Introduction Despite the recent surge in renewable energy, fossil fuels including coal are expected to provide nearly 22% of the global power and account for majority of CO 2 emissions by 2040 (IEA, 2021). Therefore, identifying ways to optimize operation of existing and upcoming coal fired power plants is essential.

As mentioned in Section 1, the change of coal in a thermal power plant typically happens over a period of several hours (referred to as coal transition) and there is an irregular time lag between the coal change at the bunker level and that at the mill or boiler level (Tuttle et al., 2020). Therefore, realtime detection of change of coal in an ...
