Research and Application of Optimization Technology for Boiler Primary Air Flow Field
This study aims to address the issues of large concentration deviation in pulverized coal pipes at the outlet of a medium-speed coal mill and inaccurate measurement of primary air inlet flow in a power plant.Through the optimization and adjustment of cold and hot primary air ducts as well as air flow measurement devices,a significant improvement in the uniformity and stability of the primary air flow field has been achieved.Meanwhile,an adaptive control system for primary air flow is introduced,which ensures the stability of air flow through real-time monitoring and adjustment.The effectiveness of the optimization scheme is verified through experimental evaluation,and the results show that the performance of the primary air flow field has been improved,enhancing the automatic adjustment quality and measurement accuracy of the system.
