Present systems for fire detection in industrial coal pulverizers use either thermocouples to measure the rise in outlet temperature of the pulverizing mill or infrared gas analyzers to detect the buildup of CO produced in the mill. Thermocouples or RTDs are normally part of the control system for mill operation.
This is one reason why manual sampling yields erroneous data and results worsen if the coal mill does not distribute its coal equally to the coal pipes. In Figure 2, the coal mill delivers a ...
Safety precautions. in Coal handling amp firing. Asec Academy Safety precautions in Coal handling amp firing. To achieve the goal of safe, efficient, and economical coal firing system designs, both users and regulatory personnel must have an understanding of the hazards involved in coal fired systems and the nature of the problems involved in the use of pulverized coal.
SECTION 5. FIRE FIGHTING MEASURES Fire and Explosion Hazards Solid coal is not readily combustible but can be ignited through sustained contact with an open flame. Finely-divided coal dust is a moderate fire and explosion hazard, particularly when dispersed in the air at high
Jan 01, 2013 The heat that is required is a product of the temperature and quantity of airflow at the mill inlet. Because subbituminous coal is 15 to 30 moisture, very hot mill inlet temperatures are ...
