Abstract: The heating method, more particularly for dwellings, in which a pulverulent or granular mixture comprising a plastic and a stabilizing agent, which is vortexed with air in a dry mixer, in which the outer wall of the dry mixer, for the dissipation of heat, is circumcirculated with water circulating in a heating circulation system, consists in that, as a stabilizing agent for the small plastic particles, a mercaptide is used and/or in that the vortexing is performed in a reposingly disposed container extending via a vortexing path over a horizontal area; which is carried out in a device comprised of a double-walled container (10) with a vortexing means of a wing mixer (20), while water is circulated as a part of a heating circulation system in the interspace of the double wall (11, 12), and in that the preferably cylindrical container is disposded so as to be reposing and is provided with a wing mixer (20) capable of rotating about a horizontal shaft (FIG. 1).

Abstract: The method in accordance with the invention comprises a rolling of the liquid slag between at least two cooling rolls of metal, preferably steel, the temperature of and the distance between the rolls being controlled such that a cohesive slag slab is obtained having a solidified surface layer and a melted central layer, the slab still being sufficiently plastic to be shapable, a shaping in conjunction with the rolling or after the same, of the slab into briquettes and a recovery of heat at least from the shaped briquettes, preferably after these have been separated from each other, via any suitable cooling means or medium.The apparatus in accordance with the invention comprises at least two cooling rolls (1) arranged to roll out the liquid slag into a cohesive, shapable slab, means (4) for briquetting the slab and means (5,7) for recovering heat from the shaped briquettes.

Abstract: To recover the sensible heat of slag the slag is allowed to solidify on the surface of a hollow cooling body provided with a liquid internal cooling and is indirectly cooled by the liquid internal cooling. The liquid cooling medium of the liquid internal cooling is guided in a thermodynamic cyclic process. In order to ensure as completely a recovery of the sensible heat of the slag as possible and a high percentage of glassy portions of the slag as well as a good grindability of the slag, the liquid slag on the surface of the cooling body is intensively cooled indirectly by the liquid cooling medium to a temperature of closely below the solidification temperature in a first cooling step. The solidified slag separated from the surface of the cooling body is then directly cooled by a gas flow in a second cooling step. The heated gas flow also is guided in a thermodynamic cyclic process.

Abstract: Method and apparatus for cooling hot bulk material, such as red-hot coke, sinter, or clinker, and, in particular, for relieving a gas stream flowing through the hot bulk material to cool the same includes continuously charging hot bulk material into a cooler housing and onto the free surface of spread bulk material already contained within the cooler housing and cooling the hot bulk material by absorbing and removing the intensive heat radiation radiated from the surface of the hot bulk material in a radiation cooling surface extending over in facing relationship to the free surface of hot bulk material.

Abstract: A process for recovering energy from substances having a high temperature, in particular for recovering energy from molten slag material obtained in metallurgical processes, the heat being emitted by said substances by radiation, being recovered in regions, positioned at distance from said substances. In case of liquid substances such as molten slag material, this is conveyed during the recovery of radiation heat.

Abstract: A cooler for combustible material has a first section of cooling grate which is traversed by a cooling air that is fed completely to a burner as air for combustion, and has a further section likewise traversed by cooling air under the effect of at least one ventilator or blower wherein the ventilator is driven directly by a steam turbine, and that with the second section or another further section of the cooler, a steam generator is connected with the turbine.

Abstract: A process and apparatus for absorbing heat from the cooling of metal slabs and other metal products following rolling, casting, or other heating to shape the metal products, and the converting of the heat to a useful form of energy. During the process of cooling the metal products, heat from the metal is transferred to an absorbing medium by means of radiant and convective or conductive heat transfer. The absorbing medium may be water which is converted to steam. The apparatus includes necessary piping, circulating fan, steam drum, pumps and heat insulation.

Abstract: Molten slag in a vessel or vessels is placed below heat absorbing tubes through which water is passed and converted into steam by the heat radiated by the slag of high temperature, the heat thus being recovered by utilizing the steam for heating purposes, or for driving a turbine or the like. A cover is placed over the tubes and the vessel or vessels to increase the heat transfer efficiency. Any cooled slag layer formed on the surface of the molten slag in the vessel is removed by skimming to promote the heat transfer and, after the temperature of the slag in the vessel has lowered to about 1,200.degree. C, the slag is agitated to further promote the heat transfer. Alternatively, the slag in the vessel or vessels is agitated from the beginning until its temperature has lowered to about 700.degree. C.
