RESEARCH OF THE PROCESS OF HEATING DUMPS APPLIED ON MUNICIPAL EQUIPMENT

Abstract

In the process of cleaning public roads, the snow layer is mixed with reagents, dust, small debris and pollution. As a result, the adhesion in the resulting mixture to the surface of the metal dumps increases significantly. The resistance to shear of the snow mass along the surface of the dump increases. An increase in temperature on surfaces under negative temperatures leads to the formation of a thin layer of water at the border between surroundings. It is assumed that heating the dump with the exhaust gases from the machine will significantly reduce the adhesion of snow on its surface and create a thin water film, leading to a decrease in the friction force when the snow mass moves along the dump. The article proposes a practical application of the exhaust gas heating system for the dump The question of the influence of the time of heap heating with applied heating from exhaust gasses system forming water firm at the interface are considered.
