(JP4050292-A)      Apparatus includes heating reactor (1) for melting and gasifying synthetic oil by heating, condenser (5) for converting gas to oil, heat exchanger (36), and warm water unit (37). Heating reactor (1) includes heating kiln (2), and heating furnace (4) for heating kiln (2). Heat exchanger is connected between heating reactor and condenser, and gas generated in heating reactor is transferred to condensor (5) after the heavy component is removed in heat exchanger (36). Casing (43) of heat exchanger is provided with inflow opening (38) for gas from heating reactor (1) and outflow opening (39) for cooled gas. Inflow opening (38) is connected to heating reactor. Casing (43) is provided with warm water path (40) at bottom for heating heavy component. Warm water path (40) is connected to warm water unit (37) to feed warm water. Heat exchanger (36) gas-tightly penetrates casing (43), and air pipe (41) is fixed to heat exchanger (36). Air pipe (41) has air opening opened at end, and outer periphery of air pipe (40) faces gas path inside casing. Wax discharge opening (42) is opened at bottom of casing (43) under discharge opening (39).    USE/ADVANTAGE -   Heavy component can be effectively removed. Converts synthetic resin to oil.    (JP4050293-A)      Appts. includes heating reactor (1) for melting and gasifying synthetic resin by heating. Reactor (1) includes heating kiln (2), stirrer (3), and heating furnace (4). Stirrer (3) includes bottom-stirring vanes (10) for stirring melted synthetic resin and upper stirring vanes (6) for stirring gasified synthetic resin.    USE/ADVANTAGE -   Gas not sufficiently decomposed to low molecules can be prevented from being fed to condenser (5). Converts synthetic resin to oil.    (US5316734-A)      Appts. for converting synthetic resin into oil comprises a vessel (2) heated by a furnace (4) surrounding the lower part of the vessel, with the upper exposed to ambient atmos. A solid resin feed conduit (13) to the vessel has spaced valves (14) forming a temporary holding chamber (16) and operated oppositely to feed resin without opening the vessel to atmos..    A stirrer in the vessel has a motor-driven (11) shaft (9) with a radial blade (10) on its lower end. The blade lower edge conforms to vessel surface shape to scrape off material accumulating during operation. The blade ends pref. extend upwardly to at least the level of the lower edge of insulation (12) around the middle section of the vessel.    USE/ADVANTAGE -   Partic. for conversion of scrap resin. Gives a high oil yield with only small amts. of residual material left in the vessel.    (JP94081836-B2)      The installation for converting plastics (e.g. plastic waste) into oil has a thermal-reaction arrangement (1) for heating, melting and vaporising the material. There is a heating tank (2) with an agitator (3), and a furnace (4) for heating the tank.    The installation includes any suitable feed mechanism and a delivery chamber. The heating tank, with pref. 15-40% of its height protruding from the furnace, has a body shaped to allow the agitator, with its blades, to stir up the plastics close to the inner surface of the tank body and, together with the scraping action of the blades, inhibit a build-up of material there. Gaseous mixt. from the heating tank is cooled in the condenser and liquefied to produce oil, which goes into the oil tank. The burner burns oil that has been converted in the installation, so that no extra fuel is necessary.    USE/ADVANTAGE -   The installation produces a high proportion of oil from the plastics, and leaves only a small amt. of residue in the heating tank, thereby overcoming a serious drawback of such installation.
