Abstract: A system for reducing fouling and improving efficiency in a coal-fired power plant that may include: 1) an analyzer grid, the analyzer grid including a plurality of sensors that measure gas characteristics through an approximate cross section of a flow through a boiler of the coal-fired power plant; 2) a plurality of air injectors with enhanced controllability; 3) means for analyzing the measurements of the gas characteristics; and 4) means for controlling the air injectors with enhanced controllability. The analysis of the measurements of the gas characteristics may include analyzing the measurements to determine zones of non-homogeneous flow.

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.

Abstract: A method for displaying a changing combustor condition including: sensing the combustor condition in real time using a sensor array in a gas path of the combustor; generating data from the sensor array representative of the combustor condition at a plurality of positions in the gas path; transmitting the generated data to a computer system proximate to a controller for the combustor; generating a graphical representation of the real time showing combustor conditions in the gas path, and displaying the graphical representation in real time on the computer system.
