Abstract
According to one aspect, a method of controlling a multi-combustor catalytic combustion system is provided for determining a characteristic of a fuel-air mixture downstream of a preburner associated with a catalytic combustor and adjusting the fuel flow to the preburner based on the characteristic. The characteristic may include, for example, a measurement of the preburner or catalyst outlet temperature or a determination of the position of the homogeneous combustion wave in the burnout zone of the combustor.
Claims32
A method of controlling a multi-combustor catalytic combustion system comprising the acts of:
- determining a temperature downstream of a preburner associated with a catalytic combustor in a multi-combustor system, wherein the preburner includes two or more fuel stages and wherein fuel flow to the two or more fuel stages is determined based upon a fixed fuel split schedule during an ignition sequence;
- and
- adjusting the fuel flow to the preburner based on the temperature.
A method of controlling a multi-combustor catalytic combustion system comprising the acts of:
- varying at least one of a fuel flow and an airflow to a plurality of combustors;
- and
- controlling the location of a homogeneous combustion wave in each of the plurality of catalytic combustors.
A method of controlling a multi-combustor catalytic combustion system comprising the acts of:
- determining a first characteristic of operation for at least one combustor in a multi-combustor system;
- determining a second characteristic of operation for the multi-combustor system;
- and
- controlling the system based upon feedback from the first characteristic and the second characteristic, wherein the first characteristic includes the position of a homogenous combustion wave.
A method of controlling a multi-combustor catalytic combustion system comprising the acts of:
- determining a first characteristic of operation for at least one combustor in a multi- combustor system;
- determining a second characteristic of operation for the multi-combustor system;
- and controlling the system based upon feedback from the first characteristic and the second characteristic, wherein the second characteristic includes a measure of CO emissions.
