Combustion Vision Analysis Based Automatic Control of Large Scale MSW Incinerator
An automatic control strategy of waste incineration grate based on machine vision and intelligent control is proposed in this paper.The strategy is based on the control logic of manual operation,through the machine vision method to obtain flame information in the image,combined with the model predictive control(MPC)and fuzzy control(FC)to implement automatic control of the air distribution system and grate system.The results show that the accuracy rate of flame information extraction by this machine vision method is higher than 80%.This control strategy can effectively reduce the fluctuation of the key parameters in the furnace,including main steam flow,furnace temperature,boiler outlet oxygen,etc.The average deviation of the three compared with the set value is reduced by 92.8%,27.2%and 62.2%,and the standard deviation is also reduced by 42.8%,26.5%and 21.8%.In addition,the average CO emission of the boiler is decreased by 23.9%.This control strategy has good practical significance and provides a reference for the automatic transformation of large-scale waste incinerators in the future.
