Title: A method for recovering volatile constituents from carbonaceous materials
Inventor: FAHLSTROM PER ANDERS HERMAN H
IPC: C10J3/00
Filed: 1980-04-11
Granted: 1983-04-14
Abstract: PCT No. PCT/SE80/00105 Sec. 371 Date Dec. 12, 1980 Sec. 102(e) Date Nov. 5, 1980 PCT Filed Apr. 11, 1980 PCT Pub. No. W080/02149 PCT Pub. Date Oct. 16, 1980.Disclosed is a method for recovering oil and gas from carbonaceous materials utilizing two molten baths. In the first molten bath reaction vessel, the carbonaceous material is thermally devolatilized. Part of the first melt from the first reaction vessel containing non-volatile constituents is passed to the second molten bath reaction vesel which contains a different melt at a higher temperature. The two melts are only partially soluble in each other so that they can be easily separated. Oxygen, air or oxides are charged to the second reaction vessel for gasifying residual quantities of carbon by oxidation. The first melt is returned to the first reaction vessel from the second reaction vessel. The melt in the first reaction vessel may comprise lead or zinc and be maintained at a temperature of 500 DEG  C., while the melt in the second reaction vessel may comprise raw iron and be maintained at a temperature of 1200 DEG  C.

Title: Apparatus for the gasification of pulverized coal
Inventor: RAFAEL ARUTH
IPC: C10J3/76
Filed: 1980-05-12
Granted: 1983-10-27
Abstract: An arrangement for pressure gasification of fine-grain coal in which the exit of a reactor is followed by a waste heat boiler for cooling the generated gas. The waste heat boiler has a radiation section and downstream heat exchanger surfaces. The reactor is provided, furthermore, with cooling cubes which are studded and lined with refractory ramming mix. The radiant type heating surfaces are sized so that the gas temperature at the exit of the radiation section is situated below the ash sintering temperature of the coal being used. On gas sides, the radiation section is followed by a pressure vessel accommodating convection type heating surface banks which are swept by the generated gas. The radiation section may be in the form of two gas passages through which the gas flows successively. These gas passages are formed by the tube walls welded between each other in a gas-type manner.

Title: Apparatus for recovery of heat from fumes in a heating system or from the ambient air
Inventor: CURTI PAOLO
IPC: F24D17/00
Filed: 1982-10-25
Granted: 1986-10-16
Abstract: The apparatus includes a condenser (4), through which passes a duct (3") that carries, downward, the fumes from heating boiler (1) to bring them into a lower chamber (5). The fumes are mixed with ambient air in this chamber (5), a mixture that is then moved upward, going through the evaporator (4) by the action of a fan (9), placed contiguous to the collection chamber (10), placed above the evaporator (4).Together with the recovery of heat from the fumes there is a recovery of the heat contained in the ambient air.Besides the high efficiency that can be obtained with a limited capital investment, in the case of fumes the apparatus purifies them of the solid particles in suspension and even noxious gaseous components.The apparatus is used independently of the hot gas, for example, to heat water for domestic use.The air that is exhausted by the fan (9) after having given up its heat inside the evaporator (4) can be used for conditioning a closed area.
