branched and is mixed into an outside re-circulating area 10. Branched sub flow 9 is mixed completely into high-temperature gas 17 generated by combustion in a combustion chamber and re-circulated to the outside re-circulating area 10, and, thereafter, the outside re-circulating area 10 is brought into contact with the main flow 16 of remaining mixture of air and fuel from the mixing division.

Abstract: In the gas turbine power generation plant, compressed air is fed through a part channel (15) with part of the fuel channel (16), to give an air/fuel mixture feed into a reactor (10) with a catalyst coating. In the reactor (10), the air/fuel mixture is converted into a synthesised gas containing hydrogen, carbon monoxide, residual air and residual fuel. The synthesised gas is injected into the combustion chamber (5) zones where the flames are stabilised. The fuel is natural gas and/or methane

Abstract: The mixture (25) of pilot gas (10) and air (17) for combustion is conveyed to a converter (21) inside the fuel lance (8) at the tip of the burner (2) for ignition and burning. The main burner gas (4) is supplied to the burner via a main gas pipe connected to the burner, and the pilot gas is supplied by a separate inflow pipe via the lance. The current of hot gas is mixed with the colder main current of gas inside the burner. The pilot gas is fed under pressure by a jet pump (22) integrated with the fuel lance. A sufficient quantity of combustion air is supplied from the plenum chamber outside the burner cap (6) into the lance, and pre-mixed with the pilot gas.
