摘要： This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and/or an additive agent to raise its temperature to 250-350° C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500° C. It is maintained at this temperature until pyrolysis occurs. In order to obtain high-quality oil with a low boiling point, a first gas/liquid separation process separates the product obtained from the aforesaid pyrolysis into liquid high-boiling point oil, gaseous low-boiling point oil and low molecular-weight gases, and recirculates the liquid high-boiling point oil to the pyrolysis process, and a second gas/liquid separation process separates the gaseous low-boiling point oil and low molecular-weight gases into liquid low-boiling point oil and low molecular-weight gases. The first and second gas/liquid separation process are connected in sequence.

摘要： According to the present invention, boiler water is pressurized so that its boiling point is set at approximately 200.degree. C. to 320.degree. C. The boiler water is heated in at least two stages. Thermal energy of gases containing chlorine compounds is used to heat the water to its boiling point. Thermal energy of gases which do not contain chlorine compounds is used to heat the water from its boiling point until superheated steam of a given temperature is generated. The heating which uses the thermal energy of gases containing chlorine compounds is accomplished using the thermal energy from the combustion of pyrolysis gases obtained from a pyrolysis means in which waste material is supplied into a chamber containing a fluidized bed medium which has been heated to at least 300.degree. C., and a pyrolytic reaction is induced. The heating which uses the thermal energy of gases which do not contain chlorine compounds is accomplished using the thermal energy obtained from a char combustion means to combust char in which a char mixture consisting of unpyrolyzed residue and fluidized bed medium removed from the pyrolysis means is fluidized by a stream of air, and the unpyrolyzed residue is combusted.

摘要： A method of preventing dust from adhering to a wall of a combustion apparatus, such as a furnace wall or exhaust duct, is carried out by forcing gas through a porous refractory member forming the wall. Specifically, the furnace wall or exhaust duct wall to which dust might otherwise adhere is made of a porous refractory member and gas is injected through the pores of the refractory member. In an incinerator, the refractory porous member extends around the periphery of a liquid injection nozzle, so that gas fed to the inside of the incinerator through the refractory porous member prevents flower from accumulating at the periphery of the end of the nozzle and attenuates the wake of the injected liquid so as to suppress the entrainment of dust in the liquid. In a melting furnace, the refractory porous members provide the ceiling of a slag separating chamber and the entrance of an exhaust gas duct open to the upper portion of the slag separating chamber. Plate-like members form wind chambers with the porous refractory members so that cooling gas fed into the wind chambers is forced into the slag separating chamber and exhaust duct through the pores in the refractory porous members.
