3D Combustion Monitoring Based Intelligent Combustion Optimization Control
By adopting advanced wall temperature and gas monitoring and analysis technologies, the data characterizing the actual combustion process of the boiler is modeled, making visible of the three dimensions of combustion safety, environmental and economy.Build detailed models for the assessment of boiler coking, NOx control emissions and boiler economy. Through process big data analysis and in combination with the experience database of combustion optimization experts, form a closed-loop optimizationcontrol model that organically combines predictive optimization and historical optimization. Based on the furnace type and the size and capacity of the furnace chamber, scientifically select the monitoring schemes for the temperature field and gas field,effectively integrate the process correlation of combustion DCS parameters, and form different models.

Key technologies

Design sub-monitoring units for the wall temperature fields of the main combustion zone, the reduction zone and the burnout zone to form an effective three-dimensional monitoring model. By applying advanced servers, real-time operations are conducted on the associated parameters of the combustion process and the three-dimensional monitoring data. Combined with the working condition optimization model for verification, the historical optimization model is completed. According to the characteristics of the boiler burner, combined with the thermodynamic calculation book and the actual consumption difference data, five typical prediction models for "combustion state diagnosis and intelligent optimization" are constructed. "CombineAGCCharacteristics and the inertia of the boiler unit, preset the lead or delay amount of historical optimization and predictive optimization, confirm their factors through debugging, and form a closed-loop control of recheck optimization.
