Identification and control of sources of airborne coal dust at large-storage coal piles. Paper 80-11. 4

An investigation was made to identify the principal sources of airborne coal dust from coal pile operations at the Nanticoke Thermal Generating Station, Nanticoke, Ontario, Canada. Dust particle size distributions and emission rates from different sources on the coal pile were measured and dispersion calculations made to estimate the impact of these emissions on the area surrounding the station. In addition, studies were made to evaluate the effectiveness of coal dust control agents to reduce the dusty character of coal as well as physical model studies in an open channel water flume to determine the optimum shape of the coal pile. The application of these results to the Nanticoke coal pile is discussed.
