Abstract
A method to adjust a boiler having a flue gas duct including: sensing flue gas emissions in the gas duct with a plurality of emission sensors arranged in an array; generating a multidimensional graphical depiction of the flue gas emissions by plotting sensor data captured from the emission sensor; adjusting the boiler to modify the distribution of flue gases in the gas duct; generating a subsequent multidimensional graphical depiction of the flue gas emissions by plotting sensor data captured subsequent to the boiler adjustment, and repeating these steps until the graphical depiction displays an acceptable plot of flue gas emissions.

A method to adjust a boiler having a flue gas duct comprising:
- a. sensing flue gas emissions in the gas duct with a plurality of emission sensors arranged in an array;
- b. generating a multidimensional graphical depiction of the flue gas emissions by plotting sensor data captured from the emission sensor;
- c. adjusting the boiler to modify the distribution of flue gases in the gas duct;
- d. generating a subsequent multidimensional graphical depiction of the flue gas emissions by plotting sensor data captured subsequent to the boiler adjustment, and
- e. repeating steps (c) and (d) until the graphical depiction displays an acceptable plot of flue gas emissions.
A method to adjust a boiler having a flue gas duct comprising:
- a. sensing the combustor condition using a sensor array in a gas path of the combustor;
- b. generating data from the sensor array representative of the combustor condition at a plurality of positions in the gas path;
- c. transmitting the generated data to a computer system proximate to a control interface for the combustor;
- d. generating a graphical representation of the showing combustion product conditions in the gas path;
- e. displaying the graphical representation on the computer system;
- f. adjusting combustion controls at the control interface to change the combustor conditions;
- g. repeating steps (a) to (f) to acquire a sequence of graphical depictions of the combustion product conditions over a period of time, and
- h. evaluating each sequential graphical depiction until an acceptable depiction of flue gas emissions is achieved.
A system for adjusting a combustor for a boiler based on a presentation of a changing combustor condition comprising:
- a sensor grid located in the combustion, said grid sensing the combustor condition in real time using a sensor array in a gas path of the combustor and generating data representative of the combustor condition at a plurality of positions in the gas path;
- a network for communicating electronic data;
- a computer system coupled to the network and further comprising a controller and a display, wherein said controller receives the generated data and generates a graphical representation of the real time showing combustor conditions in the gas path, and said graphical representation is presented on said display, and
- a combustor controller including a user interface to receive manual control inputs and an output of combustor control signals generated by the controller, wherein the combustor control signals adjust the combustor.
