Abstract
In a method of controlling the pulverization and dryness of a flammable material such as coal, the system is provided with both a push blower upstream from the pulverizer and a pull blower downstream from the pulverizer. The system is controlled so as to maintain the pressure within the pulverizer at an average equal to substantially the atmospheric pressure. In the method for controlling the pulverizing rate, a preset desired differential pressure across the pulverizer is maintained constant while the pulverizing motor speed and the pulverizing material feed rate are modified.
