摘要
An improved combination (110) of a premixing chamber (112) and a combustion chamber (111), with low emission of pollutants, for gas turbines running on liquid and/or gas fuel, in which the combustion chamber (111) has a truncated conical end (111a) and is surrounded by a cavity (115) for cooling air (120), the cavity (115) carrying combustion air (120a) to the premixing chamber (112), which has at its inlet apertures or ports (126) which can be constricted according to the quantity of fuel used, and at its outlet a circumferential set of burners (134) to create a corresponding set of additional flames; gas fuel supply means (125) fuel and liquid fuel injection devices (119) are provided in the premixing chamber (112), and a set of liquid fuel injectors (140) is present on the end (111a).
