Abstract:
A process for combusting a low heating value fuel gas to drive a gas turbine comprising:a) dividing a low heating value fuel gas feed into a burner portion and a combustion chamber portion;b) conveying said combustion chamber portion and a combustion air into a mixing zone to form an air/fuel mixture;c) conveying said burner portion into a flame zone through a burner nozzle while conveying a first portion of said air/fuel mixture into said flame zone through a burner port;d) contacting said burner portion and said first portion of said air/fuel mixture in said flame zone to combust said burner portion and said first portion and produce flame zone products;e) conveying said flame zone products into an oxidation zone downstream of said flame zone while conveying a second portion of said air/fuel mixture into said oxidation zone and combusting said second portion in said oxidation zone in the presence of said flame zone products to produce combustion products; andf) conveying said combustion products into a gas turbine and driving said gas turbine with said combustion products.
