Premixed burner with profiled air mass stream, gas turbine and process for burning fuel in air

摘要

The invention relates to a premix burner for burning fuel with air to combustion gas, in particular within a combustion turbine. Profiling means are provided for profiling the mass stream of the combustion air in a direction radial to an annular shaped air channel in order to generate a radial varying fuel/air mixture that stabilises the combustion. Accordingly, the invention also relates to a gas turbine and a process for burning fuel in air.
