Based on the combustion theory and numerical simulation of boiler combustion at Southeast University, and using the combustion control logic of Keyuan Company as a means, the intelligent combustion optimization system for coal powder boilers can provide real-time guidance for the safe, stable, and economical long-term operation of power plant boilers. Starting from the two basic elements of controlling combustion (fuel and air), the Keyuan Intelligent Combustion Optimization System has independently developed an online monitoring system for air and powder, a coal powder concentration balance adjustment system, and a secondary air soft measurement system for each layer, providing reliable real-time measurement data for the intelligent combustion optimization system. The combustion numerical simulation of Southeast University provides a numerical evaluation standard for determining the combustion quality of specific boilers and a reliable optimization standard for intelligent combustion optimization systems.
