Abstract
A safety control system for a coal pulverizing mill is disclosed. The control system utilizes measurements of the net oxygen level and the carbon monoxide equivalent (CO.sub.e) level of the combustible gases within the pulverizing mill. First levels of the net oxygen and the rate of carbon monoxide equivalent change in the pulverizing mill are utilized in a control logic system to actuate alarms. Second levels of the net oxygen and the carbon monoxide equivalent (CO.sub.e) level in the pulverizing mill are utilized to accomplish the inerting of the mill.
