Method of detecting waste supply abnormality, waste supply control method, waste supply abnormality detection device and waste supply control device

摘要

Problem to be solved.A waste supply abnormality detection deviceAt least one of the measurements related to the combustion state of the waste and the operating conditions of the waste incineratorAs a predictive factor for predicting the stagnation of waste supplyAs the explanatory variable, the above described predictive factor for a predetermined period of time from the previous time to the reference timeThe predicted vapor generation rate, which is the amount of steam generation at the prediction time of the future, is the target variable.Multiple regression analysisDecision treePrediction model using random forest and deep learningThe learning part 45 which learns the result value of explanatory variables and object variablesThe data of the explanatory variables are input as the current time to the prediction model to be learned.A prediction part 41a for obtaining the predicted vapor generation quantity andThe difference calculating section 41b calculates the difference of the steam generation quantity by subtracting the predicted steam generation quantity from the steam generation amount in the past time from the prediction time andBased on the difference, there is provided a detecting portion 41c for detecting presence or absence of abnormality in the waste supply.Diagram
