The role of coal fired plants in power generation is changing, with an increasing number covering peak demand, rather than baseload. This, combined with the pressure to reduce carbon emissions, is encouraging operators to introduce significant plant upgrade programmes so they can operate their fleet in the most economic and environmental manner.

Section snippets Modeling of primary air. In this study, the lumped parameter method was adopted to make the following assumptions for the inlet primary air of the coal mill: 1) the parameters of the medium in the primary air duct are uniform; 2) the medium in the primary air duct is incompressible; and 3) the change in flow power in the primary air duct is negligible.

CO2 emissions from coal power generation could be reduced by maximizing the amount of torrefied biomass that can be used in pulverizedcoalfired power plants. In this study, to evaluate the milling performance of coal and torrefied wood pellets (TPs), various blend ratios were tested using a benchscale roller mill. Neutral sugar analysis was performed to evaluate the biomassderived part of ...

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 ...

The results showed a more rapid convergence of the plant output to the set point when the predictive control strategy was applied against the current one. A more indepth approach in coalmill operation and control are available in [58,59]. The reader may refer to those, since the analysis of coalmill operation goes beyond the scope of this paper.
