Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional datadriven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively, based on the analysis of primary air system ...

In the Topping Cycle, coal is partially gasified in an airblown spouted bed gasifier operating at elevated pressure (Figure 1).Sorbent is also injected into the gasifier to retain sulphur which would otherwise be released in the gas. The fuel gas from the gasifier is passed to a filtration unit, to remove solids and then burnt in the combustor of a gas turbine to generate power.
