Abstract
A safety control system is disclosed for a coal pulverizer utilizing the measurements of net oxygen and carbon monoxide measurements of the pulverizer atmosphere. First levels of net oxygen and rate of carbon monoxide change are utilized in a control logic system to actuate alarms and automatic inerting of the pulverizer is accomplished utilizing a second level of net oxygen measurement and absolute carbon monoxide level in the pulverizer.
