摘要:
The present invention relates to methods and systems for controlling a combustion reaction and the products thereof. One embodiment includes a combustion control system having an oxygenation stream substantially comprising oxygen and CO2 and having an oxygen to CO2 ratio, then mixing the oxygenation stream with a combustion fuel stream and combusting in a combustor to generate a combustion products stream having a temperature and a composition detected by a temperature sensor and an oxygen analyzer, respectively, the data from which are used to control the flow and composition of the oxygenation and combustion fuel streams. The system may also include a gas turbine with an expander and having a load and a load controller in a feedback arrangement.

The present invention relates to methods and systems for controlling a combustion reaction and the products thereof. One embodiment includes a combustion control system having an oxygen supply stream and a high concentration carbon dioxide stream, mixing the streams to form an oxygenation stream substantially comprising oxygen and CO2 and having an oxygen to CO2 ratio, then mixing the oxygenation stream with a combustion fuel stream and combusting in a combustor to generate a combustion products stream having a temperature detected by a temperature sensor, the data from which is used to control the flow a carbon dioxide diluent stream to produce a desired temperature of combustion. The system may also include a control system configured to regulate the flow of the oxygen supply stream based on the flow rate and composition of the combustion fuel stream. The system may also include a gas turbine with an expander and having a load and a load controller in a feedback arrangement. Other embodiments include a hydrocarbon analyzer and multiple fuel streams that may be combined to form the combustion fuel stream.

Methods and systems for oxyfuel based low emission power generation in hydrocarbon recovery processes are provided. One system includes a plenum and is configured to encourage post-combustor conversion of gaseous components such that a desired chemical state is achieved. Another system includes a steam reformer for reforming a control fuel stream to generate a reformed control fuel stream characterized by an increase in hydrogen, as compared to the control fuel stream.
