Optimization and Adjustment Research on 300 MW Coal-fired Boiler Combustion
The 300 MW coal-fired boiler in a power plant is taken as the research object to analyze the impact of parameters such as dynamic separator frequency,coal mill output and other factors on coal powder fineness.The optimization and adjustment tests are conducted on the boiler combustion system,specifically focusing on adjusting parameters such as boiler operating oxygen con-tent,dynamic separator frequency,exhaust air damper opening degree and over-fire air damper opening degree.The boiler ther-mal efficiency and nitrogen oxide content are calculated under each operation condition.Based on the test results,the most ratio-nal operation control parameters are determined,and the precautions during operation are proposed.
