| Hearth furnaces | Mining | Furnaces in which the charge rests on the hearth or kiln wall and is heated by hot gases passing over it. Even though hearth furnaces such as the multiple-hearth roasting furnace and rotary kilns operate on the same basis as reverberatory furnaces, they bear little resemblance to them. (references) | |
