  • Coal Pipe Balancing Airflow Sciences

    Since each pulverizer supplies coal to a number of pipes, there are many opportunities for imbalances to occur The primary issue is that the pipes have different destinations, thus creating discrepancies in the length, number of bends, and flow resistance of each pipe A carefully designed system will ensure that the resistance of each of those branches is equal so that the coal and air split
