Coal Dust Control

Worldwide, coal production and use has been plagued by dust and spontaneous combustion problems.  Dust represents a loss of product and is a contaminant, and health threats.  Coal dust control is critical due to the risk of coal dust explosions, the lung disease known as pneumoconiosis (black lung disease).  In addition to creating safety and environmental hazards, coal dust increases the cost of maintaining material handling equipment.
 
Similar to sand, coal is stored outside in piles where it absorbs water every time it rains.  Higher moisture content reduces coal's ability to burn efficiently.  Attempts made to address these problems usually involve water.  Products designed to retain or extract water from the air, primarily “salts”, frequently have negative side effects on the environment and are also individually limited by ambient humidity.  The use of water and other types of dust control methods are only effective for a short period of time and must be reapplied frequently to maintain their effectiveness. 
 
Long standing problems of wind generated dust from coal storage piles, loss of fines from coal rail wagons, and the water consumption necessary to prevent auto combustion during transport and storage can reduced by applying  one of two new proprietary products which form a flexible surface “crust” after applied.
Once applied, these products bond the particles together to form a protective barrier that eliminates windblown dust with just a single application.  Spraying DustLess or DirtGlue Polymer on the surface of coal successfully minimizes the absorption of water.
