Abstract:In order to meet the requirement of environmental emission standards,reduce desulfurization
cost of smelting units,and aim at the problem of sintering flue gas pollution in smelting enterprises,
automatic ammonia injection and combustion heating in traditional limestone+ gypsum wet desulfurization
process was designed.The model predictive control technology was used to model the desulfurization
reaction link and combustion and heating process of hot blast stove,predict and control SO2concentration
at flue gas outlet and reactor temperature,and reduce the disturbance of interference factors to the lowest
level.The actual operation results show that application of the
