Study on optimization of oxygen content in flue gas at the furnace outlet under operation condition of 200 MW

180 MW

and 160 MW of a 200 MW coal-fired unit in one power plant has been carried out

the affecting regularity of oxygen content in flue gas upon the operation performance of utility boiler being obtained. The results show that the corresponding optimal oxygen content to be 3.6%

3.8%

and 4.5% respectively

these parameters providing reference basis for ecomomic operation of utility boilers.
