Abstract
A combustor includes a first premixture supply device provided in a central portion of a combustion chamber disposed generally concentric with a combustion cylinder, and a second premixture supply means provided adjacent to an outer periphery of the first premixture supply device. The first premixture supply device is operable when the combustor is under a high load, and the second premixture supply device is operable when the combustor is under a low load. A method of operating a combustor is also proposed wherein the combustor comprises a combustion cylinder having a combustion chamber therein and a premixture supply device provided on one side of the combustion cylinder for supplying a combustible mixture to the combustion chamber. The premixture supply device comprising at least two inner and outer premixture supply devices. The outer premixture supply device is operable in a low-load range of the combustor while the inner and outer premixture supply devices are operable in a high-load range of the combustor at above a predetermined load. The first and second premixture supply devices include first and second burners, respectively. The first and second burners are operated in such a manner that the ratio of the load borne by the first burner to the load borne by the second burner is 1:1 in the high-load range.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
