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.
