Based on the physical model for operation parameters of power unit and ball motion, the results of Matlab and Origin show that the trajectory of milling balls varies with coal storage during the coal pulverizing process, and the impact energy of balls can be calculated. The relationship between coal storage and boiler load is better than primary air flow, secondary air flow and main steam ...

Coal Mill Safety parameters: Position of Explosion vents. Operational readiness of quick shutoff dampers. Inertization section readiness (N2, CO2 pressure in bars)
Process parameters such as temperatures and concentrations of CO and O 2 are monitored by a distributed data acquisition and control system. Spontaneous combustion of coal is the most possible ignition source, and CO monitoring is an effective method to detect spontaneous combustion. Experiences show that, autoignition may occur in the drying system when CO concentration is above .

Electromagnetic mill. The drying of the lignite coal in the electromagnetic mill comes under the thermalmechanical method of drying of the brown coals. In this method, coal is heated by steam at elevated temperature of 150 deg C to 200 deg C and at the pressure ranging from 5 atmospheres to 16 atmospheres It is then compressed in a hydraulic press to squeeze out the water. The electromagnetic ...
