Atmospheric Co Furnace Generator

An item used to produce an exothermic type of atmosphere for use in heat treating furnaces to prevent surface oxidation of ferrous materials, where decarburization is not a factor, by partially burning a predetermined quantity of hydrocarbon gas with air in a refractory insulated combustion chamber. Used for such processes as annealing, tempering of steel, copper or silver brazing of steel, silver brazing on non-ferrous mixture in powder metallurgy and sintering of carbon powders.
