Fuel gas may be burned as rapidly as possible by thorough premixing or as slowly as possible by the elimination of all effects tending to accelerate the mixture of air and gas. In the latter case, combustion occurs through molecular interdiffusion, hence, “diffusion combustion.” The diffusion flame has unique properties as a heat radiator, not necessarily associated with visible luminosity, which are attained by liberating the maximum quantity of free suspended carbon from a given volume of gas. These properties make possible greater uniformity of heat distribution and lower temperature gradients than are possible with any other type of combustion. The combustion requirements of the ideal glass tank, which include maximum utilization of the melting surface, heat penetration into the bath, and convection current control, are well met by diffusion combustion.
