Modeling of Texaco Gasifier Soft Measurement and Its Engineering Actualization

In light of the technical flow of coal gasification and demand of Texaco gasifier temperature soft measurement, many questions about modeling, such as selections of auxihary variable, collection and disposal of fields data, are discussed. And the modeling of gasifier soft measurement is composed by two methods, which are fuzzy neural network and radial basic function network. Without increase of equipment, the technical operation and management level can be improved, through factory integrated information and advanced supervisal technology. The application results show that the modeling method is excellent and the precision is high. The disadvantage of produce process caused by the thermocouple burned out is eliminated.
