Abstract
A gasification system includes a gasifier configured to gasify a feedstock and an oxidant to generate a producer gas, a steam generator configured to supply steam to the gasifier, and a combustion system configured to supply an exhaust gas to the steam generator to produce the steam. The system also includes an exhaust gas injection system located upstream of the gasifier and fluidly coupled to the gasifier. The exhaust gas injection system is configured to supply a portion of the exhaust gas from the combustion system to the gasifier.
Claims21
A gasification system, comprising:
- a gasifier configured to gasify a feedstock and an oxidant to generate a producer gas;
- a steam generator configured to supply steam to the gasifier;
- a combustion system configured to supply an exhaust gas to the steam generator to produce the steam;
- and
- an exhaust gas injection system located upstream of the gasifier and fluidly coupled to the gasifier, wherein the exhaust gas injection system is configured to supply a portion of the exhaust gas from the combustion system to the gasifier.
A method, comprising:
- providing a fuel source and a gasifying agent to a gasifier;
- supplying a steam generator fluidly coupled to the gasifier with an exhaust gas from a combustion system to produce a steam;
- supplying the gasifier with a portion of the exhaust gas, wherein the portion of the exhaust gas flows through an exhaust gas injection system located upstream of the gasifier and fluidly coupled to the gasifier;
- and
- gasifying a mixture of the fuel source, the gasifying agent, the steam, and the portion of the exhaust gas in the gasifier to generate a producer gas.
A system, comprising:
- instructions disposed on a non-transitory, machine readable medium, wherein the instructions are configured to:
- supply an exhaust gas injection system located upstream of a gasifier with an exhaust gas from a combustion system, wherein the exhaust gas injection system is fluidly coupled to the gasifier;
- supply a steam generator fluidly coupled to the gasifier with the exhaust gas to produce steam;
- and
- gasify a mixture of a feedstock, the steam, and the exhaust gas in the gasifier to generate a producer gas.
