Determination of the processing capacity of loading sites equipped with car dumpers for operation in winter conditions

Abstract

   The article considers the issue of choosing the parameters of coal unloading sites equipped with car dumpers in winter conditions. These conditions are limiting when calculating the processing capacity, because in the technological process of unloading, additional operations are added to warm up the wagons, contributing to the separation of cargo from the wagon body and its defrosting.
   The parameters of processing capacity in winter are lower than in summer, so this period of time is included in the calculations of processing capacity as the main one. This makes it possible to ensure a given processing of the car traffic in winter and to set the parameters of the infrastructure of an industrial enterprise for making design decisions and conditions for the interaction of mainline and industrial transport. The adopted design solutions for winter time are redundant for summer time and carry an additional burden in the form of capital costs and operating costs for industrial enterprises engaged in coal unloading.
   Reducing the gap in the values of processing capacity between summer and winter time when using car dumpers makes it possible to use loading sites more efficiently, reduce the duration of the company's track development and increase the reliability of the interaction of railway stations of the common network of railways and industrial enterprises.
   The article provides examples of several GRES and CHP plants processing capacity, as well as calculations and dependences of the wagons heating places capacity, taking into account the size of the wagons supply for unloading to the car dumper. Combinations of the heating devices capacity, the size of a group of wagons supply and the processing capacity are proposed in tabular form, which should be taken into account when designing places for loading frozen goods.
