# CFB Boiler Synthetic Fault Dataset

1,320 rows of circulating fluidized bed (CFB) boiler SCADA telemetry at 5-second intervals. Contains 600 rows of real steady-state operation followed by 720 rows with a synthetic induced draft fan degradation fault injected using FOPDT dynamics.

Derived from the [Kaggle Industrial Boiler Operations dataset](https://www.kaggle.com/datasets/nikitamanaenkov/time-series-of-industrial-boiler-operations/data) by Nikita Manaenkov. The fault window is synthetic — the original dataset contains no labeled fault events.
