ABSTRACT:
Methods of and systems for preventing air pollution in the handling and storing of particulate solids out-of-doors in bulk form; i.e., in a pile. A windfoil arrangement keeps material from being entrained in wind blowing over the pile and thereby causing an air pollution problem. The problem is particularly acute when material is being dumped; it also arises when wind strips the particulate material from the pile, and it can result in the particulate material being scattered over a widespread area (typically one mile or more in radius) which indicates that the air pollution is not restricted to the immediate vicinity of the area in which the material is stored.
