Combustion Interlocks: The mill system is tightly interlocked with the boiler/burner management system. A mill trip will automatically trip associated burners and may initiate a furnace purge.
Advanced Process Control (APC): Modern systems use model-based predictive control to optimize the mill load in response to boiler demand, balancing several mills for optimal efficiency, and predicting maintenance needs based on trend analysis of power consumption and pressure differentials.
This integration of robust passive safety design with intelligent, proactive automation ensures that the coal preparation system operates not only efficiently but with the highest level of inherent safety, protecting both personnel and capital investment.
