METHOD AND APPARATUS FOR PRODUCING SUPERHEATED STEAM USING HEAT GENERATED THROUGH INCINERATION OF WASTES

摘要

Method and apparatus for producing superheated steam using heat generated through incineration of wastes in which boiler water is used that is pressurized so as to have a boiling point of about 200 to 320 DEG C, the heating of the boiler water being effected in a plurality of steps, at least two steps, in which the heating of the boiler water up to the boiling point is effected by chlorine containing thermal energy, and in which super-heating from the boiling point to a predetermined temperature to obtain superheated steam is effected by dechlorinated thermal energy, the method and apparatus being characterized in that the heating by the chlorine containing thermal energy is effected by using thermal energy obtained through combustion of pyrolysis gas that is obtained by thermal decomposition means for effecting a pyrolytic reaction by supplying wastes into a space containing a fluid medium having a temperature of 300 DEG C or greater, and in that the heating by the dechlorinated thermal energy is effected by using thermal energy obtained by char combustion means for burning non-decomposed residuals taken out of the thermal decomposition means while a char mixture comprising the non-decomposed residuals and fluid sand is caused to flow by air.
