A Novel Multi-Mode Bayesian Method for the Process ...

Process monitoring and fault diagnosis (PM-FD) of coal mills are essential to the security and reliability of the coal-fired power plant. However, traditional methods have difficulties in addressing the strong nonlinearity and multi-modality of coal mills. In this paper, a novel multi-mode Bayesian PM-FD method is proposed. Gaussian mixture model (GMM) is first applied to …

Why hydrogen-fired power plants 'will play a major role in ...

While it would be theoretically possible to convert a coal-fired power plant to run on hydrogen, Zindel says it would be too expensive to be cost-effective. This is because coal power plants generate electricity by burning the hydrocarbon to heat water, which generates steam that drives a steam turbine.
