Abstract
A combustion system includes a combustion chamber for generating energy. The system includes a first inlet for supplying an oxidant into the chamber and a second inlet for supplying a fuel into the chamber. The system also includes a third inlet in fluid communication with the first inlet for supplying oxygen into the chamber. The system further includes a fourth inlet for supplying hydrogen into the chamber. A circulation line is used to deliver a flue gas from the chamber to the first inlet.
Claims20
A combustion system, comprising:
- a combustion chamber;
- a first inlet for supplying an oxidant into the chamber;
- a second inlet for supplying a fuel into the chamber;
- a third inlet in fluid communication with the first inlet for supplying oxygen into the chamber;
- a fourth inlet for supplying hydrogen into the chamber;
- and
- a circulation line for delivering a flue gas from the chamber to the first inlet.
A method operating a combustion system having a chamber, comprising:
- supplying air via a first inlet into the chamber;
- supplying a carbon containing fuel via a second inlet for combustion with the air;
- supplying oxygen via a third inlet while reducing the air being supplied;
- circulating a flue gas into the chamber while reducing the supply of air;
- and
- supplying the carbon containing fuel via a plurality of fourth inlets and stopping flow of the carbon containing fuel from the second inlet;
- and
- supplying hydrogen via a plurality of fifth inlets while reducing flow of the carbon containing fuel from the plurality of fourth inlets.
A method operating a combustion system having a chamber, comprising:
- supplying a flue gas via a first gas line into the chamber;
- supplying oxygen into the first gas line at a location upstream from the chamber;
- supplying a carbon containing fuel via a first inlet of a second gas line for combustion with the oxygen;
- supplying the carbon containing fuel via a plurality of second inlets of the second gas line and stopping flow through the first inlet;
- and
- supplying hydrogen via a plurality of third inlets while reducing flow of the carbon containing fuel from the plurality of second inlets.
