Research and Application of Carbon Monoxide Measurement in Coal Fired Boiler
When oxygen deficiency occurs in coal-fired boilers,there is a lack of real-time,accurate,and reliable instruments behind the boiler to detect this condition and guide combustion adjustments,resulting in a decrease in boiler efficiency.To improve the combustion efficiency of boilers,a boiler CO online detection scheme is designed by comparing and studying several commonly used advanced detection technologies.Research has shown that setting up a CO analyzer in the flue behind the furnace,using electrochemical or TDLAS technology,is more suitable for online CO measurement and combustion optimization control in power plant boilers.This scheme can accurately detect CO emissions from boiler flue gas in real time,which is used for combustion optimization control and improves the economic efficiency of boiler operation.
