Abstract
A gas turbine is provided that includes combustor configured to burn a low-heating-value fuel and further configured to receive steam that is injected into the gas turbine. A method of modifying a gas turbine and for operating a gas turbine are presented.
Claims7
A process for operating a turbine having a combustor with a mixing zone, a flame zone, oxidation zone, and an expansion, the process comprising the steps of:
- dividing a low-heating-value fuel gas feed into a burner portion and a combustion chamber portion;
- conveying said combustion chamber portion and a combustion air into a mixing zone to form an air/fuel mixture;
- 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;
- 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;
- conveying said flame zone products into the oxidation zone downstream of said flame zone while conveying a second portion of said air/fuel mixture into said oxidation zone and reacting said second portion in said oxidation zone in the presence of said flame zone products to produce combustion products;
- introducing superheated steam in the expansion zone where it is mixed with the combustion products;
- conveying said combustion products and steam into a gas turbine expander to drive said gas turbine to rotate a shaft to carry a load.
A process for manufacturing a low-heating-value gas turbine comprising the steps of:
- providing a gas turbine;
- modifying the combustor of said gas turbine to operate on a low heating-value fuel;
- and
- providing a steam injection means for injecting steam downstream of a flame zone of the combustor.
A hydrocarbon conversion process that uses a gas turbine, the process comprises the steps of:
- preparing a synthesis gas;
- converting the synthesis gas to Fischer-Tropsch products and a low-heating-value tail gas;
- delivering the tail gas to the gas turbine;
- using the tail gas in the gas turbine;
- using at least some compressed air from the gas turbine in the step of preparing synthesis gas;
- generating steam;
- and
- injecting the steam into the gas turbine to assist in the production of power.
