NUMERICAL STUDY OF THE SURFACE THAWING OF COAL CARS

Wide-scale transportation of coal by rail from mines in Northern regions of the continent is likely to be undertaken in the future. During winter the moisture in the coal tends to freeze causing the coal to adhere to the surface of the car making it difficult to discharge the coal from the car. The most common method used to break the bond between the frozen coal and the car surface is to pass the cars through a thaw-shed in which they are exposed to infrared heaters. Some aspects of the thawing in such sheds have been numerically investigated using a relatively simple one-dimensional finite-difference type solution of the governing equations. The effects of the governing parameters on the degree of thawing have been investigated and some conclusions regarding thaw-shed design have been reached.
