Combustion Optimization And On-line Monitoring On The Power Plant Boiler's Burning Condition

In this thesis, the measuring methods of main combustion parameters of coal burning boiler are analyzed and compared on the basis of the conclusion of relative experiences of both here and abroad. And by integrating relative knowledge of the combustion regulation of coal burning boiler, a set of the on-line monitoring system of the combustion condition of boiler is designed and developed , which is used to measure the important parameters of the burning process of boiler exactly, and is suitable to the tangentially fired furnace boiler.On the basis of above, the thesis makes a preliminary discuss on the optimization and regulation of boiler's burning condition. The thesis also analyzes and investigates the main factors contributing to boiler's burning process. And by means of testing, the thesis puts emphasis upon the study of the low-oxygen combustion technique , which can optimize boiler's combustion by adjust the excess air factor. The thesis also makes a study of the combustion optimization of boiler at the part load condition through testing, and draws some useful conclusions.
