Pulverizer Application for High Volatile High Moisture Coals
600-700 OF inlet temperatures experience high incident rates of pulverizer fires. The greatest fire potential exists when an operating pulverizer is removed from service while fully charged with coal.5 A high pulverizer inlet temperature provides high conductive heat transfer suffi- cient for spontaneous combustion.mill outlet temperature pulverizer fire hm2ei,Nov 27, 2019 An exhauster mill limitation A derate is due to the calculated airflow required with all pulverizers in service is greater than the actual exhauster fan flow. Improper pulverizer outlet temperature A derate is due to the heat available in the primary air for drying coal in the pulverizers is less than that required. 26-Nov-19 Manohar,Pulverized Coal Firing Systems Testing & Diagnostics,Pulverizer Set up This normally includes the adjustment of classifier settings, balancing the fuel flow through the PC pipes, setting the mill outlet temperature control limits and calibrating the primary air flow measuring device.
