Abstract

See full text

A system for detecting a combustion-related condition in a pulverizer includes a pulverizer configured to receive coal chunks via an inlet, to grind the coal chunks into coal powder and to output the coal powder via an outlet. The system includes sensors configured to detect heat input characteristics supplied to the pulverizer and heat output characteristics emitted from the pulverizer. The system also includes a controller configured to determine, based on signals from the sensors, whether a combustion-related condition exists in the pulverizer based on a heat balance function including the heat input characteristics and the heat output characteristics.
