Burn-through point predication method based on analysis of discharged flue gas

The invention provides a burn-through point predication method based on analysis of discharged flue gas. An on-line flue gas analyzer is adopted in the method to analyze the concentration of CO and CO2 in the sintering process in real time, meanwhile, the position data of a burn-through point are monitored according to the concentration of the CO and CO2 obtained by the on-line flue gas analyzer, and the predication of the burn-through point is finally achieved by building a database, pre-processing the data and building a burn-through point predication model. According to the burn-through point predication method, the burn-through point can be accurately predicated, the control accuracy of the sintering production process can be improved, the large hysteresis of sintering production process control is greatly weakened, and therefore the timely and accurate adjustment of the production process is achieved, and accordingly the function of improving system efficiency and process quality is achieved.
