Abstract
Heating apparatus is described that is particularly adapted for thawing frozen particulate material in railroad hopper cars. The apparatus is a low profile, fuel-fired heater adapted for installation between rails traversed by the hopper cars within a thawing shed. The construction employs heat-radiating metal plates forming an elongated gas-conducting chamber through which high velocity combustion gases are conducted. The arrangement of plates is such as to enhance the emission of radiant heat to the hopper car bottoms with appropriately positioned heat insulated regions to protect hopper car brake hoses, or the like, from damage caused by overheating.
