ABSTRACT:
A tripper car adapted to transfer particulate material such as coal while maintaining a reduced level of dust proximate the area in which said tripper car moves. The tripper car continuously receives coal from a moving conveyor belt and transfers the coal from a first to a second location. At the second location, the tripper car discharges the coal to a silo that stores the coal for subsequent use by boilers. The tripper car sprays liquid, such as water, to reduce the accumulation of coal dust within a structure in which the tripper car operates as well as to wash the inner walls, ceiling and other proximate surfaces to reduce accumulation of coal dust. The spray pattern is oriented to reduce the spraying of liquid on the coal.
