The combustion optimizing system of boilers can enhance combustion efficiency

reduce coal consumption of power generation

and decrease emission of gaseous NOx.The operation parameters and features of the combustion optimizing system in Changxing Power Generation Co Ltd have been presented.It is believed that the double biased control means of the said system

as well as the flexibility of putting the on-line monitoring system for carbon conten in fly ash into operation and taking it off

can make the operation of combustion optimizing system to be even more agile and even more effective

and ensure not producing bad effect onto the original system.At the same time

some problems existing in the process of application have been pointed out

such as it is easily to cause over-temperature in the boiler

to produce coal plugging in the coal pulverizer

as well as need to perfect automatic control of the oxygen content and of the draf air etc..
