Oct 21, 2011· Description of the inerting process in coal-grinding systems Inerting systems avoid dust explosions and smouldering fires in silos, coal mills and filter equipment by creating an inert atmosphere. In the case of abnormal levels of carbon monoxide (CO), oxygen or heat, the inerting process is initiated automatically through a process-control system.
Sep 01, 2000· With the increased potential for explosions when sub-bituminous coal is used, it becomes more important to provide pulverizers with manual fire suppression systems. These type of systems …
A tube bundle system (TBS) is a mechanical system for continuously drawing gas samples through tubes from multiple monitoring points located in an underground coal mine. The gas samples are drawn via vacuum pump to the surface and are typically analyzed for oxygen, methane, carbon dioxide and carbon monoxide.
A safety control system for a coal pulverizer utilizes signals (20,22) representing net oxygen and carbon monoxide measurements of the pulverizer atmosphere. A signal (50) representing the rate of carbon monoxide change is derived form the signal (22) by a derivative controller (48). The signals (20,50) representing the net oxygen measurement and rate of carbon monoxide change are …

CS0352-MP Gas Sampling System. Conspec's CS0352-MP carbon monoxide gas sampling system detects smoldering hot spots in your mill/pulverizer. The dual probe system allows for detection of elevated carbon monoxide levels in separate areas to provide an extra layer of protection against fire situations like "mill puffs".
Often called the invisible killer, carbon monoxide is an odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely. In the home, heating and cooking equipment that burn fuel are potential sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of carbon monoxide.
of carbon monoxide (CO) gas. Choosing the most-appropriate monitoring technique depends on both the measurement location and the degree of risk. More sophisticated, and therefore more expensive, monitors are appropriate where large volumes of pellets are being handled and the consequences of spontaneous combustion are more serious.
