Combustion system with low pollutant emission for gas turbines

摘要

A combustion system with low pollutant emission, of the pre-mixing type for gas turbines, in which the combustion air passes from the interspace to the pre-mixing chamber (2) via apertures (25) in this latter, their degree of opening being varied, in accordance with the fuel quantity used, by corresponding apertures (27) in a rotatable drum (28), and in which a series of small holes (34) fed with additional fuel is provided in the interspace. Further flame stabilization expedients and differential cooling of the combustion chamber are also provided.
