Abstract
Burner combustion of a fossil fuel fired boiler is optimized by using information about the combustion of each burner in the one or more groups of burners in the boiler. Controlled changes to certain combustion related manipulate variables selected for each burner are used with the combustion index for that burner to tune the combustion of each of the burners in each of the groups of burners to give a balanced combustion. Global objectives such as minimizing global NOx and CO emissions can also be achieved.
Claims24
A computer program product for optimizing combustion in a fossil fuel fired boiler having one or more burners arranged in a group of burners, said computer program product comprising:
- computer usable program code configured to permit for each of said one or more burners in said group of burners one or more combustion related manipulate variables to be selected for use in tuning the combustion of each of said one or more burners;
- computer usable program code configured to provide a combustion index (CI) for each of said one or more burners;
- and
- computer usable program code configured to use said CI and controlled changes in said one or more selected combustion related manipulate variables to tune the combustion of each of said one or more burners in said group of burners so that each of said one or more burners in said group achieves an associated maximum value of CI.
A system for optimizing fossil fuel fired burner combustion in a boiler, said boiler comprising one or more burners arranged in a group of burners, comprising:
- a computing device having therein program code usable by said computing device, said program code configured to:
- permit for each of said one or more burners in said group of burners one or more combustion related manipulate variables to be selected for use in tuning the combustion of each of said one or more burners;
- provide a combustion index (CI) for each of said one or more burners;
- and
- use said CI and controlled changes in said one or more selected combustion related manipulate variables to tune the combustion of each of said one or more burners in said group of burners so that each of said one or more burners in said group achieves an associated maximum value of CI.
A computer program product for optimizing combustion in a fossil fuel fired boiler having two or more groups of burners, each of said two or more groups of burners having one or more burners, said computer program product comprising:
- computer usable program code configured to permit for each of said one or more burners in said two or more groups of burners one or more combustion related manipulate variables to be selected for use in tuning the combustion of each of said one or more burners in each of said two or more groups of burners;
- computer usable program code configured to provide a CI for each of said one or more burners in each of said two or more groups of burners;
- and
- computer usable program code configured to use said CI and controlled changes in said one or more selected combustion related manipulate variables to tune the combustion of each of said one or more burners in each of said two or more groups of burners so that each of said one or more burners in said two or more groups of burners achieves an associated maximum value of CI.
