Abstract
The present techniques are directed to systems and a method for extracting a high pressure gas from a power plant. A method includes providing a fuel to a burner, and providing an oxidant to the burner, wherein an oxidant flow rate is adjusted to provide a substantially stoichiometric ratio of the oxidant to the fuel. The fuel and the oxidant are combusted in the burner to produce an exhaust gas. At least a portion of the exhaust gas is extracted downstream of the burner to form a product gas.
Claims23
A power plant, comprising:
- an oxidant system configured to provide a high pressure oxidant stream;
- a fuel system comprising a high pressure fuel stream;
- a burner configured to combust the high pressure oxidant stream with the high pressure fuel stream to produce a high pressure exhaust gas;
- a product gas system configured to extract at least a portion of the high pressure exhaust gas to form a product gas;
- and
- a recycle system configured to return a portion of the high pressure exhaust gas to the burner as a diluent.
3 more elements
A gas turbine system, comprising:
- an oxidant system configured to provide a high pressure oxidant stream;
- a fuel system configured to provide a high pressure fuel stream;
- a combustor configured to combust the high pressure oxidant stream with the high pressure fuel stream to produce a high pressure exhaust gas;
- an expander turbine configured to be driven by the high pressure exhaust gas, generating mechanical energy and a low pressure exhaust stream;
- and
- a product gas system disposed between the combustor and the expander turbine, wherein the product gas system is configured to extract at least a portion of the high pressure exhaust gas to form a product gas.
