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.
