Description: |
| Abstract:
The drawing shows a section of an ordinary sized smelting-furnace on a scale of an inch to a foot, and represents such part thereof as is necessary to a clear understanding of my invention, which consists in a mode of introducing the air from the blowing apparatus diffusedly-without impinging upon the ignited fuel, as it does when introduced through the tuyere in the ordinary way, by which diffusion there is an essential difference in the results produced, the action of the air being, from the very commencement of its introduction, by gradual and easy pressure.
Claim:
The diffusing of the blast in a chamber as it enters a furnace. |
