There are shortages of the currently used methods for measuring and adjusting coal air flow field in a boiler furnace. A tracer-based, image visualizing system is being proposed to provide realtime display, analysis and adjustment of coal air flow. The paper discusses the hardware configuration and function of the proposed system including geometric parameters characterizing the air flow at different location in a boiler furnace. Then, a C++ based software and method, which are used to calculate air flow images’ geometric parameters such as the boundary line, centerline and deflected angle of an air jet from a burner nozzle are introduced. Finally, methods for adjusting the cold air flow field in furnaces with the visualizing system and coupled equations used to optimize the air flow rate of each burner nozzle of a boiler are described.
