Abstract
A process for absorbing the heat from the cooling and solidification of metallurgical slags and converting of said heat into a useful form of energy such as steam. The molten slag is poured against a moving heat-transfer surface and is cooled by contact with said surface. Energy is released to said heat-transfer surface during the cooling process and is, in turn, transmitted to water which is converted to steam. Included with the process are necessary piping, steam drum, pumps and heat insulation.
Claims18
A process for cooling and solidifying molten slag and converting heat removed from the slag into a useful form of energy comprising:
- a. forming a pool of molten slag maintained in contact with a heat-transfer surface moving relative to said pool;
- b. pouring fresh molten slag into said pool of molten slag;
- c. cooling and solidifying slag from said pool on said heat-transfer surface while transferring heat from said cooled and solidified slag to said heat-transfer surface;
- d. scraping said solidified slag from said heat transfer surface;
- and
- e. absorbing said heat from said heat-transfer surface into a heat absorber for making further use of said heat.
An apparatus for cooling and solidifying molten slag and converting heat from the slag into a useful form of energy, comprising:
- a. a rotatable heat-transfer surface to cool and solidify said slag while absorbing heat from said slag;
- b. means for maintaining a stationary pool of molten slag in contact with said heat-transfer surface;
- c. means for pouring molten slag into said pool;
- d. means for scraping solidified slag from said heat-transfer surface;
- and
- e. means for absorbing heat from said heat-transfer surface into a heat absorber for making further use of said heat.
