Final heating temperature of ventilation air heating in multi-row mine air heater calorifier units

Abstract

It is known that at the vast majority of mines located in areas with severe climate, in winter time part of the atmospheric air supplied to underground workings for their ventilation is heated. To this end, at shafts and adits where the ventilation air comes, steam air heater units with a multi-row arrangement of metal plate air heaters are usually constructed; the sequential movement of heated air in them provides the necessary air temperature drop...
