<p>1520240 Gasifying waste UNION CARBIDE CORP 25 May 1977 [26 May 1976] 22014/77 Heading C5E A process for disposing of refuse while simultaneously producing a useful gaseous product and an inert solid residue, comprises the steps of (a) feeding refuse into the top portion of a vertical shaft furnace, (b) feeding an oxygen-containing gas into the base of said furnace, (c) pyrolyzing the organic portion of the refuse, (d) fluidizing the inorganic portion of the refuse, (e) discharging the gaseous products from the top of said furnace, and (f) tapping the fluidized inorganic material from the base of said furnace, wherein char is removed from the furnace in an amount such that oxygen consumption in said process is reduced, while a sufficient amount of combustible materials is retained in the furnace so that on oxidation thereof the energy requirements of the process are satisfied, the amount of char removed (kgs. char/metric ton refuse) being less than the value of 50X/Y, where: X = kgs. carbon contained in a metric ton of refuse, Y=weight per cent (%) carbon in the char and wherein the range of oxygen consumption for a given amount of char removed will be within the values determined by the equation: R=B-(8Î10<SP>-6</SP>) (CY) where: R = oxygen consumption (metric tons oxygen/metric ton refuse), C = char removal (kgs. char/metric ton refuse), Y is the same as above, and B can vary between 0À15 and 0.28.</p> |
