WebThe basic sootblowing–fouling curve could be extracted (similar to Fig. 7, Fig. 10), and an adaptive scaling conducted so as to reduce the impact of load levels. The drawbacks of working with linearized models are that physical interpretation is weakened and addition of further knowledge might be cumbersome. WebFouling is often divided into external and internal fouling, depending on where the foulant is deposited. The type of feedwater determines the severity of fouling. Generally speaking, the relative proportion of sources of fouling is: (1) organic fouling – 50%, (2) colloidal fouling – 30% and (3) mineral scaling – 20%.
